This paper deals with the control and protection system for electron linac for industrial purposes (KYT). The KYT - a powerful source of accelerated electron beam - is meant for performing various radiation technological processes including sterilization of medical articles. KYT was designed and constructed in KFTI. The pilot KYT has been operating since September 1993. The KYT consists of the electron linac, cooling and control systems. The linac includes the high-voltage generator, electron source, accelerating system, klystron with high-voltage modulator, scanning and electron beam extraction device. This linac produces 8-10 MeV electron beam with power up to 10 kW. Commercial production of KYT is scheduled since 1994. The grounds for choice of protective and control elements of the system are established. To manage operation of the accelerator a control system has been developed, providing for beam current and energy monitoring, control over systems parameters and failure diagnostics. The description of algorithms and results of use of the system is presented.
