Transverse beam dynamics studies in the FRIB accelerating cryomodules

The accelerating segments in the Facility for Rare Isotope Beams (FRIB) linac contain superconducting RF cavities accelerating the beam and superconducting solenoids providing transverse focusing. We have studied the transverse emittance growth in the post-stripper linear accelerating segment of the FRIB linac. To understand the cause of the emittance growth we employ a macroparticle tracking code to simulate 3D beam dynamics in this segment of the linac. The model is being developed and validated by beam measurements. The measurements are focused on the response of the transverse beam position along the segment after the beam is kicked by dipole steering magnets at the entrance to this segment. The results of the studies with various beam species and energies will be presented.
