Beam dynamics modeling of the proton RFQ MEBT with CST Particle Studio
- Los Alamos National Lab. (LANL), Los Alamos, NM (United States)
Beam dynamics in the Medium-Energy Beam Transfer (MEBT) after the new proton RFQ for the LANSCE injector is modeled with the CST Particle Studio PIC solver. The modeling uses the CST-calculated 3D EM fields of MEBT elements, which is important because (i) the beam size in MEBT is large, comparable to the beam-pipe aperture, and (ii) the fields of neighboring MEBT elements overlap. Our results indicate significant beam emittance growth not predicted by traditional beam dynamics codes.
