Investigation of Low Flux Proton Beam at KOMAC for Space Applications

Abstract

Korea Multi-purpose Accelerator Complex (KOMAC) has been operating 20 MeV and 100 MeV proton beam lines to provide proton beams for various applications since 2013. A new beam line with low flux proton has been constructed for simulation of the space radiation-like environment in 2016 and commissioning has been completed in 2017. In this work, we introduced the new proton beam line and reported the results of preliminary proton beam characterization test. As the results, we concluded the new beam line can provide as low as flux of 10 5 #/cm2/pulse, good uniformity within ± 10% and large beam area with wide range of proton energies.
