Design of rod-type high current proton radio frequency quadrupole accelerator for ANURIB project @ VECC

A high current rod type RFQ accelerating protons to 1 MeV has been envisaged as the injector to 50 MeV proton driver for the ANURIB facility. This would be used to produce p-rich radioactive nuclei complementing the n-rich nuclei production via the photo fission route. Rod type structure has been chosen owing to ease of machining and well separated dangerous dipole modes appearing in vane type structures, This paper will describe the beam dynamics design of 5 mA proton beam through the RFQ, starting from efficient physical parameter optimization followed by corroborative studies using tracking codes. Preliminary RF structure of 80 MHz RFQ would also be presented. (author)
