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. 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. ceramic coating for cars in bangalore price
