Status of KURNS-LINAC

Operating time of KURRI-LINAC was 2,784.1 hours in 2017FY, the record high. Nuclear data was 35%, radiation measurement was 21%, radiation damage was 18%, RI manufacturing and activation analysis was 16%, coherent light source was 9%, the percentage of the operating time. Troubles were KURNS – LINAC in 2017FY, the leakage of the cooling water at No.2 klystron, the damage was minimal by experience in the past to the leakage of cooling water, and RF driver was troubled multiple times, the error of indication of the RF output power, the machine stop by reflection power over, and the error of RF output power.
