Conclusion • The vacuum group does not see any reason to trigger a beam dump from a vacuum signal • If the decision from the management is to use a hardware alarm from vacuum, the vacuum group can provide a digital signal (relay) to the equipment owner • The vacuum group will not be responsible of the CIBU and this crate shall be installed in the racks of the equipment owner • The cables shall be requested by the equipment owner • If an HW alarm is used, the relays thresholds must be defined by the equipment owner • Vacuum/pressure measurements can be published in CMW/DIP/LASER • Vacuum/pressure measurements are published in XPOC for post mortem analysis • New gauge in TD 62 are already published • New gauge in TD 68 will be published during the next SCADA update (March) • Vacuum SCADA can send SMS on a specific threshold, slope, … 02/10/2020 G.

Changes during EYETS Beam dump lines: • TD 6 x: New piezo gauges with HW alarms Interlock for Vacuum sector valves: • A 6 L 1. R: new ion pump and configuration • C 4 L 2. C: new interlock cabling in UA 23 • LSS 7: new ion pumps cabling distribution • A 4 L 8. C: new interlock cabling in UA 83 • I 5 R 8. B: new Penning gauge Alarms to cryogenics: • SA, IT Pt 1: New piezo controllers for insulation vacuum 02/10/2020 G. Pigny TE/VSC/ICM 9

Commissioning after EYETS TDE 6 x HW alarms: • Procedure shall be added in the MPS commissioning document • Complete HW and SW alarms have to be tested up to the BIS/SIS Vacuum sector valves interlocks: • Complete HW interlock chain has to be tested up to the BIS Vacuum alarms provided to other systems: • Complete test up to the user systems has to be performed • MKI • MKB • RF • CRYO (insulation vacuum) All the procedures (except the new TDE interlocks) are described in the MPS aspects of the Vacuum System Commissioning LHC-OP-MPS-006 02/10/2020 G.
