Description
The principle aims of the workshop are to:
Review the status, foreseen and required changes in the machine protection systems during LS2 to prepare operation with LIU beams. The workshop will cover LHC and injector related topics:
- Learning from Run 2 (injectors and LHC)
- Foreseen changes to the machine protection and related systems
- Challenges in injectors and LHC with LIU beams and other new operational parameters (optics, beam energy, 11 T)
- Preparatory tests or MDs which need to be performed during Run 3 (in the injectors and the LHC), which are outside the operational envelope, to prepare for HL-LHC

Machine protection challenges in the SPS
- Machine protection in the SPS overview – LHC extractions, SPS ring
- LS2 upgrades:
- SBDS, injection interlocking
- Absorbers + SMP
- WIC: HIL loop
- BI interlocking plus additional requirements for SMP
- Status and requirements for slow extraction
Handling MDs and non-standard operation in the SPS
UA9, COLDEX, crab cavities
Speaker: Kevin Shing Bruce Li (CERN) -
25
Linac 4 - experience and open points
- Lessons learnt for MP hole in vacuum pipe, diamond BLMs broken, stripping foil broken, other beam incidents …
- Report on LINAC4 review
- BIS configuration – check with PSB talk, as one common BIS architecture. New specification
- Experience with settings management
- Outstanding issues
- Source interlock (RF HV).
- Use of timing to select beams. Interface to External Conditions and SIS

SIS, external conditions and timing system
New SPS GMT monitoring to be put in place in SPS after LS2
- External conditions – SIS – Timing
- What is in place for the different injectors
- Upgrade of EC foreseen for LS2, problems interfacing FGC
- Longer term plans for SIS and external conditions development. Should these two be merged in the long-term future (next to a hardware BIS)?Speaker: Grzegorz Kruk (CERN) -
27
PS and machine protection
- Experience with protection
- Protection strategy mid and long-term
- External conditions & SIS
- External conditions upgrade LS2 by BE-ICS check against talk Greg/Miguel below for overlap
- No safe beam flag in PSB and PS, manage interlocks per beam type / external conditions
- What about BIS in the long-term future? PS dump, connection to PSB extraction BIC
- PS SEM grids and ‘ralentisseur’
- Which role plays the wall between PS and booster?
Speaker: Klaus Hanke (CERN) -
28
Booster interlocking and operational scenarios
- Booster interlocking
- Upgrade of switching magnet power supply BHZxxx which leads to dump
- External conditions, SIS, BIS and 4-ring flexibility
- Procedures for masking BIS and making changes to timing to get beam for <4 rings. Automate? Software, reminders?
- Fault diagnostic – BIS diagnostics by cycle. BIS GUI OP and history buffers.
- Operability?
