Design studies for the Proton-Linac RFQ for FAIR — •Markus Vossberg, Robert Brodhage, Michael Kaiser, Fabio Maimone, and Wolfgang Vinzenz — GSI, Darmstadt

The planned 26 m long Proton-Linac (P-LINAC) for FAIR (Facility for Antiproton and Ion Research) comprises a RFQ (Radio-Frequency Quadrupole) and 6 CH-cavities to accelerate a 70 mA proton beam up to 70 MeV. The FAIR Proton-Linac starts with a 325.2 MHz, from 95keV to 3 MeV RFQ accelerator. The main RFQ for this Proton-Linac will be a 4-Vane RFQ. Beam dynamics designs with varying and constant transverse focusing strengt for the electrode parameters will be used. CST simulations will help to find cavity parameters for the working frequency. This paper presents the main cavity designs concepts and CST simulation results.
