It is designed to address the science theme \"The Hot and Energetic Universe\", performing X-ray observations (0.2-12 keV) at the L2 Sun-Earth Lagrangian point. The X-IFU is one of the two instruments of the payload. It is a cryogenic spectrometer providing spatially resolved high-resolution spectroscopy. The core of the instrument is a large array of TES microcalorimeters, operated at a 50 mK thermal bath. The X-IFU performances would be strongly degraded by the particle background expected in the L2 environment, thus advanced red"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1904.03307","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
