A superconducting linac is developed at KOrea Multi-purpose Accelerator Complex (KOMAC) for proton beam energy upgrade from 100 MeV to 200 MeV. The SRF linac consists of thirty-six half-wave resonator (HWR) cavities. 350 MHz, β = 0.56 HWR is designed to provide 3.6 MV accelerating voltage. After a fundamental RF design study, an analysis on a multipacting (MP) of HWR is carried out. The MP simulation for the HWR is performed by using CST Particle Studio. To understand a feature of the MP occurrence in the HWR, a particle-in-cell simulation is conducted while changing various conditions such as an RF amplitude, an RF phase, and an emission surface.

A proton beam irradiation system for space part test has been developed at Korea Multi-purpose Accelerator Complex (KOMAC) based on 100 MeV proton linac. It consists of a thermal vacuum chamber, a beam diagnostic system and a control system in the low flux beam target room. The thermal vacuum chamber accommodates the capacity for proton beam irradiation in addition to temperature control in vacuum condition. The beam diagnostic system is newly installed to measure the lower dose rate than existing one. In this paper, the proton beam irradiation system for space part test including a thermal vacuum chamber, newly installed beam diagnostic system is presented.
