Study on the RF Set Point for the PEFP DTL by using a phase scan method

Abstract

The drift tube linac (DTL) is used to accelerate proton beams from 20 MeV to 100 MeV in the linear accelerator of the Proton Engineering Frontier Project (PEFP). The phase scan signature method is a common technique to determine the radio-frequency (rf) set point, including the rf amplitude and phase, in DTL tanks. In this work, we applied the phase scan method to the first tank of the PEFP’s DTL in order to study the procedure for determining the rf set point by using artificial experimental data generated by using the PARMILA code.
