Production of muons from pion decay is studied. Lithium lenses and solenoids are considered for focussing pions from a target, and for matching the pions into a decay channel. Pion decay channels of alternating quadrupoles and long solenoids are compared. Monte Carlo simulations are presented for production of $\\pi \\rightarrow \\mu $ by protons over a wide energy range, and criteria for choosing the best proton energy are discussed.","authors_text":"D.Neuffer (CEBAF), D.Winn (Fairfield Univ.), J.C.Gallardo, R.B.Palmer, R.C.Fernow, Y.Torun (BNL)","cross_cats":["physics.acc-ph"],"headline":"","license":"","primary_cat":"acc-phys","submitted_at":"1995-03-31T01:43:48Z","title":"MONTE CARLO SIMULATIONS OF MUON PRODUCTION"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"acc-phys/9503004","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":"sha256:1ccee8a01d31653ab2b569e239083916d0f6695e4784db182376aa8f0eda952e","target":"record","created_at":"2026-05-18T02:40:47Z","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":"c82c4335f35c065942b000e8cc1ab935958691b764ba59c2bc7164bb8bb80834","cross_cats_sorted":["physics.acc-ph"],"license":"","primary_cat":"acc-phys","submitted_at":"1995-03-31T01:43:48Z","title_canon_sha256":"b63d1ac2bd7fb021b037386ff04c38b9a603ec51f3687b7e1a5429afa1aeb7df"},"schema_version":"1.0","source":{"id":"acc-phys/9503004","kind":"arxiv","version":1}},"canonical_sha256":"f882287c1feb8596f0c4d271e4734d56dade73e5b6a15c5e6e57ea966f65bcaa","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f882287c1feb8596f0c4d271e4734d56dade73e5b6a15c5e6e57ea966f65bcaa","first_computed_at":"2026-05-18T02:40:47.915489Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:40:47.915489Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hU2KJUbSKU3zf0FsdN2wlNV+kr06kyT10K3LzfbzmUVwCOUpPjZEI90IomMLq5HiR224Qwu4GExaQ/bM6LzdBw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:40:47.915989Z","signed_message":"canonical_sha256_bytes"},"source_id":"acc-phys/9503004","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1ccee8a01d31653ab2b569e239083916d0f6695e4784db182376aa8f0eda952e","sha256:62ee4e6c08d523e5cda705e8f921893ac3247fb36782619d6d0a4979abea91c2"],"state_sha256":"22c061e65915c016b5ef79742d2ee06dda2c6771e5bec101a1496bc5853ef88e"}
