Los Alamos National Laboratory

Los Alamos National Laboratory

Delivering science and technology to protect our nation and promote world stability


The Lab's mission is to develop and apply science and technology to ensure the safety, security, and reliability of the U.S. nuclear deterrent; reduce global threats; and solve other emerging national security and energy challenges.


  • Operator
  • Los Alamos National Laboratory
  • (505) 667-5061
Some Lab facilities are available to researchers at other laboratories, universities, and industry.
DARHT accelerator
DARHT's electron accelerators use large, circular aluminum structures to create magnetic fields that focus and steer a stream of electrons down the length of the accelerator. Tremendous electrical energy is added along the way. When the stream of high-speed electrons exits the accelerator it is "stopped" by a tungsten target resulting in an intense burst of x-rays that are used to create digital images of mock nuclear devices as they implode.

Dedicated to national security

The Lab is home to a range of unique facilities, many of which serve dedicated national security missions while others are available to researchers at other laboratories, universities, and industry.

Note: If you are a researcher or collaborator interested in using a facility, continue to the User Facilities area of this website. The list of facilities below is intended to describe the capabilities within the Lab's overall footprint and is not the access point for requesting beam time, submitting proposals, or requesting DOE-designated research opportunities.
