MPP Workshop 2019

7 May 2019, 08:00 → 8 May 2019, 18:00 Europe/Zurich

Hexagonal (Chateau de Bossey)

Christoph Wiesner (CERN), Daniel Wollmann (CERN), Jan Uythoven (CERN), Jorg Wenninger (CERN), Markus Zerlauth (CERN)

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

Session Chairs:

B. Salvachua & M. Gasior

15:40 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)?

16:10 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?
