Calabazas Creek Research, Inc. shipped a 125 kW, C-Band klystron with 18 beams. This is the culmination of an 18-month development program to build a wide-band, low voltage klystron. The tube operates at 25 kV with a bandwidth exceeding 6%. It uses controlled porosity reservoir cathodes and includes an extended interaction output cavity. The klystron is currently being installed for high power testing at the customer’s site.
Life testing of the reflector assembly for CCR’s 1.5 MW CW RF load assembly was terminated on January 3rd after operating for more than 410,000 cycles. The assembly was still operating satisfactorily when the testing was stopped. This is more than twice the expected lifetime for a load in operation at a gyrotron facility. The assembly is being disassembled to determine areas where the design can be improved. These improvements will be implemented to further improve the reliability of the device. The previous post provides a video of the assembly operating in the testing structure.
