1. 6th srf collaboration lasa 13 June CAVITY interfaces - Vincent Hennion / PIERRE BOSLAND
Bonjour,
Franck Peauger,
Je suis Ingénieur RF accélérateurs au SACM
Je suis au CEA depuis janvier 2006

2. 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

3. Cavity Interface drawings
14 different drawings called by the interfaces document including:
7 sheets defining the footprints, dimensions, tolerances, interfaces, and shipment configuration of the cavity:
71 HAAV DM RD sheets 1 to 7
3 for the blind flanges:
71 HAAV DM RD
71 HAAV DM CB
71 HAAV DM RC
One for the bracket clamp:
71 HAAV DM RB (for M-Beta cavity)
71 HAAV DM RB (for H-Beta cavity)
3 for hexagonal aluminum gaskets:
71 HAAV DM RC (vacuum beam tube)
71 HAAV DM RC (coupler)
71 HAAV DM RB (pick-up)

14. Cavity configuration
Optimization of the configuration process and production at CEA
CEA is mastering the configuration of the interfaces documents
Specific needs of STFC not specified by CEA
Important changes to be submitted to CEA through an ESS change request
ESS is in charge of the configuration management of its CATIA folder supplied by CEA, corresponding to the 3D mockup for engineering support given to STFC
