18. Power Coupler Interfaces & RF System

Eric Montesinos (CERN)

13/12/2012, 14:00

The power coupling schemes for the three cavities are reviewed for the nominal and maximum power flow and suitable common platform vacuum to air interface is proposed. The interfaces to the RF source and the cryostat is also presented with general layout of the powering system for the SPS tests and initial concepts for the final LHC system.

21. HOM Couplers & Damping

Zenghai Li (SLAC)

13/12/2012, 14:30

The designs of the HOM couplers to be used on the three cavities is reviewed along with their transmission properties. A common platform high pass filter for HOM damping is proposed with the aim of prototyping the coupler and filter stages for warm cavity tests to meet the impedance budget. HOM coupler layout and preliminary heat load estimates are given to compare the complexity of the...

22. Cryogenic Circuit & Heat Loads

Krzysztof Brodzinski (CERN)

13/12/2012, 15:00

2K operation of the SPS BA4 cryogenic system for a crab cavity test in horizontal configuration with two adjacent cavities in a single cryostat. Helium availability, pressure, cryo circuits, safety valves, protection, overall installation effort,cost, time line, maximum heat loads and the impact on the overall SPS/LHC during regular operation is described. Aspects of cryogenic testing in the...
