Upgrades of the detectors and trigger components are needed to cope with increasingly challenging conditions of the HL-LHC. New irradiation tests are performed to ensure that the muon detectors will survive the harsher conditions and operate reliably. The new CERN GIF++ (Gamma Irradiation Facility) allowed to perform aging tests. We present results in terms of system performance under large backgrounds and after accelerated aging tests. New detectors will be added to improve the performance in the critical forward region: gas electron multiplie","authors_text":"Jian Wang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.ins-det","submitted_at":"2018-09-05T22:55:40Z","title":"Upgrade plans and ageing studies for the CMS muon system in preparation of HL-LHC"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1809.01760","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:4e5383feafe93f4cfee233c63c1466527cb98602c452dab85bbecde2fdd24cc4","target":"record","created_at":"2026-05-18T00:06:21Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"94be4054a0b5c353a97b5d12d56f1a937beea70c9f7630fd1cb0620c2027aefb","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.ins-det","submitted_at":"2018-09-05T22:55:40Z","title_canon_sha256":"b2f7b09a789616d2ca4d487d6b20ffe9f1466211305d94bd42912041ae2a2794"},"schema_version":"1.0","source":{"id":"1809.01760","kind":"arxiv","version":1}},"canonical_sha256":"f1c3767f92e7bcd7302d9f26b6f8b75e27083aef8cc76aa986791a61aba2e0d9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f1c3767f92e7bcd7302d9f26b6f8b75e27083aef8cc76aa986791a61aba2e0d9","first_computed_at":"2026-05-18T00:06:21.997455Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:06:21.997455Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+kOSLcLoLjQqGc4AGC08kBpmLS7jlcWGU/EVbQ6ov7rbtHbqio5YbfIw5Y9tYP67y1pmnJVXHR7R9hq7zz1vDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:06:21.998021Z","signed_message":"canonical_sha256_bytes"},"source_id":"1809.01760","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4e5383feafe93f4cfee233c63c1466527cb98602c452dab85bbecde2fdd24cc4","sha256:2076061aad5a947916a94a4d73458142148603965c98b648225e86e033a1d827"],"state_sha256":"08856db7e23a554c114207f802a0f7dd87457708bc96191f4f48061360df6d72"}
