08.05.2015 3 Lukasz Krzempek, TE-VSC-DLM 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 08.05.2015 3 Lukasz Krzempek, TE-VSC-DLM

Raymond –19th WP8 meeting – 28.04.2015 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 Detailed design of VAX module 08.05.2015 5 Lukasz Krzempek, TE-VSC-DLM

08.05.2015 6 Lukasz Krzempek, TE-VSC-DLM 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]) 08.04.2015 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 3 – 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 08.05.2015 6 Lukasz Krzempek, TE-VSC-DLM
