Beam dynamics studies in SPIRAL 2 linac

The proposed LINAG driver for the SPIRAL 2 project aims to accelerate a 5-mA D/sup +/ beam up to 20 A.MeV and a 1-mA beam for q/A=1/3 up to 14.5 A.MeV. It is a continuous wave regime (cw), designed for maximum efficiency in the transmission of intense beams. It consists of an injector (two ECR sources+a radio frequency quadrupole) followed by a superconducting section based on an array of independently phased cavities. This paper presents beam dynamics studies associated to the LINAG driver. End-to-end simulations (low-energy beam lines, RFQ, medium-energy beam line, SC linac) are shown.
