BEAM SIMULATIONS FOR THE MSU-RIA DRIVER LINAC USING IMPACT CODE*

Previous beam dynamics simulation studies using LANA code at Michigan State University (MSU) including alignment and rf errors and the effect of the charge strippers have indicated that the Rare Isotope Accelerator (RIA) driver linac proposed by MSU has adequate transverse and longitudinal acceptances to accelerate light and heavy ions to final energies of ≥400 MeV/u with beam powers of 100 to 400 kW [1]. Recently, the beam dynamics simulation studies for the driver linac were performed with the IMPACT parallel code on the high performance computers at MSU. IMPACT [2] code was first benchmarked with LANA [3] code, and the results from the two codes are in good agreement. IMPACT has then been used for beam simulations, especially for high statistics evaluations. In this paper, we present the results of the beam dynamics studies using IMPACT code
