In this paper, we employ measurements from two DMTPC detectors, with operating pressures of 30-60 torr, to develop and validate a model of the directional response and performance of such detectors as a function of recoil energy. Using our model as a benchmark, we formulate the necessary specifications for a scalable directional detector with sensitivity comparable to th","authors_text":"Cosmin Deaconu, Gabriela Druitt, Jeremy Lopez, Jocelyn Monroe, Michael Leyton, Natalia Guerrero, Peter Fisher, Richard Eggleston, Ross Corliss, Shawn Henderson","cross_cats":["hep-ex","physics.ins-det"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2017-05-17T01:17:14Z","title":"Measurement of the directional sensitivity of DMTPC detectors"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1705.05965","kind":"arxiv","version":2},"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":"sha256:1ee424879be68006f26da2c60066cba8a2be86834d67e375b4d746260330a50a","target":"record","created_at":"2026-05-18T00:41:58Z","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":"c785c9d49a4df2a190547fc997d116634a177ba1927d14d4852133d586616312","cross_cats_sorted":["hep-ex","physics.ins-det"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2017-05-17T01:17:14Z","title_canon_sha256":"dca76ce4a972fc6305f3d30fb936d67eaea4c508b9792c23b8904f4e4fe99611"},"schema_version":"1.0","source":{"id":"1705.05965","kind":"arxiv","version":2}},"canonical_sha256":"48168e95b4ba00d5613b782b29d6038e3affe66ceb59d9612551be2f629aa5ac","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"48168e95b4ba00d5613b782b29d6038e3affe66ceb59d9612551be2f629aa5ac","first_computed_at":"2026-05-18T00:41:58.905727Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:41:58.905727Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"jOB3rTsYkNjmPjdm0b8EnL2BPUrCWeiVj1K6GvXIqlr0Rj5pMYkJgEfXub+f4EjZlkw+pAC7PiAHgKZd6KmsDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:41:58.906419Z","signed_message":"canonical_sha256_bytes"},"source_id":"1705.05965","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1ee424879be68006f26da2c60066cba8a2be86834d67e375b4d746260330a50a","sha256:9a7f665ab4cff3fffa99a20c9124153be086ec26b77c619b6729bbc8843cb268"],"state_sha256":"44e0c69fdafa2a17b9a15822c0a283058374ce21e4d966d616410a71ba28f22d"}
