    Power transmission and distribution
    Talk

    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...

    Talk

    Power variators (PV) or variable attenuators are required to control the RF power transfer to accelerator cavities and to realize dual energy LINACs operated at Megawatt peak power. Dual energy LINACs are used in medical radiation therapy (dual photon energy and imaging mode), as well as in industrial X-ray inspection systems for enhanced material detection in cargo scanning and...

    Control, interlocks, safety
    Talk

    Currently, the radiofrequency (RF) power source to the Argonne Advanced Photon Source (APS) storage ring is under an upgrade from several 1 MW klystrons to solid state amplifiers (SSAs). It is very important to have new interlock systems ready for the new SSA systems. This presentation shares our experience on a new machine protection system (MPS) subsystem development. Other interlock...

    Klystrons
    Talk

    The reliability of Los Alamos Neutron Science Center (LANSCE) 805MHz klystrons used for powering the CCL will be examined and data presented on service hours, post re-build performance and failure points. Reliability and performance of today’s klystrons will be compared with historical data and our current evaluation process will be discussed. Foreseeable problems with current capabilities...
