LHC-CC13, 6th LHC Crab Cavity Workshop

9 Dec 2013, 08:30 → 11 Dec 2013, 18:30 Europe/Zurich

30/7-018 - Kjell Johnsen Auditorium (CERN)

Alick Macpherson (CERN), Erk Jensen (CERN), Frank Zimmermann (CERN), Ofelia Capatina (CERN), Rama Calaga (CERN)

A two day crab cavity workshop (LHC-CC13) will be held at CERN, Geneva.  

The main objectives of this workshop are to discuss:

           1. Compact cavity RF test results and performance validation
           2. Cryomodule and RF system development for SM18, SPS tests & LHC
           3. Preparation for the beam tests in the SPS and future roadmap

An additional day on Dec 11, 2013 is reserved for collaboration discussions to develop common standards, specifications, and safety requirements.
