1MW 352.2 MHz RF test stand

1 MW, 352.2 MHz CW and pulsed RF test stand has been developed and tested at RRCAT, Indore for performance evaluation and characterization of RF components and accelerating structures. Various power supplies namely one number of high voltage beam bias power supply (-100 kV, 25 A, DC), one number of mod anode power supply (85 kV, 20 mA, DC), one number of filament power supply (20 V, 25 A, DC), two numbers of electromagnet power supplies (300 V, 12 A, DC) and two numbers of ion pump power supplies (5 kV, 10 mA, DC) are employed for operation of this klystron amplifier. Mod anode and filament power supplies of this test stand are floating at cathode potential of -100 kV, 25 A DC and hence suitable high voltage floating platform was developed to house these power supplies. The control and interlock signals are transmitted to these floating power supplies through optical fibres.NI cRIO 9081 controller based real time control system has been installed to operate various power supplies of this klystron amplifier in a particular sequence. It also controls and monitors crucial RF, water flow and temperature parameters of this test stand
