==History==

===The Manhattan Project===
{{Main|Project Y}}
The laboratory was founded during [[World War II]] as a secret, centralized facility to coordinate the scientific research of the [[Manhattan Project]], the [[Allies of World War II|Allied]] project to develop the first [[nuclear weapon]]s.<ref>Force V: The history of Britain's airborne deterrent, by Andrew Brookes. Jane's Publishing Co Ltd; First Edition 1 Jan. 1982, {{ISBN|0710602383}}, p.2.</ref> In September 1942, the difficulties encountered in conducting preliminary studies on [[nuclear weapon]]s at universities scattered across the country indicated the need for a laboratory dedicated solely to that purpose.{{citation_needed|date=July 2019}}

General [[Leslie Groves]] wanted a central laboratory at an isolated location for safety, and to keep the scientists away from the populace. It should be at least 200 miles from international boundaries and west of the Mississippi. Major [[John H. Dudley|John Dudley]] suggested [[Oak City, Utah]], or [[Jemez Springs, New Mexico]], but both were rejected. Jemez Springs was only a short distance from the current site. Project Y director [[J. Robert Oppenheimer]] had spent much time in his youth in the New Mexico area and suggested the [[Los Alamos Ranch School]] on the [[mesa]]. Dudley had rejected the school as not meeting Groves' criteria, but as soon as Groves saw it he said in effect "This is the place."<ref>

During the Manhattan Project, Los Alamos hosted thousands of employees, including many [[Nobel Prize]]-winning scientists. The location was a total secret. Its only mailing address was a post office box, number 1663, in [[Santa Fe, New Mexico|Santa Fe]], New Mexico. Eventually two other post office boxes were used, 180 and 1539, also in Santa Fe.<ref>

[[File:Trinity Test Fireball 16ms.jpg|left|thumb|The first stages of the explosion of the [[Trinity (nuclear test)|Trinity nuclear test]]]]
The work of the laboratory culminated in several atomic devices, one of which was used in the first [[nuclear testing|nuclear test]] near [[Alamogordo, New Mexico]], codenamed "[[Trinity (nuclear test)|Trinity]]," on July 16, 1945. The other two were weapons, "[[Little Boy]]" and "[[Fat Man]]," which were used in the attacks on Hiroshima and Nagasaki. The Laboratory received the [[Army-Navy "E" Award]] for Excellence in production on October 16, 1945.{{citation_needed|date=July 2019}}

===Post-war===
After the war, Oppenheimer retired from the directorship, and it was taken over by [[Norris Bradbury]], whose initial mission was to make the previously hand-assembled atomic bombs "G.I. proof" so that they could be mass-produced and used without the assistance of highly trained scientists. Other founding members of Los Alamos left the laboratory and became outspoken opponents to the further development of nuclear weapons.{{citation_needed|date=July 2019}}

The name officially changed to the '''Los Alamos Scientific Laboratory''' ('''LASL''') on January 1, 1947. By this time, [[Argonne National Laboratory|Argonne]] had already been made the first National Laboratory the previous year. Los Alamos would not become a National Laboratory in name until 1981.<ref>{{cite book |title= Plans and Practices for Groundwater Protection at the Los Alamos National Laboratory |publisher= National Research Council |page=5 |url= https://books.google.com/books?id=smObAgAAQBAJ&pg=PT5|isbn= 9780309106191 |date= October 18, 2007 }}</ref>

In the years since the 1940s, Los Alamos was responsible for the development of the [[hydrogen bomb]], and many other variants of nuclear weapons. In 1952, [[Lawrence Livermore National Laboratory]] was founded to act as Los Alamos' "competitor," with the hope that two laboratories for the design of nuclear weapons would spur innovation. Los Alamos and Livermore served as the primary classified laboratories in the U.S. national laboratory system, designing all the country's nuclear arsenal. Additional work included basic scientific research, [[particle accelerator]] development, health physics, and fusion power research as part of [[Project Sherwood]]. Many nuclear tests were undertaken in the [[Marshall Islands]] and at the [[Nevada Test Site]]. During the late-1950s, a number of scientists including [[John Robert Beyster|Dr. J. Robert "Bob" Beyster]] left Los Alamos to work for [[General Atomics]] (GA) in [[San Diego]].<ref>

