Detector

The energy-dispersive fluorescence detector in the 2-ID-D hutch. Design-phase; values carried as confirm.

The detector modelled here is what makes 2-ID-D a different shape from the tomography pilots: not a full-field imaging camera, but an energy-dispersive detector that records an X-ray fluorescence spectrum at each scan point. Element maps are fit from the per-point spectra downstream (EAA's XRF-Maps lineage: raw scan to fitted maps). It is modelled in the detection stage of the descriptor.

The model in one picture

The detection chain (containment, Asset.parent_id):

2-ID  (Unit, Asset)
└── FluorescenceDetector  (Device, Family EnergyDispersiveSpectrometer; spectrum per scan point)
        preamplifier + EPICS scalers + I0 flux monitors  (readout chain, DET-2, not separately modelled)

Unlike 2-BM and TomoWise, there is no scintillator, objective, or camera chain: the detector is a direct energy-dispersive device, and the per-point spectrum is the signal. It binds the EnergyDispersiveSpectrometer catalog Family, graduated once 2-ID and 7-BM shared it; that Family is the first to fill the Sensor Role with a science detector.

FluorescenceDetector	EnergyDispersiveSpectrometer	energy-dispersive fluorescence detector; model, element channels, and segmentation unconfirmed (DET-1)

The readout chain EAA names, a preamplifier (Preamp1), EPICS scalers, and the I0 flux monitors (ion chambers) the scan normalizes against, is the detection electronics. Their identities are unconfirmed and they are not separately modelled in this scaffold (DET-2).

Families

The fluorescence detector binds the EnergyDispersiveSpectrometer catalog Family, graduated once 2-ID and 7-BM shared it. The name deliberately avoids the reserved Detector Role noun (a detector is the Role an Asset plays, not its Family). The detector model and the readout chain are the detector-side open questions.
