VSC consolidation – Beam Vacuum (1) 1. Eliminate critical PIM Ø Corrective action: ~14 q Ball tests localization of buckled fingers and finger exchange q Endoscopic inspections Ø Preventive consolidation (TETM, 17/01/2011) q Arc extremities : 18 q Magnet exchanges: 18*4 q Damage bellows: ~10 Cédric Garion TE/VSC Beam Vacuum Quality Control AL 4030, 15 Jan‘ 13
VSC consolidation – Beam Vacuum (1) Simplified PIM consolidation sequence: Work is done in collaboration with the Special Intervention Team (SIT) 1. Ball test (TE/VSC & BE/BI) 2. Interconnection opening (SIT) 3. 4. 5. 6. 7. Beam line cutting (SIT) Dummy PIM installation PIM reconditioning (VSC) // Lip measurements* (ICIT) // Endoscopy (ICIT) PIM positioning, tack welding and PIM bellows protection (VSC) PIM welding (SIT) 8. Beam line leak test (VSC) 9. Ball test (VSC) * Required for PIMs at magnet exchanges and for damaged bellows In case of buckled RF fingers, the same PIM body is re-installed at the same location (PIM WG, 2/12/08) Cédric Garion TE/VSC Beam Vacuum Quality Control AL 4030, 15 Jan‘ 13
VSC consolidation – Beam Vacuum (2) 2. Protect against overpressure: Ø Install rupture disks and non-return valves Ø Install protective shells to limit the bellows deformations 3. Protect against electrical arcs and melted particle projection Ø Install protective shells (PEI) Cédric Garion TE/VSC Beam Vacuum Quality Control AL 4030, 15 Jan‘ 13
VSC Support – Interconnection QC Check integrity of bellows: Ø Beam screen, PIM and X line bellows Ø Visual inspections of bellows after opening and before closure Ø Installation of temporary protections in place throughout the period during which the interconnections are open: rubber strip + stainless steel foil Additional protections (1 protective half shell per line) will be installed during (at least) the cutting activities. Cédric Garion TE/VSC Beam Vacuum Quality Control AL 4030, 15 Jan‘ 13
VSC Support – Beam Vacuum (2) Opening/closure and inspection/protection sequence: 1. Interconnection opening (MSC): W bellows, thermal and radiative shields 2. Rubber protections on V 1, V 2 and X bellows (MSC) 3. M bellows shell dismounting (MSC) 4. Interconnection inspection and thermometers disassembly (ICIT) 5. Rubber protection removal and bellows inspection (ICIT) 6. Rubber and stainless steel foil protection installation (ICIT) 7. Installation of additional dedicated protective half shell before the cutting train and removal after ~1 week (recycling) (ICIT) 8. Beam vacuum line leak tests (VSC) 9. Temporary protection removal and bellows inspection (ICIT) 10. Installation of permanent protective half shells (ICIT) 11. Interconnection inspection and thermometers assembly (ICIT) 12. M bellows shell assembly (MSC) 13. Interconnection closure (MSC) Cédric Garion TE/VSC Beam Vacuum Quality Control AL 4030, 15 Jan‘ 13
VSC Support – Beam Vacuum (3) Inspection work flow: Ø The status of existing non-conformities is available (based on EDMS data) Expected state 2 nd inspection: state conformed to expectations 1 st inspection: state conformed to expectations Yes No No NC opening NC follow up (if exists): to cut or not to cut? Visual localisation of damage, if any, and protections NC follow up: to cut or not to cut NC closure Delete of damage localisation marks, Installation of the protective half shells Other activities: splice, leak tests, ELQA, … Cédric Garion TE/VSC Beam Vacuum Quality Control AL 4030, 15 Jan‘ 13
