Starting with an initial estimate for the orbital magnetic moment, the higher-order drift process of ExB is configured to balance the gradient-B drift motion of the electron in such a way as to guide the trajectory into the standing voltage potential along the mid-plane of the filter. As a function of drift distance along the length of the filter, the filter zooms in with exponentially increasing precision on the transverse velocity component of the e","authors_text":"A.Bosca, A.Ferella, A.G.Cocco, A.Giachero, A.Molinero-Vela, A.Nucciotti, A.P.Colijn, A.Polosa, A.Puiu, C.Chang, C.F.Strid, C.Gentile, C.G.Tully, C.Mancini-Terracciano, C.Mariani, C.Perez de los Heros, E.Ferri, E.Monticone, F.Calle, F.Gatti, F.Pandolfi, F.Zhao, G.Cavoto, G.Garcia Gomez-Tejedor, G.Mangano, J.Carabe-Lopez, J.Conrad, J.Gudmundsson, J.Martinez, J.Pedros, K.M.Zurek, K.Schaeffner, L.E.Marcucci, M.Biasotti, M.Faverzani, M.G.Betti, M.Lisanti, M.Messina, M.Rajteri, N.D'Ambrosio, N.Rossi, O.Pisanti, P.F.de Salas, P.Garcia-Abia, R.Santorelli, S.Gariazzo, S.Pastor, W.Chung, Y.Hochberg, Y.Kahn, Y.Raitses","cross_cats":["physics.ins-det"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2018-10-15T21:23:07Z","title":"A Design for an Electromagnetic Filter for Precision Energy Measurements at the Tritium Endpoint"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1810.06703","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:bf800e2e006d97e4dfa7768b945c76d8e0a559c60d7e581b74b7e6f028e15a38","target":"record","created_at":"2026-05-17T23:47:29Z","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":"7b6efb52ac1e3bbfc2444754830ad6c1343b7c0006bd69616061170c2041564e","cross_cats_sorted":["physics.ins-det"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2018-10-15T21:23:07Z","title_canon_sha256":"f0031e9ed30712bd6efcab0745fad7bf0d0e993d5c25d76f9d36109feca5a34c"},"schema_version":"1.0","source":{"id":"1810.06703","kind":"arxiv","version":1}},"canonical_sha256":"e4471a2c3cae46d3494ade52e75cdfff1a7c7d0b35d2408338b01da7e6b771f8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e4471a2c3cae46d3494ade52e75cdfff1a7c7d0b35d2408338b01da7e6b771f8","first_computed_at":"2026-05-17T23:47:29.987745Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:47:29.987745Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"TD2ZA1zwYcLrzRKa5K8CoiaOGJnm91OmwJ6Yrp7NvtUCKcFmGlMfimTKeBD6x4E/yQ3DOdE43pZJfUyuWfrPAQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:47:29.988348Z","signed_message":"canonical_sha256_bytes"},"source_id":"1810.06703","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:bf800e2e006d97e4dfa7768b945c76d8e0a559c60d7e581b74b7e6f028e15a38","sha256:7544e64ad6e902026489f20e5d3cd51e4bb6c3c7b7ba2d852c7d2ca2f55dac85"],"state_sha256":"d67b096a0a16832e980dc8dc2961c3a2201dd6ce20defa8ab99a1c00dfcc401f"}
