Detector¶

7-BM runs several detector modalities, not the single 2D camera path of the 2-BM micro-CT pilot: an indirect-imaging camera for tomography, a high-speed movie camera, a point photodiode for time-resolved radiography, and an energy-dispersive detector for diffraction.

Enclosure: 7-BM-B.

Note

The tomography path (scintillator plus visible optics plus area camera) reuses the 2-BM detector shape and could later compose the cross-facility Microscope Assembly; it is left as plain devices in this scaffold. The point photodiode and the energy-dispersive detector both present the Sensor Role (a scalar or short-vector Reading, not a 2D frame); they are bound to loose family names pending the decision on whether each is a new catalog Family or a deployment-local Sensor device.

Name	Family	Key specs	Status
`Scintillator`	`Scintillator`	scintillator crystal for indirect x-ray imaging; subject to thermal cracking under white beam (high_speed_imaging.rst)	`new` `confirm`
`TomographyCamera`	`Camera`	area camera coupled to the scintillator through visible optics for tomography and radiographic imaging	`new` `confirm`
`HighSpeedCamera`	`Camera`	high-speed movie camera (Photron Nova S16 in the docs); captures short movie bursts, one per chopper opening, hardware-gated by the DG645 timing chain and optionally synced to the storage ring at 271 kHz. The acquisition unit (one burst as one Run / Dataset) and top-up blanking are open (HSI-1).
	`new` `confirm`
`Photodiode`	`Photodiode`	PIN photodiode for time-resolved radiography (focused beam, ~8 keV); presents the Sensor Role (a scalar intensity Reading), read out through a high-speed digitizer (ADQ14) or oscilloscope plus the DataGrabber program, not as a camera frame. The detector Family question and the data unit (one trace as one Dataset) are open (RAD-1).
	`new` `confirm`
`EnergyDispersiveSpectrometer`	`EnergyDispersiveSpectrometer`	germanium energy-dispersive detector for energy-dispersive diffraction; records a per-photon energy spectrum (an MCA histogram), not a 2D frame, and presents the Sensor Role. Binds the catalog EnergyDispersiveSpectrometer Family (graduated once 2-ID and 7-BM shared it). Whether this is the same physical detector as the fluorescence MCA is open (DET-1).
