Abstract:
The SRF cavities for the electron storage ring of an Electron-Ion Collider (EIC) to be built at BNL require CW high power couplers with variable Qext. The approach taken to develop this coupler was to leverage an existing 500 kW CW fixed coupler design, and implement the coupling adjustment by means of a waveguide tuner section adjacent to the coupler. This talk will briefly present the R&D approach and progress to date including design choices, fabrication and results of the initial high power testing of the couplers which were recently completed, and plans of high power couplers for BNL EIC applications.
Provocative Topics:
High power coupler adjustment via waveguide tuner with a fixed coupler; challenging performance requirements for the BNL EIC electron storage ring SRF system; high power test results with lessons learned and plan moving forward.
