Functional interfaces ESS Spoke Cryomodules Prototype Valve Box Space requirements Functional interfaces Prototype Valve Box, Uppsala meeting, 14-15th April 2015

Design Status Detail drawings of the valve box are under progress… (VV, support frame, jumper, cryogenic circuits, vacuum barrier…) → last call to change the color of the external paint…

Space Requirements A little less than : 3x3x3 m3 About 3 tons (to be confirmed)

CTS (tuner) maintenance Dedicated tooling aim at: Space Requirements CTS (tuner) maintenance Dedicated tooling aim at: supporting the valve and the small end dish Dismantling : Large dish end of the VV MLI and Thermal shield

Procedure, crane and manpower useful « Deluxe » version: 5m length CTS maintenance Total length for access on one side only: 3.9 m Procedure, crane and manpower useful Access: 800mm for CTS maintenance « Deluxe » version: 5m length

Vacuum interfaces Cryomodule Valve Box HV GATE Valve (VAT, ISO-F DN 100) Valve Box Same HV GATE Valve (VAT, ISO-F DN 100)

Localisation of the instrumentation « towers » x2 (ISO KF DN50)

RF interfaces half size WR2300 wave guides For Uppsala: Possibility to rotate the doorknobs by 180° ESS Configuration half size WR2300 wave guides

Cryo-fluids interfaces From ICB From ICB To Reheater To Reheater Supply of saturated liquids: LHe : - FREIA: 1.2 bara IPNO: 1.2 bara LN2 : - FREIA: 3 bara IPNO: 1.5 bara max Vapours exhausts: He : - VB phase separator: 5 K ; Patm - Pumping line: 5 K ; subatm N2 : 90-110 K : Patm (TBC?)

Cryoliquids interface From IPNO facilities: 2 x bayonets From FREIA facilities: HNOOS type: 2xVCR (VV and TS sleeves removed) LHe LN2 VV sleeve TS sleeve

Vapours interface Interfaces compatible for both IPNO and Freia facilities He pumping line ISO-F DN 100 (bayonet) He exhaust KF DN 40 (bayonet) N2 exhaust KF DN 40 (bayonet)

Cooling Water for power coupler Ceramic window Coupler antenna More details after the prototype assembly at Orsay (best localization of the interconnections, easiest access…) Compressed Air for gate valve actuators
