Oral

I will present the the issues that we encountered and ultimately overcame while testing and commissioning our new 300kW class klystron. Issues such as unexpected mod-anode PS ripple frequencies, HV electro-static shielding, correct biasing of the mod-anode electrode during a fast HV fault, HV turn-on transients, filament resistance changes, etc.

Oral

Last year we celebrated the 10th anniversary of commissioning the Swiss Light Source. The heaters of all klystrons collected about 255’000 hours during this time and the overall operation was extremely successful. Nevertheless several issues, like reinforcing the HV cabinet, coincident arc detection and cooling air interlock had to be improved. These klystrons are not any longer produced by...
