High average power rf window study
WebThe window transmitted 75 kw of power without evidence of breakdown or change of electrical characteristics. Interna arcing occurred in the ring resonator at the 75 kw level. … Web1 de out. de 2024 · This paper describes an effective cooling-design approach to the elimination of the RF-induced frequency-shift in the resonant cavity of the Radio Frequency Quadrupole with the high average-power operation. After the RF power is fed into the cavity, the frequency may shift due to the temperature change in the cavity.

Web17 de out. de 2024 · To calculate the peak power, divide the average power by the duty cycle. What is a RF Average Power and Peak Power? Definition: Peak power is the … WebTests on the final window resulted in a voltage standing-wave ratio (VSWR) in the range 1.01 to 1.03. Windows of this type used on four linacs have operated satisfactorily. Finally, windows which have failed were punctured at a power of about 4 Mw when a magnetron drifted off frequency and produced a large VSWR with a high voltage at the window.
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. Web20 de ago. de 1998 · On the APT accelerator there will be over 1,000 windows, each passing on the order of 250 kW of CW RF power. This power level is well above power levels historically used in RF windows. Based on the high-power RF test results of the RF window prototypes from vendors, the coaxial windows made by EEV Ltd. of …

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
WebOver the past year Advanced Energy Systems Inc has undertaken a program to develop CW High Power RF windows utilising a unique fabrication approach. Our fabrication approach should result in a window that inherently places low stress on the ceramic. The design will provide for excellent cooling of the ceramic, which when combined with the use of a …
