Detector¶
The DECTRIS EIGER2 X 16M area detector and its translation stage, the on-axis viewing camera, and the beam-position diagnostics. The EIGER2 streams over ZMQ (migrating to DESY ASAP::O) into the mesh-scan / Dozor analysis path; control is through the DCSS workflow.
Enclosure: TPS-07A-EH.
Note
The EIGER2 X 16M reads the rotation frames at up to 130 Hz. Its acquisition is commanded through the DCSS / DHS workflow (the EPICS floor), and frames egress over a ZMQ stream, with a late-2025 ASAP::O frame-ingestion path feeding Dozor spot scoring and CHiMP crystal detection for mesh scans. CORA treats the frame egress as a TransferPort leg and the Dozor / CHiMP scoring as ComputePort work, OFF the control seam (it is Observe / Compute, not Actuate). The detector minimum-distance interlock (139 mm) is a hard safety limit read from the control tree.

EigerDetector |
Camera |
DECTRIS EIGER2 X 16M area detector (~130 Hz) reading the rotation-MX frames. Frames stream over ZMQ (writers for HDF5/NeXus, CBF, TIFF; migrating to DESY ASAP::O). Reuses Camera. Driven through the DCSS / DHS workflow over the EPICS floor; SIMPLON endpoint / detector PVs pending (DET-1). | confirm |
