THE RF PHASE AND AMPLITUDE MONITORING SYSTEM OF THE VEPP-5 PREINJECTOR

The VEPP-5 500 MeV preinjector has some 2856 MHz power klystrons and others RF devices to drive the accelerating modules. The amplitude and phase control of the RF power for the energy doubler device (SLED) and for the preinjector accelerating section is necessary. The system of the RF parameters manipulation and of the precision monitoring is created. A description of this system parameters and architectures, of the available diagnostic tools and of the experimental results is given.
