  1. MP3 Meeting : SLN, 12/02/2013 HWC 2013 : Powering to 7TevSpecial cases

  2. IPD / IPQ and IT • IPQ : RAS – Nothing to declare • IPD : • RD2.R8(quenched 4 times at less than 6.8 TeV) • RD3.R4 and RD4.R4 (commissioned to 6.6 and 6.3 TeV) • IT : • RQX.L5& RQX.R5 (commissioned to less than 5 TeV due to the change of nominal current)

  3. 600A • RCO.A78B2 • Le circuit RCO.A78B2 n’est pas ouvert. • Notre idée est de faire du diagnostic ds le tunnel durant les phases powering. Installation d’un système de mesure en // de QPS, puis éventuellement, localiser la faute le long de l’ARC. • RQTF.A45B2 • 3 quenchesat 550A on flat top • RQS.A34B2 & RQS.L2 • Whyonly 400A? Probablycurrent value given by Gianluigi/Massimo

  4. 600A - RQTL • Thosewhich are looking OK. • 3 (double aperture) were not poweredabove 300A or 400A

  5. 600A - RQTL • Thosewhich are more tricky In blue : weakmagnetsaccording to M & M’s In red: Additionnalweakmagnets or magnetswhichquenchedbelow the request value.

  6. 600A-RQTL • 3 RQTL are not weakmagnetsaccording to Mikko but theywere not powered up to 300A or 400A. • 2 RQTL are weakmagnets, but not considered as such by M & M’s. Neverthelesstheywere not poweredmore than400A up to now. MEB in 2006 suggested 431A and the extrapolation from 2012 opticsis 340A maximum • 1 RQTL (not weak) shows a training above 500A
