  1. PGC tests Test procedure and acceptancecriteria for the Powering of Group of Circuits EDMS No 916266

  2. PGC 1 : tests in the arcs PGC 1.2 PGC 1.3 PGC 1.4 PGC1.5 PGC 1.6 S. Le Naour / MP3 meeting

  3. PGC 1 : tests in the matching sections PGC 1.8 PGC 1.9 • Applicable in : •    IP1 - D2, Q4, Q5, Q6 •    IP2 - D2, Q4 •    IP4 - D4, Q5 and D3, RU •    IP5 - D2, Q4, Q5, Q6 •    IP8 - D2 Q4 S. Le Naour / MP3 meeting

  4. PGC 2 : Heatrun S. Le Naour / MP3 meeting

  5. When tests occured 1 : select sector 2 : select circuits (dfb/special) 3 : load T1/T2 4 : start S. Le Naour / MP3 meeting

  6. Tests summaries • Excel files with tests summaryavailable on • Slenaour public/MP3/PGC/Sector12… • MP3 Repository / shared documents/PGC S. Le Naour / MP3 meeting

  7. Tests PGC 1.2 • Ramp up of all circuits available to reach I_PNO at the same time, plateau of several minutes and ramp down of all circuits together • RCS circuits ramp down earlier. • When correctors circuits of triplets are included in the sequence, varioustrippingsoccured due to the too large ramp rate applied: ramp rate reduced to powered RCBXV and RCBXH circuits together S. Le Naour / MP3 meeting

  8. Tests PGC 1.4 • Heaterprovokedquench on the main dipole circuits. • In sector 3-4, only a FPA wasapplied • In sector 1-2, quenchprovoked in C32R1 which have a non conformity on QH1 (2 lowfieldheatersfiredinstead of 1 highfieldheater) • In sector 8-1 : data acquisition pbm on heaterdischarge Global protection activated in all sectorscorrectly S. Le Naour / MP3 meeting

  9. Tests PGC 1.5 • Fast abord on 600A circuits S. Le Naour / MP3 meeting

  10. Tests PGC 1.5 • Fast abord on 600A circuits • Samesequenceapplied in all sectors : • FPA on RCO (40A) RCD (-150A) tripped • FPA on RCS (550A)  no other circuit involved • FPA on RQTL9/10/11 (400A/550A)  no other circuit involved • FPA on RQT12/13 (400/550A)  no other circuit involved • FPA on RQS (2 magnets)  no other circuit involved • FPA on RQS (4 magnets)  RQTD/F, ROD/F, RSD/F1 & 2, RSS tripped • FPA on RSF1 (400A)  RSD/F1 & 2, RSS, ROD/F, RQTD/F, RQS (4 magnets) tripped • Only circuits on the samebeamtripped, no influence between B1 circuits and B2 circuits S. Le Naour / MP3 meeting

  11. Tests PGC 1.5 • Fast abord on 600A circuits ROD ROF RQS S. Le Naour / MP3 meeting

  12. Tests PGC 1.8 • Current cycles in matching section circuits • Tests often/always made with PGC 1.2 • Nothingspecial to report S. Le Naour / MP3 meeting

  13. Tests PGC 1.9 • FPA on SC separationdipole • Whenquenchheatersfired in RD, ramp down of all other IPD, IPQ involved in the matching section. • Sequence OK in eachsectorwhen applicable • Note : RU circuit not poweredbecause not commissionnedyet. S. Le Naour / MP3 meeting

  14. Tests PGC 2 • Heatrun of the completesector. Pictures of TT891a variation available on my public/MP3/PGC/PGC2 • Sector 1-2 : 4 valves regulation to improve : DACB34/42, DXCX02, DXBX01 • Sector 2-3 all regulation OK now • Sector 3-4 : 6 valves regulation to improve : DAGB06/10/13, DAGC02,07,08 – Cryostartsometimeslostbecause of DAGB10 • Sector 4-5 all regulation OK • Sector 5-6 : 1 valve regulation to improve : DAKC09 • Sector 6-7 : Not done, but a plateau of 1½h for PGC1.5 • Sector 7-8 : 3 valves regulation to improve : DAOC11, DMAC01, DXGX03 S. Le Naour / MP3 meeting

  15. Tests PGC 2 • Heatrun of the completesector. • Sector 8-1 : 12 valves regulation to improveDAAB03/06, DAAC01/09, DAPB14/43, DAPC10, DLAC11, DXAX01/03/04, DXHX06 • Heatrun on triplet • Heatrun on triplet made withreducedcurrent 3900A and 1900A • Heatrunwith 5900A in RQX.R2 : variation of 17K on TT893 with CL2, only 8K with CL1 : similarduringPNO.d11 • Heatrunwith 5900A in RQX.R5 not done S. Le Naour / MP3 meeting

  16. Tests PGC 2 • Heatrun on triplets. • Only circuits with HTS leads have been checked, but itwillbeworthchecking on triplet correctors (herebelow RCBXV3.L1) S. Le Naour / MP3 meeting
