Non-stationary phenomena common to the entire range of $E \\times B$ devices, such as oscillations and instabilities, are likely to exist in the magnetic nozzle, according to the mounting experimental evidence. These mechanisms could lead to anomalous cross-field transport, either enhancing the plasma plume divergence or favoring electron detachment. In this work we present a local linear analysis of fluid instabilities relevant for said devices, expanding on previous works with the ","authors_text":"Eduardo Ahedo, Mario Merino, Matteo Ripoli","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.plasm-ph","submitted_at":"2024-12-13T11:58:32Z","title":"Lower-Hybrid Drift Instabilities in a magnetic nozzle"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2412.10070","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:f0a89cc259c7eb2e8075efd295cb5fa3cd9b82e36e29cae534cd57f3d456ab89","target":"record","created_at":"2026-07-05T09:48:46Z","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":"9102e26cb20985b9343fa98e91959eaf50d47a5f4f1223d331255ecaaa21b097","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.plasm-ph","submitted_at":"2024-12-13T11:58:32Z","title_canon_sha256":"18c2cb02cba1bd7c418f39cde1cf4d90f0f5f21a8c3f34298820d613c59ed7e1"},"schema_version":"1.0","source":{"id":"2412.10070","kind":"arxiv","version":1}},"canonical_sha256":"e33b770ab82bdbd7c636c2eac40fb205c24c0da5e4def1e989987ce946bdfe6b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e33b770ab82bdbd7c636c2eac40fb205c24c0da5e4def1e989987ce946bdfe6b","first_computed_at":"2026-07-05T09:48:46.544112Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:48:46.544112Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"NHCI0Q4zhIenu5GPqxPYMNjd4WqV+xVNBBXhbNranJHlmU/Dn80u3UfHNQMr2zzE8lE0IWEzqiWnrmP9y0T9Bw==","signature_status":"signed_v1","signed_at":"2026-07-05T09:48:46.544584Z","signed_message":"canonical_sha256_bytes"},"source_id":"2412.10070","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f0a89cc259c7eb2e8075efd295cb5fa3cd9b82e36e29cae534cd57f3d456ab89","sha256:672c175f56927a4c0eff325e376b749a054d7886fe5bf5653f02775804dd5f1a"],"state_sha256":"c2ef1793997887fe12e4e60f0f1c1344ccfa0a1f5b6be752adbc3259e9274a64"}
