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.

Coronavirus Update - June 28, 2020

On June 15, Argonne started a phased, coordinated process to return to normal operations. The first phase of the transition—limited operations— restarted a select number of additional activities at ATLAS on June 23.

In this phase, ATLAS will be restarting operation with minimum on-site staff to perform high-priority PAC-approved experiments that can be carried out without the on-site presence of outside users. ATLAS will operate on a limited five days a week schedule during this transition period. An updated schedule for experiments will be posted as soon as possible and provisions are being taken to simplify remote monitoring of experiments.

As the public health situation improves, Argonne will eventually move to the next stages of operations. For a visual representation of our phased approach to normal operations, visit https://​anl​.box​.com/​s​/​i​o​s​r​42​t​12​t​h​5​u​s​9​q​y​3​d​45​f​u​8​j​f​8​ro89p.

The health and safety of our employees, users, students and visitors remains our top priority. As the public health situation improves, Argonne will eventually move to subsequent phases, which will bring more user activity back onsite. We will continue to monitor and adapt to changing conditions onsite, in the surrounding communities, in our state and nationwide. We will move forward, or back, across phases as needed as the situation evolves.

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.
