Argonne Tandem Linac Accelerator System

ATLAS
The prime national facility for nuclear structure research. The Argonne Tandem Linac Accelerator System (ATLAS) is the world’s first superconducting linear accelerator for heavy ions at energies in the vicinity of the Coulomb barrier.

COVID-19 Update - June 1, 2021

Dear ATLAS User Community,

In line with guidance from the U.S. Centers for Disease Control and Prevention, the Occupational Safety and Health Administration, and the U.S. Department of Energy, Argonne National Laboratory is relaxing some on-site COVID-19 controls, effective Tuesday, June 1, 2021:

  • Fully vaccinated Argonne employees no longer need to wear a face covering or socially distance on site. An individual is fully vaccinated two weeks after their final vaccine dose. 
  • Fully vaccinated ATLAS users no longer need to wear a face covering on site. Proof of vaccination may be asked for, from you or your employer, by Argonne management if there is a need to know. 
  • Non-vaccinated employees and ATLAS users must continue to wear a face covering and maintain six feet of distance from co-workers while on site.
  • Although social distancing is not required for people who are fully vaccinated, Argonne is still recording the time that people are in close proximity in case an issue arises where contact tracing is necessary. Therefore, wearable proximity devices will continue to be assigned for this purpose until further notice.

This is the energy domain best suited to study the properties of the nucleus, the core of matter and the fuel of stars. ATLAS can provide beams of essentially all stable isotopes from protons to uranium, and a variety of light radioactive beams through our in-flight production program and heavier neutron-rich isotopes from CARIBU.

ATLAS is a U.S. Department of Energy User Facility that hosts roughly 200 to 300 users each year. It is supported by the Office of Nuclear Physics of the Department of EnergyATLAS users come from U.S. universities and national laboratories as well as from foreign institutions. The facility is also accessible to industrial users.
