Power Interlock Controller (PIC) No electrical lock-out required Description YETS LS2 Comment Protection of 11 T trim circuit, new PIC functionality X Needed before powering. Spec in preparation. General maintenance and follow-up if needed, all systems Check of INFOR EAM database relative to operational devices Access needed WINCC OA maintenance (BE-ICS) PLC Step7 conversion to TIA Portal Project (BE-ICS) Re-engineering of PLC algorithm (TE-MPE & BE ICS) LHC Coordination Meeting, 26/09/2017 MPE-MI, Jan Uythoven

Fast Magnet Current Change Monitor (FMCM) No electrical lock-out needed Description YETS LS2 Comment General maintenance and follow-up if needed, all systems X Check of INFOR EAM database relative to operational devices Exchange of LHC-FMCM in points 3&7 with new series Operational tests needed Exchange of LHC-FMCM in points 1, 2,5 and 6 with new series LHC Coordination Meeting, 26/09/2017 MPE-MI, Jan Uythoven

Beam Interlock System (BIS) No electrical lock-out Description YETS LS2 Comment CIBDS local loop connector replacement (new CIBDS) X Point 6 SFP optical power calibration All IPs Add TSU in the SFP loop New TDE connections in IP6 Re-commissioning all non-conform CIBUs Two new MKB connections in point 6 Increse number of user connections BICs UA63 and UA67 Deploy and test BIS 1.23 if required Install BIS v2 for testing None of the above requires many days per intervention LHC Coordination Meeting, 26/09/2017 MPE-MI, Jan Uythoven

Warm Magnet Interlock Controller (WIC) Description YETS LS2 Comment BBCW wire collimator IP1, interlocking X IP3 and IP7, WIC update following removal of magnets and interlock LHC Coordination Meeting, 26/09/2017 MPE-MI, Jan Uythoven

MPE – MP Software, main points YETS 2017/2018: Maintenance work on the LHC Post Mortem System to address recent performance issues. The most likely solution will be to unload the server by migrating historic data to a different physical machine (while maintaining it accessible for the analysis tools). This has to be done ahead of the start of HWC, i.e. before the end of January. Validation will be done by doing dry Post Mortem dumps. LS2: New version of PM system replacing the current infrastructure. Possibly this will be joined with the NXCLAS (new Logging system).  The system has to be ready by mid-end 2019 to allow people to efficiently migrate to the new infrastructure and avoid any delay in the start of IST and commissioning activities.  New version of software layer for LHC quench detection. The system has to be ready by mid-end 2019 to allow Reiner and Co to do an early validation of the DYPQ upgrades and prepare the IST tests. Massive migration of FESA classes for BIS, SMP, FMCM,.. to comply with the eradication of FESA 2 announced by CO. Again to be ready for all IST and commissioning tests of the respective equipment.
