BLMTWG Engineering Change Requests (ECRs)

BLM threshold changes are documented in Engineering Change Requests (LHC-BLM-ECR-xxx). Other technical information concerning BLM thresholds, e.g. model algorithms, are documented in Engineering Specifications (LHC-BLM-ES-xxx) . All documents are stored in EDMS (link). Links to individual documents can be found below (authentication needed to access EDMS pages):
