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 -- September 14, 2021

Dear ATLAS User Community,

Starting September 20, users of the Argonne Tandem Linac Accelerator System (ATLAS) will be required to attest to their vaccination status and, if not fully vaccinated, show proof of a negative COVID-19 test result that is less than 72 hours old before they can enter any Argonne site.  

Please note that while Argonne’s policy toward vaccinations is changing, our operational status is not. Argonne and ATLAS remain in limited operations. Masks continue to be required for everyone, regardless of vaccination status, and six-foot social distancing remains in effect.  

Failure by any user to comply with the protocols above will be treated as a safety violation and could result in suspension of the user’s access privileges.

As the COVID-19 pandemic continues to evolve, so does Argonne’s approach to keeping each other safe and healthy so that we can carry out our critical research. Please make sure to verify the latest processes for site access before making plans to travel to Argonne. We appreciate your continued cooperation.

************************************************************************************************

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.
