Task 2

High Efficiency Klystron Industrial Prototype

(CERN, Thales, ULAN)

The partners will start from the existing conceptual study of transformation of the TH2167 klystron used for the LHC accelerator at CERN into a high-efficiency unit using the recently developed core stabilisation method. The goal will be to design and build an industrial prototype at higher efficiency (TH2167HE), going from the present 61% efficiency to 71% as predicted by simulations. The klystron will be a drop-in replacement of the existing LHC tube, which provides 300 kW. The high-efficiency version could provide 350 kW using the same infrastructure and the same power supply. It will allow coping with the higher beam intensities of the High-Luminosity upgrade of the LHC without increasing power consumption and it will be a demonstrator of the CSM principle for application in other klystron systems.
