Abstract: The TRISTAN superconducting RF system has been operated since 1988. The remaining operational problem is the trip of the cavity caused by synchrotron radiation. In order to reduce the trip rate, we made realignment of Q-magnets in the straight section and put a movable radiation mask near the end of the are section. The effect of these improvement, operating status and long term performance are reported. >
