The magnetic field model consists of an unperturbed reversed-shear helical part and a perturbation consisting of a superposition of modes. Contrary to most of the previous studies, the particle trajectories are computed by directly solving the full Lorentz force equations of motion in a six-dimensional phase space using a sixth-order, implicit, symplectic Gauss-Legendre method. The level of stochasticity in the particle orbits is diagnosed using averaged, effective Poincare sec","authors_text":"Benjamin Cambon, Diego del Castillo-Negrete, Guilhem Dif-Pradalier, Michel Vittot, Shun Ogawa, Xavier Garbet, Xavier Leoncini","cross_cats":["physics.plasm-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nlin.CD","submitted_at":"2016-04-18T12:14:04Z","title":"Full particle orbit effects in regular and stochastic magnetic fields"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1604.05112","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:db79fb72e55af3729aa23a7d66ee703978e3e1807aa256ea62e0e3a15b6b8347","target":"record","created_at":"2026-05-18T01:03:44Z","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":"772a71d6875082a5aee12eb2aa31b2f1f28819649e65d5209946e108f6ae3e1e","cross_cats_sorted":["physics.plasm-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nlin.CD","submitted_at":"2016-04-18T12:14:04Z","title_canon_sha256":"fe0554f74c5567e0a3ff7f13cde83f15edefa05e1de2f74a51afb76de996bd97"},"schema_version":"1.0","source":{"id":"1604.05112","kind":"arxiv","version":2}},"canonical_sha256":"b68ff1d6bff8cb7a6946d31d57a82f486f95cd6be0de5977854a2f78ae178116","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b68ff1d6bff8cb7a6946d31d57a82f486f95cd6be0de5977854a2f78ae178116","first_computed_at":"2026-05-18T01:03:44.027766Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:03:44.027766Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"wKaKPXR/9QRehtMyv0ahlGo2NQcCVHpC2oP7P04LECLbzLcU1cXBPFmmVbDKx6P1/eaBCDpuR9FAJAGVMvfrAw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:03:44.028340Z","signed_message":"canonical_sha256_bytes"},"source_id":"1604.05112","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:db79fb72e55af3729aa23a7d66ee703978e3e1807aa256ea62e0e3a15b6b8347","sha256:9677a699871c1846a48dca07b86db988fec51434b65b897e526e8e8644fb5f7f"],"state_sha256":"d86a6f9c31c0558a25e2ade918f57d9c32a68d8261b1025ebef8c3e5673b4db8"}
