Abstract

A radio frequency quadrupole (RFQ) is considered as a main accelerator of the helium beam irradiation system for the power semiconductor in Korea Multipurpose Accelerator Complex (KOMAC) The RFQ was designed to accelerate the He2+ beam up to 4 MeV with 10 mA peak beam current. We chose a vane type RFQ with 200 MHz operating frequency. The RFQ will be operated with the frequency tracking mode supplied by the digital low level RF control system. In this paper, the design of the 4 MeV RFQ is presented and the beam irradiation system including RF system, control system, utility system, is discussed.
