To achieve high sensitivity, large collecting area is needed and dispersion due to the interstellar medium should be removed. To survey a large part of the sky in reasonable time, a telescope that forms multiple simultaneous beams is desirable. We have developed a novel FPGA-based transient search engine that is suitable for these circumstances. It accepts short-integration-time spectral power measurements from each beam of the ","authors_text":"Joseph Trinh, Larry D'Addario, Nathan Clarke, Robert Navarro","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2014-03-11T03:06:53Z","title":"A Multi-Beam Radio Transient Detector With Real-Time De-Dispersion Over a Wide DM Range"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1403.2468","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:b333beb9fce7b366962b520a0f3cd0474c725322d352c75747804c03cc9c6826","target":"record","created_at":"2026-05-18T02:56:43Z","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":"6ed3a019ee1c8d82a77186172e32b87d874d21b1b6c975cb7e4e52ec839b0a05","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2014-03-11T03:06:53Z","title_canon_sha256":"46ef7aa22c96b6c3958f31fb994f3fe581e09ab314149f5ddf8b0e41a235d8e9"},"schema_version":"1.0","source":{"id":"1403.2468","kind":"arxiv","version":1}},"canonical_sha256":"f621cdfde0f3ab49a19aed674d2a35ec2ff077def830955a5073ec9741ac2190","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f621cdfde0f3ab49a19aed674d2a35ec2ff077def830955a5073ec9741ac2190","first_computed_at":"2026-05-18T02:56:43.248611Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:56:43.248611Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"pQ8XwpwjHD3lZb4UuNJFICrr2gxhhiFpmHaKDfSO3VDEaLp54C3BfqMZp/WGZvZHj+c7nto04WrMci5XB5aZDg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:56:43.249147Z","signed_message":"canonical_sha256_bytes"},"source_id":"1403.2468","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b333beb9fce7b366962b520a0f3cd0474c725322d352c75747804c03cc9c6826","sha256:7cd5561709fa220e142ce423e4639557657a6251db06d9268e8ee5d6b8a65bcb"],"state_sha256":"bc7c59064f6b2b5a22b9056ea807d20194ad72bf27abcae6c6ea1163d30c3652"}
