The detector was mounted in the focal plane of the Abrixas X-Ray telescope at the CAST experiment at CERN. The detector is sensitive to soft X-Rays in a broad energy range (0.3--10 keV) and thus enables the search for solar chameleons. Smooth detector operation during CAST data taking in autumn 2014 has been achieved. Preliminary analysis of background data indicates a background rate of $1-5\\times 10^{-5}\\,\\mathrm{keV}^{-1}\\mat","authors_text":"Christoph Krieger, Jochen Kaminski, Klaus Desch, Michael Lupberger","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.ins-det","submitted_at":"2015-09-04T11:55:43Z","title":"Using an InGrid Detector to Search for Solar Chameleons with CAST"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1509.01418","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:e95ceb1ec4087c0b390888f7d8d9b1e2e9ed24ec064b4a6d2c5506f73e83af0a","target":"record","created_at":"2026-05-18T01:33:57Z","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":"ba0e6481aaa3034501f7c53b5c1ae3377502f683b9c6907fdddfb452509ead83","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.ins-det","submitted_at":"2015-09-04T11:55:43Z","title_canon_sha256":"f467ed904a6a084c672a0ef0d77c4e2636546ac47e52c4afda88f2796e87ed5e"},"schema_version":"1.0","source":{"id":"1509.01418","kind":"arxiv","version":1}},"canonical_sha256":"9f74ee610b92f40ceeedd121cfb521e2991b1257d4edb4a5a9b7740d871b9e10","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9f74ee610b92f40ceeedd121cfb521e2991b1257d4edb4a5a9b7740d871b9e10","first_computed_at":"2026-05-18T01:33:57.723011Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:33:57.723011Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1VGnQiEqOIrGZBl6cjYRTkW17s7J/3RJnDp+8FmylIYuVw4NjeszGFqQpUhXge7Ce/Jif6qpViJJHfssOJOcBw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:33:57.723579Z","signed_message":"canonical_sha256_bytes"},"source_id":"1509.01418","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e95ceb1ec4087c0b390888f7d8d9b1e2e9ed24ec064b4a6d2c5506f73e83af0a","sha256:60a450198c88c1ac6af1f8ac7cb7b738707e0621b219e2b2557799198f2aefcb"],"state_sha256":"b702e5f2f26070d2b134d27b831e5e0bdd767c9c7a8c0b446f2fb8b6636b648d"}
