Analysis of residual activity at the FRIB linear accelerator

The Facility for Rare Isotope Beams (FRIB) is an accelerator facility being established at Michigan State University (MSU). The facility will utilize a broad range of primary ion beams from ¹⁶O to ²³⁸U with a beam power of up to 400 kW and energy of 200 MeV/u for ²³⁸U in its baseline configuration to produce rare isotopes. A possible facility upgrade will include an increase of the beam energy up to 400 MeV/u for ²³⁸U and addition of new light ion beams down to ³He and protons for Isotope Separation Online (ISOL) operations. The FRIB double-folded linear accelerator will accommodate several high-rate beam loss devices. The residual activity of these devices were analysed and results are presented in this work. (paper)
