Detailed Cavity Design for the FAIR p-Linac — •Ali Almomani1, Ulrich Ratzinger1, Marco Busch1, Rudolf Tiede1, and Florian Dziuba2 — 1IAP - Frankfurt University — 2GSI - Darmstadt
The research program of antiproton beams for the FAIR facility requires a dedicated 70 MeV, 70 mA proton injector. This injector will consist of a ladder RFQ and followed by six room temperature "Crossbar H-type" CH-cavities operated at 325 MHz. The MEBT section behind the RFQ has been optimized for beam matching into the CH-DTL. The beam dynamics for the DTL had been revised to reduce the emittance growth. As a consequence cavity voltage, gap numbers, lens layouts, and cavity end geometry were optimized. Consequently, the construction of cavities can be started in 2017. In this paper, the detailed design of these cavities with integrated focusing triplets will be presented and the main issues will be discussed.