===Post-Cold War===
At the end of the [[Cold War]], both labs went through a process of intense scientific diversification in their research programs to adapt to the changing political conditions that no longer required as much research towards developing new nuclear weapons and has led the lab to increase research for "non-war" science and technology. Los Alamos' nuclear work is currently thought to relate primarily to computer simulations and [[stockpile stewardship]]. The development of the [[Dual-Axis Radiographic Hydrodynamic Test Facility]] will allow complex simulations of nuclear tests to take place without full explosive yields.<ref>{{Cite web |title=Berkeley Lab to Build Linear Induction Accelerator for DARHT |url=https://www2.lbl.gov/Science-Articles/Archive/DARHT-one.html |access-date=2025-07-08 |website=www2.lbl.gov}}</ref>

The laboratory contributed to the early development of the [[flow cytometry]] technology. In the 1950s, researcher Mack Fulwyler developed a technique for sorting [[erythrocytes]] that combined the Coulter Principle of [[Coulter counter]] technologies, which measures the presence of cells and their size, with ink jet technology, which produces a laminar flow of liquid that breaks up into separate, fine drops. In 1969, Los Alamos reported the first fluorescence detector apparatus, which accurately measured the number and size of ovarian cells and blood cells.<ref>{{cite book | url=https://books.google.com/books?id=sYZuiy4BbvUC&q=flow+cytometry+principles&pg=PR7 | title=Flow Cytometry First Principles | first = Alice | last = Givan |page=6| isbn=9780471459118 | date=April 5, 2004 | publisher=Wiley }}</ref>

As of 2017, other research performed at the lab included developing cheaper, cleaner biofuels and advancing scientific understanding around renewable energy.<ref>{{Cite web |title=Applied Energy Programs |url=https://www.lanl.gov/science-engineering/science-programs/applied-energy-programs |access-date=January 31, 2017 |website=Los Alamos National Laboratory}}</ref>

Non-nuclear [[national security]] and defense development is also a priority at the lab. This includes preventing outbreaks of deadly diseases by improving detection tools and the monitoring the effectiveness of the United States' [[vaccine]] distribution infrastructure. Additional advancements include the ASPECT airplane that can detect bio threats from the sky.<ref>{{Cite web |title=Los Alamos National Lab: National Security Science |url=https://www.lanl.gov/about/lab-agenda/biosecurity-preparedness |access-date=2019-10-24 |website=www.lanl.gov}}</ref>

====Medical work====
In 2008, development for a safer, more comfortable and accurate test for [[breast cancer]] was ongoing by scientists Lianjie Huang and Kenneth M. Hanson and collaborators. The new technique, called ultrasound-computed tomography (ultrasound CT), uses sound waves to accurately detect small tumors that traditional mammography cannot.<ref>{{cite book|last1=Huang|first1=Lianjie|last2=Hanson|first2=Kenneth M.|last3=Quan|first3=Youli|last4=Li|first4=Cuiping|last5=Duric|first5=Neb|editor2-first=Jan|editor2-last=d'Hooge|editor1-first=Stephen A|editor1-last=McAleavey|chapter=Globally optimized Fourier finite-difference method for ultrasound breast imaging|title=Medical Imaging 2008: Ultrasonic Imaging and Signal Processing |series=Proceedings of SPIE|volume=692007|pages=692007|doi=10.1117/12.771024|year=2008|s2cid=14509019}}</ref>

The lab has made intense efforts for [[humanitarian]] causes through its scientific research in medicine. In 2010, three vaccines for the [[Human Immunodeficiency Virus]] were being tested by lab scientist [[Bette Korber]] and her team. "These vaccines might finally deal a lethal blow to the [[HIV|AIDS virus]]", says Chang-Shung Tung, leader of the Lab's Theoretical Biology and Biophysics group.<ref>{{cite web|url=http://www.lanl.gov/news/releases/hiv_vaccine_strategy_expands_immune_responses_news_release.html |title=HIV Vaccine Strategy Expands Immune Responses |first=Bette |last=Korber |date=March 3, 2010 |publisher=Los Alamos National Laboratory |access-date=January 12, 2012 |url-status=dead |archive-url=https://web.archive.org/web/20111021050027/http://www.lanl.gov/news/releases/hiv_vaccine_strategy_expands_immune_responses_news_release.html |archive-date=October 21, 2011 }}</ref>

====Negative publicity====
The laboratory has attracted negative publicity from a number of events. In 1999, Los Alamos scientist [[Wen Ho Lee]] was accused of 59 counts of mishandling classified information by downloading nuclear secrets—"weapons codes" used for computer simulations of nuclear weapons tests—to data tapes and removing them from the lab. After ten months in jail, Lee pleaded guilty to a single count of unauthorized possession of documents, but the other 58 were dismissed with an apology from U.S. District Judge [[James Aubrey Parker|James Parker]] for his incarceration.<ref>

