The first Mitsubishi Electric Co. Linac type ML-15M was installed in 1970. Maintenance and reliability of the equipment have been examined for seven years. Thirty percent of the troubles happend immediately after installation. Another thirty percent were caused by the superannuation of the parts. Average Klystron life was 3813.9 hours which was three or four times longer than Magnetron. Rate of troubles was under 0.5 PCT per hour. Operation rate constantly over 96 PCT is satisfactory. A distribution chart for each tumor treated by Linac was also presented.
