New design studies
Optimisation
General issues
• passage of services for the vacuum equipment
• shielding modifications to accommodate the vacuum valves
• handling/exchange scenarios (possible conflict with the detector opening scenario)
• operation of vacuum valves in the magnetic field
• 3x stronger magnetic field + irradiated system parts (remote maintenance)
• defined distance for operator (remote handling)
Impact of radiation to personnel
Space
Intervention improvement (hand/remote)
Weight
System robustness (preventive maintenance)
BPM together with ‘Q1TAS’ equipment moved to UX
Vax issues
• convenient design for remote handling
quick flange maintenance scenario
bellows
seals
patch panel
sensor redundancy

New design - Issues
M. Raymond –19th WP8 meeting –
Standard Opening configuration
Run configuration
Handling device conflict
Lifting devices enter JFC3 (20mm/10mm)
Valve actuator enters JFC3 (20cm)
Beam pipe support/box conflict
When solved – provided envelope dimensions for VAX module

Solenoid coil vs. Magnetic field (1)
Gate valve magnetic test
Aim:
Influence of magnetic field on solenoid coil of 4/2 way valve
Tested object:
Vat Valve Series 47
DN63
Place and data:
EHN hall (building 887, MNP22 (max 660 [mT])
Participants:
Jaime Espinos, Willemjan Maan, Lukasz Krzempek 1 2 3
Configuration 1&2 – solenoid coil reacts at about 350 [mT]
– no influence on position indicator and other parts
Configuration – no reaction if the same direction of magnetic field with the dipole’s one
– solenoid coil reacts when opposite direction (around 80 [mT])
External magnetic field does have the influence on the behaviour of powered valve solenoid

Position indicator vs. Magnetic field (2)
Set up ready for tests in M1 magnet in H2 Test Beam Area (max 3 [T]).
End of May/June as envisaged time to run M1 magnet.
