15. B.P. BIS Commissioning in point 8: follow-up 15 of 16 summing up ●Fruitful collaboration BIS  User Systems ●Most of the links (LHC-ring BIS) have been validated – LHCb Detector & Velo: both OK – LHCb Magnet signal out of limits => test postponed ●Links for Injection Inhibit partially done: – CIBU for Beam-2 Inhibit: input signals OK – CIBF for Beam-1 Inhibit: input signals OK – Tests are going to continued when cable and F.O. will be in place.
