Multipacting Simulation and Analysis for the FRIB FRIB B=0.085 Quarter Wave Resonators Using Track3P.

摘要

The driver linac for the Facility for Rare Isotope Beams (FRIB) utilizes several types of low-a superconducting resonators to accelerate the ion beams from 0.3MeV per nucleon to 200MeV per nucleon. Multipacting (MP) is an issue of concern for such superconducting resonators as they have unconventional shapes. We have used the parallel codes Track3P and Omega3P, developed at SLAC under the support of the DOE SciDAC program, to analyze the multipacting barriers of such resonators. In this paper, we will present the simulation results for the a(v/c) = 0.085 Quarter Wave Resonator (QWR) for the FRIB project. Experimental data will also be presented to benchmark with the simulation results.
