In situ Measurements of the SPS 200MHz Accelerating Cavity III

The main 200MHz travelling wave RF system of the SPS consists of two 5-tank and two 4-tank cavities. This system will be modified during LS 2, and the preparation work has already started. The 5 tank 200MHz travelling wave cavity III was measured in reflection. This Internal Note presents results ob...

Sumario:The main 200MHz travelling wave RF system of the SPS consists of two 5-tank and two 4-tank cavities. This system will be modified during LS 2, and the preparation work has already started. The 5 tank 200MHz travelling wave cavity III was measured in reflection. This Internal Note presents results obtained for the matching of cavity and feeder line, by looking at both frequency and time domain data. Techniques for estimating the feeder line attenuation are also presented.
