Design of High Power Microwave Ceramic Windows in C-Band

WebPurpose: To study the role of temperature in biological systems, diagnostic contrasts and thermal therapies, RF pulses for MR spin excitation can be deliberately used to apply a thermal stimulus. This application requires dedicated transmit/receive (Tx/Rx) switches that support high peak powers for MRI and high average powers for RF heating. WebRecently, the main focus at PITZ has been the study of gun reliability and photoinjector performance at high average power. The goal is to get stable and reliable operation with 6.4 MW peak power in the gun at 650 μs RF pulse length and 10 Hz repetition rate. To achieve this, a new RF feed system with two RF windows was installed at PITZ in 2014.

WebRF gun has to operate with long RF pulses. Generating high beam quality from the photo-cathode RF gun in addition requires a high accelerating gradient at the cathode. Therefore, the RF gun has to ensure stable and reliable operation at high average RF power, e.g. 6.5 MW peak power in the gun for 650µs RF pulse length and 10Hz Webhigh induced stress. Such thermo-mechanical effects will ultimately limit the average power that can be propagated by an RF window. Presented here will be results of processing experience with four waveguide windows manufactured by Thomson Tubes for 500ÊMHz operation up to 500ÊkWCW traveling wave. These
