Detector¶
The coherent-scattering area detectors, the WAXS detector, the beam stop, and the beam-position monitors. First cut; PVs read from the beamline config, carried confirm.
9-ID detection is coherent area detectors for the small-angle pattern (a Pilatus and an Eiger on a translation stage), a wide-angle detector on a pedestal for GIWAXS, the beam stop that blocks the direct beam, and the beam-position monitors that diagnose and normalize the beam. They are modelled in the detection stage of the descriptor.
The detectors reuse the Camera Family, the stage LinearStage, and the beam stop the catalog BeamStop Family. The TetrAMM and the two XBPMs bind a loose BeamPositionMonitor Family that 4-ID and 8-ID also use, held for gate-review.

Families¶
Reused from the catalog: Camera (the Pilatus, Eiger, and WAXS detectors), LinearStage (the detector stage), and BeamStop. The beam-position monitors bind a loose BeamPositionMonitor Family, held for gate-review even though 9-ID is a further independent beamline to use it: the Sensor fold-vs-promote question is open (DIAG-1 / FLUX-1; see Model). Whether each monitor is a true position monitor or an intensity (I0) normalizer is BPM-1; the detector models are DET-1. See Inventory for the Asset tree.
