FRIB and Los Alamos National Laboratory

High-intensity proton ion source

Los Alamos National Laboratory (LANL) provided the ion source that allowed FRIB to successfully demonstrate the performance of the liquid lithium charge stripper.

FRIB borrowed a high-intensity low-energy demonstration accelerator (LEDA) proton ion source from LANL to test the performance of the liquid-lithium demonstration film developed at Argonne National Laboratory. The goal was to deposit on the lithium film a beam with similar power densities as will be encountered with FRIB’s uranium beams.

The ion-source beamline was modified to interface with the ANL lithium installation and to obtain a small spot at the position of the lithium film.
