We can use LWFA to produce the femtosecond electron beam. The peak current of the produced beam can reach tens of $kA$ and is high enough to drive XFEL so that the present bunch compressing technique can be deserted. The output optical pusle length can be as short as $ 1 fs $.","authors_text":"Xiongwei Zhu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.acc-ph","submitted_at":"2011-01-05T06:33:58Z","title":"LWFA as a Preinjector for XFEL Driver Linac"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1101.0889","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:fcfd224c68714f63735936e5e539cd1e44f55e5eec3966544ff09c709844d168","target":"record","created_at":"2026-05-18T04:25:37Z","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":"17c3fe6f1caf5dc6ab8c5296483c3f0c7373acf29040c2bb7c5af302eab1129d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.acc-ph","submitted_at":"2011-01-05T06:33:58Z","title_canon_sha256":"0dbf12769488e4a863ab94fce9a813ad5964baf1b42d43aa179e8c5387e3e13d"},"schema_version":"1.0","source":{"id":"1101.0889","kind":"arxiv","version":2}},"canonical_sha256":"41b05330771e54d56f94c982de52ba27b1e84bbcf9c44a99ae4a4e205db7a81b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"41b05330771e54d56f94c982de52ba27b1e84bbcf9c44a99ae4a4e205db7a81b","first_computed_at":"2026-05-18T04:25:37.635941Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:25:37.635941Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"TpEh1r4xE2NNKKB/C5hOrOzsy0QIkgULK9j/Nk63MS0qx06XoOIdCOgRfyyGSKD8dA8+ke7X9nhyccGEVwrPDw==","signature_status":"signed_v1","signed_at":"2026-05-18T04:25:37.636412Z","signed_message":"canonical_sha256_bytes"},"source_id":"1101.0889","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:fcfd224c68714f63735936e5e539cd1e44f55e5eec3966544ff09c709844d168","sha256:137ea4c6816f2e9c9a4bd4ef36bee417c0797fe577f81dbe4b94fd42363e11d3"],"state_sha256":"4822c2f24e441e27cbea0b392beadb91066e630a1623412d5c94918bc006ed9e"}
