A feedback system to stabilize a long-time operation of thermionic cathode RF-Gun has been developed in Kyoto University free electron laser (KU-FEL) facility where a 4.5-cell thermionic cathode RF-gun provides electron beam to drive a mid-infrared FEL. Since the backbombardment effect seriously increases the temperature of the cathode surface and, consequently, increases the beam charge, a stable operation is difficult without continuous control of the thermal emission from the cathode.
