The control system for the KEK electron/positron injector-linac has been using Unix workstations and VME computers since 1993. During the eight-year operation, we extended the system by introducing a) Windows PCs, b) PLC controllers with a network interface, and c) web servers based on modern information technology. Although such new subsystems are essential to improve control functionalities, they often cause communication problems with the or","authors_text":"K.Furukawa, N.Kamikubota, S.Kusano, T.Obata","cross_cats":[],"headline":"","license":"","primary_cat":"physics.acc-ph","submitted_at":"2001-12-13T11:02:15Z","title":"Introduction of Modern Subsystems at the KEK Injector-linac"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"physics/0112037","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:ec3b3bfcfe22b9578b476fe9e35eb699e3c0c801017a1ef300a21528d200a87a","target":"record","created_at":"2026-05-18T00:06:16Z","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":"0f60f0e7ac18ff5331160ced5705733fb6ee15d28a82ea82a99b29570958a6fd","cross_cats_sorted":[],"license":"","primary_cat":"physics.acc-ph","submitted_at":"2001-12-13T11:02:15Z","title_canon_sha256":"6ee3f12626a1c90153d3f0ab929bef6a9ecf59a86a981376b1f3bafdd65d313c"},"schema_version":"1.0","source":{"id":"physics/0112037","kind":"arxiv","version":1}},"canonical_sha256":"9499a62e67d815d9dcba6a91821d65494ea59cca27d2c383d7da0b03db4eb4c9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9499a62e67d815d9dcba6a91821d65494ea59cca27d2c383d7da0b03db4eb4c9","first_computed_at":"2026-05-18T00:06:16.587543Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:06:16.587543Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"DCdQIh/476vXy8rQoo/ISKM+fHVzr7ah83txAzhKESyJHEzhKip0gXSasGp5bJGlS/EwED+BNl4WwyIxlIS3AA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:06:16.588212Z","signed_message":"canonical_sha256_bytes"},"source_id":"physics/0112037","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ec3b3bfcfe22b9578b476fe9e35eb699e3c0c801017a1ef300a21528d200a87a","sha256:900d444b9beebabe08f25668ea372c8fc0a189ec9fe0448864c234b330dd06b9"],"state_sha256":"a10ec31d5df4bda0d0469e9e07189bc9e6409beeebc49f3b5a18af30f82ee737"}
