  The BIBA (Busan Ion Beam Accelerator) is a compact linear accelerator facility using the 28 GHz ECRIS at the KBSI (Korea Basic Science Institute). Our goal is to generate high current fast neutrons using the heavy ion interaction with a proton target. For a stable operation of the superconducting magnets, the performance of cryostat system is very essential at the 28 GHz ECRIS. However, the emitted x-ray from inner plasma chamber contributes to increase an extra heat load to the cryostat system by absorbing the cold mass of the superconducting magnet. Therefore, we have measured X-ray spectra from the 28 GHz ECR ion source and tried to improve the performance of the Cryostat System by a radiation shielding. In this paper, we will present the test results of X-ray emission on 28GHz KBSI ECRIS and improved cooling system performance.
