Collimation Engineering Change Requests (ECRs) for LS2: HL-LHC and Consolidation
We collect here the ECR document for the upgrades in LS2, within HL-LHC and Consolidation projects.
This follow the present version of the upgrade master plan: version 21/03/2018; UPDATE: new master plan with granularity of individual collimator installation: 25/06/2018 !
Remarks/comments:
- Draft documents are loaded on this site: for reference, refer to EDMS links (official approval loops)!
- Legend:
V1: First versions sent to the ECR team (April 4th, 2018 !);
V2: Updated version after ECR team's comment (using latest templates). May 25th, 2018.
V3: (for EDMS submissions): Implemented feedback from vacuum team.
V4: Updated versions including the comments from the first approval loop in EDMS.
V3b: (for EDMS submissions): EDMS version for the TCAPM only, after iterations with paragraphs from vacuum team.

Remarks/comments:
- Crystal collimation is for the moment not in the upgrade baseline.
The installation carried out in LS1 for MD studies is not part of these
conceptual specifications.
- Other collimator activities to be addressed as system
consolidation are not discussed in these documents. Only the upgrades
involving new designs is addressed.
- Collimator that might have to be changes in order to withstand the
failure scenarios with updated HL/LIU beam parameters are also not
discussed for here (e.g., new primary and secondary collimators to be
changed in case the 288 bunch loss scenario at injection is no more
safe).