LANSCE provides the scientific community with intense sources of neutrons with the capability of performing experiments supporting civilian and national security research. This facility is sponsored by the Department of Energy, the National Nuclear Security Administration, Office of Science and Office of Nuclear Energy, Science and Technology.
# The National High Magnetic Field Laboratory (NHMFL), Pulsed Field Facility: The Pulsed Field Facility at Los Alamos National Laboratory in Los Alamos, New Mexico, is one of three campuses of the [[National High Magnetic Field Laboratory]] (NHMFL), the other two being at [[Florida State University]], Tallahassee and the [[University of Florida]]'''.''' The Pulsed Field Facility at Los Alamos National Laboratory operates an international user program for research in high magnetic fields.
As of 2017, the Los Alamos National Laboratory is using data and [[algorithm]]s to possibly protect public health by tracking the growth of [[Infection|infectious diseases]]. Digital [[Epidemiology|epidemiologists]] at the lab's Information Systems and Modeling group are using clinical surveillance data, [[Google]] search queries, census data, [[Wikipedia]], and even [[Twitter|tweets]] to create a system that could predict epidemics. The team is using data from Brazil as its model; Brazil was notably threatened by the [[Zika virus]] as it prepared to host the [[2016 Summer Olympics|Summer Olympics in 2016]].<ref>{{Cite news|url=https://homelandprepnews.com/stories/24541-los-alamos-national-laboratory-reveals-potential-tracking-disease-spread-real-time/|title=Los Alamos National Laboratory reveals potential in tracking disease spread in real time|last=Galford|first=Chris|date=October 4, 2017|work=Homeland Preparedness News|access-date=October 11, 2017|language=en-US}}</ref>

==Laboratory management and operations==
Within LANL's 35-square-mile property are approximately 2,000 dumpsites which have contaminated the environment. It also contributed to thousands of dumpsites at 108 locations in 29 US states.<ref name=sf>{{cite news|author1=Staci Matlock|title=TRINITY: 70 YEARS LATER 'Los Alamos will never be clean'|url=http://www.santafenewmexican.com/news/local_news/los-alamos-will-never-be-clean/article_a3cc7ce1-8af0-5113-8f38-5d4aa673fd7a.html|access-date=July 18, 2015|work=The Santa Fe New Mexican|date=July 13, 2015}}</ref>

===Contract changes===
Continuing efforts to make the laboratory more efficient led the Department of Energy to open its contract with the University of California to bids from other vendors in 2003. Though the university and the laboratory had difficult relations many times since their first World War II contract, this was the first time that the university ever had to compete for management of the laboratory. The University of California decided to create a private company with the [[Bechtel]] Corporation, [[Washington Group International]], and the [[BWX Technologies]] to bid on the contract to operate the laboratory. The UC/Bechtel led corporation—[[Los Alamos National Security, LLC]] (LANS)—was pitted against a team formed by the [[University of Texas System]] partnered with [[Lockheed-Martin]]. In December 2005, the Department of Energy announced that LANS had won the next seven-year contract to manage and operate the laboratory.{{citation needed|date=July 2015}}

On June 1, 2006, the University of California ended its sixty years of direct involvement in operating Los Alamos National Laboratory, and management control of the laboratory was taken over by [[Los Alamos National Security, LLC]] with effect October 1, 2007. Approximately 95% of the former 10,000 plus UC employees at LANL were rehired by LANS to continue working at LANL. Other than UC appointing three members to the eleven member board of directors that oversees LANS, UC now has virtually no responsibility or direct involvement in LANL. UC policies and regulations that apply to UC campuses and its two national laboratories in California ([[Lawrence Berkeley National Laboratory|Lawrence Berkeley]] and [[Lawrence Livermore National Laboratory|Lawrence Livermore]]) no longer apply to LANL, and the LANL director no longer reports to the UC Regents or UC Office of the President.{{cn|date=April 2024}}

On June 8, 2018, the NNSA announced that Triad National Security, LLC, a joint venture between [[Battelle Memorial Institute]], the University of California, and Texas A&M University, would assume operation and management of LANL beginning November 1, 2018.<ref>{{cite news |author=National Nuclear Security Administration |date=2018-06-08 |title=NNSA awards Los Alamos National Laboratory Management & Operating Contract |url=https://www.energy.gov/nnsa/articles/nnsa-awards-los-alamos-national-laboratory-management-operating-contract |location=Washington, D.C. |access-date=2018-07-29 }}

