Stable Beams

High-precision heavy-ion beams ranging over all possible elements, from hydrogen to uranium, can be accelerated to energies as high as 18 MeV per nucleon and delivered to many different experimental end stations.

Each year ATLAS delivers a broad range of beams to meet the needs of Users. Below are examples of recent years. For more information on what beams, energies, and intensities are available, please contact the ATLAS User Liaison.

Beam species for fiscal year 2018 as a percentage of beam hours delivered.

The maximum energy quoted corresponds to the computed with the optimal charge state. Higher energies are possible by using another charge state or by double stripping. 

a Other isotopes available with currents proportional to their abundance. For more beam current isotopically enriched material may be used, but the User should, in general, contact the User Liaison or ATLAS Operations to check on the availability of enriched material.

b Indicates elements for which isotopically enriched material has been successfully used in the past.

c Allowed maximum radiation may limit beam current.

The maximum energies in Area II are about 0.6 times these values.
