1. LBDS: setting the scenes

Chiara Bracco (CERN)

05/02/2019, 08:45

a) Existing design: kickers, protection elements, controls logic, BETS, considered failures and failure rates etc.
b) Operation during past runs: reliability, new failures (impact on beam and protection elements) and mitigations applied up to now (generator cleaning, radiation shielding).
c) Possible limitations for Run III.
d) New requests (additional kickers or separate vacuum tanks) and...

3. LBDS kickers: HW upgrade

Laurent Sylvain Ducimetiere (CERN), Viliam Senaj (CERN)

05/02/2019, 09:15

a) Actions foreseen during LS2 and present status (switch consolidation, grounding)
b) additional MKBs or other solutions to be investigated (separate vacuum tank) with technical details.
When possible applying first mitigations? Latest date to start production.

5. LBDS kickers: controls upgrade

Etienne Carlier (CERN), Nicolas Magnin (CERN)

05/02/2019, 09:40

a) Upgrade foreseen during LS2 (MKB re-triggering, IPOC upgrade, sparking surveillance, etc.)
b) Actions foreseen for LS3 (what is in the baseline: Triggering synchronization distribution, powering etc.)
c) What is not in the baseline and might be needed (replacement of aging equipment, etc. consolidation? Operational budget?)

7. Return of experience from Run II operation and Implications for Run III and HL-LHC

Antonio Perillo Marcone (CERN)

05/02/2019, 10:30

a) Review of existing design, design choices, etc.
b) Operation during run II: vibrations, leaks.
C) actions foreseen during LS2 and actions from the past (N2 bottle on surface, design and construction of new back windows, decision on gaskets, etc..) .

9. Energy deposition and accident scenarios, RunII, RunIII and HL-LHC¶

Anton Lechner (CERN)

05/02/2019, 11:05

a) worst accidental design scenario known until and post RunII, worst design accidental scenario for the future.
b) Run III operational scenarios.

11. Thermal and structural simulations of Core and windows

Tobias Polzin (CERN)

05/02/2019, 11:35

How we study the problem, why the windows are an issue, why the core might be an issue, what are the missing information in terms of properties, what is the dominating problem, severity of different failure scenarios on the core, etc…

15. Status of material properties and testing at CERN

Michael Guinchard (CERN)

05/02/2019, 13:50

Material properties needed to assess the core performances, tests done @ CERN, tests to be done outside.

Marco Calviani (CERN)

05/02/2019, 14:15

a) current collaboration and activities for further decision (core, windows)
b) plan for the future and possible options.
c) decision points and how we decide.
d) problems to be solved and how we would proceed (new gaskets, new core, damping system, eventual staged upgrade during run III).