===Safety management===

In August 2011, the close placement of eight plutonium rods for a photo nearly led to a criticality incident. The photo shoot, which was directed by the laboratory's management, was one of several factors relating to unsafe management practices that led to the departure of 12 of the lab's 14 safety staff.<ref>{{Cite web |date=2021-03-28 |title=A near-disaster at a federal nuclear weapons laboratory takes a hidden toll on America's arsenal |url=https://www.science.org/content/article/near-disaster-federal-nuclear-weapons-laboratory-takes-hidden-toll-america-s-arsenal |language=en |doi=10.1126/science.aan7026}}</ref> The criticality incident was one of several that led the Department of Energy to seek alternative bids to manage the laboratory after the 2018 expiration of the LANS contract.<ref name=sciencemag-20180119/>

LANL surveys the air, soil, sediment, groundwater, and surface water surrounding the Laboratory to ensure that contaminants from these operations do not pose problems to workers or the public. LANL contracted with Locus Technologies to build its Intellus NM database to make the results of environmental monitoring activities accessible to the public.<ref>{{Cite web |title=Intellus New Mexico - Los Alamos Area Environmental Data |url=https://www.intellusnm.com/home/about_intellus.cfm |access-date=2025-09-23 |website=www.intellusnm.com}}</ref><ref>{{Cite web |title=Science X Network :: Phys.org, Medical Xpress, Tech Xplore |url=https://sciencex.com/wire-news/94890805/los-alamos-national-laboratorys-environmental-data-now-viewable.html |access-date=2025-09-23 |website=sciencex.com}}</ref><ref>{{Cite web| title=Improving Public Communication through Environmental Data Transparency at Los Alamos National Laboratory – 15306 | url=https://archivedproceedings.econference.io/wmsym/2015/papers/15306.pdf | archive-url=https://web.archive.org/web/20250128010018/https://archivedproceedings.econference.io/wmsym/2015/papers/15306.pdf | archive-date=2025-01-28}}</ref>

==Extended operations==
{{unreferenced section|date=July 2015}}
With support of the [[National Science Foundation]], LANL operates one of the three [[NHMFL|National High Magnetic Field Laboratories]] in conjunction with and located at two other sites [[Florida State University]] in [[Tallahassee, Florida]], and [[University of Florida]] in [[Gainesville, Florida]].

Los Alamos National Laboratory is a partner in the [[Joint Genome Institute]] (JGI) located in [[Walnut Creek, California]]. JGI was founded in 1997 to unite the expertise and resources in [[genome project|genome mapping]], [[DNA sequencing]], technology development, and [[information science]]s pioneered at the three [[genome]] centers at University of California's [[Lawrence Berkeley National Laboratory]] (LBNL), Lawrence Livermore National Laboratory (LLNL), and LANL.

The '''Integrated Computing Network''' (ICN) is a multi-security level network at the LANL integrating large host supercomputers, a file server, a batch server, a printer and graphics output server and numerous other general purpose and specialized systems. [[IBM Roadrunner]], which was part of this network, was the first supercomputer to hit petaflop speeds.<ref>{{cite news |url=http://uk.reuters.com/article/technologyNews/idUKN0947487420080610 |archive-url=https://web.archive.org/web/20080929232637/http://uk.reuters.com/article/technologyNews/idUKN0947487420080610 |url-status=dead |archive-date=September 29, 2008 |title=Energy Dept says new computer world's fastest |last=Fox |first=Maggie |work=[[Reuters]] |date=June 9, 2008 |access-date=March 4, 2016}}</ref>

Until 1999, The Los Alamos National Laboratory hosted the [[arXiv]] e-print archive.<ref>{{cite news |url=http://www.nature.com/nature/debates/e-access/Articles/ginsparg.html|title=Los Alamos loses physics archive as preprint pioneer heads east.|date=June 5, 2001 |access-date=March 4, 2016}}</ref> The arXiv is currently operated and funded by [[Cornell University]].

The [[coreboot]] project was initially developed at LANL.<ref>{{cite web|url=https://www.coreboot.org/FAQ#Who_is_working_on_coreboot.3F|title=FAQ - coreboot|website=www.coreboot.org}}</ref>

In the recent years, the Laboratory has developed a major research program in [[systems biology modeling]], known at LANL under the name q-bio.

In November 2008, a drum containing nuclear waste was ruptured due to a '[[deflagration]]' according to an [[Office of Inspector General (United States)|inspector general]] report of the Dept. of Energy, which due to lab mistakes, also occurred in 2014 at the [[Waste Isolation Pilot Plant]] near [[Carlsbad, New Mexico]] with significant disruptions and costs across the industry.<ref>Wald, Matthew L.

The investigation found that the "missing plutonium" was a result of miscalculation by LANL's statisticians and did not actually exist; but the investigation did lead to heavy criticism of the laboratory by the DOE for security flaws and weaknesses that the DOE claimed to have found.<ref>
