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.
