6th srf collaboration meeting @ lasa 13 June 2017 - CAVITY interfaces - Vincent Hennion / PIERRE BOSLAND Bonjour, Franck Peauger, Je suis Ingénieur RF accélérateurs au SACM Je suis au CEA depuis janvier 2006

Two types of interfaces Internal interfaces: Cavity with helium tank welded, equipped with flanges, brackets (on tuner), pick-up antennas and vacuum valve Interfere closely with cold tuner, MLI, magnetic shielding, cavity support, intercavity below / cold warm transitions and cryogenic lines External interfaces: Vacuum vessel fully equipped Connectors of instrumentation fixed on the cryomodule (for its vacuum integrity) Interfere with warm-units, waveguides, cryomodule supports, valve box, auxiliary lines, exhaust lines, isolation vacuum pumping systems, cables for instrumentation 13/06/2017 Technical interfaces
