Crab Cavity HOM Coupler Design & Fabrication Review II
→
US/Eastern

Description
This review is to assess the readiness for fabrication of the HOM couplers and high pass filters for the two designs of the Crab Cavities for the HL-LHC and will be used in the validation tests in the SPS.
We will cover the fabrication, assembly, surface preparation and tuning plans for each device, including eventual high power conditioning. Comments on the electromagnetic designs following the internal review held in December will also be presented.
A no host dinner will be organized in the evening for those who are staying overnight and all locals who are available to join
