BGV Integration Vacuum layout G. Bregliozzi – TE-VSC-LBV BGV Meeting #19 11/09/2013

Vacuum Sector A 7 L 4. R Divided in 3 vacuum sectors • C 7 L 4. R: Q 7 (ARC) Side • B 7 L 4. R: For the BGV installation • A 7 L 4. R: Q 6 Side Q 7 C 7 L 4. R ≈30 m B 7 L 4. R A 7 L 4. R ≈30 m A 7 L 4. B Q 6

Simplified layout for the B 7 L 4. R sector

Pressure Profile around the BGV Neon injection

Detailed changes in the layout

New vacuum sector C 7 L 4. R • Need to install: • VGI (ionization) gauge - VSC Stock • All metal DN 63 valve for the pump down and bake-out - VSC Stock • VGRB (pirani) gauge - VSC Stock • Exchange vacuum module VMAAB. E 7 L 4. R in DCUM 9758. 26 with a VAMVD (For the it will be installed at 180 )

New vacuum sectorization for the BGV Vacuum sector 2 x VAEHL Sector valve assembly 4 VGPB (Penning gauge) – VSC Stock 2 VPIA (Ion pump) – VSC Stock 4 x Bellow modules – To be ordered 2 VGRB – VSC Stock 2 all metal valves – VSC Stock 2 Sector valve – Ordered 2 Support - To be ordered
