Prototype Valve Box, Uppsala meeting, 14-15th April 2015

2. 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…

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

4. 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

5. 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

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