Description
All high power, klystron based, RF systems at ESS rely on high power loads and circulators to protect the klystrons from excessive reflected power and to enable full power testing of the full amplifier chains. The high power testing of the system have revealed significant technical issues with the load design, resulting in damage and poor performance. We report on the high power investigations carried out at ESS with support from the load manufacturer. This talk will describe the key technical challenges and the technical solutions, which are being adopted, and will report on the results of tests with the the prototype mitigations in place.
