Detector¶
The multi-element fluorescence detectors that make the XRF maps, and the scaler-counted flux channels. PVs verified against the xfm-profile-collection startup files.
Enclosure: 4-BM-C.
Note
Which detector is read sets the mapping mode: the Xspress3 silicon-drift detector for step / fly XRF mapping, or the Maia array for fast continuous mapping. Both bind the catalog EnergyDispersiveSpectrometer. The scaler counts the I0 flux channels for normalization.

EnergyDispersiveSpectrometer |
XF:04BMC-ES{x3m:1}: |
Four-channel silicon-drift fluorescence detector read by an Xspress3 mini (XF:04BMC-ES{x3m:1}: channels C1-C4, per-channel ROIs, an HDF5 stream). The primary XRF-mapping detector; reuses the EnergyDispersiveSpectrometer family. Element count and ROI map to confirm (DET-1). | confirm |

EnergyDispersiveSpectrometer |
XFM:MAIA |
confirm: the Maia continuous-mapping detector array (XFM:MAIA); read from the bypass profile (rvt/bypass40-maia.py), not the active startup. Element count and live status to confirm (MAIA-1) The Maia 384-element detector array for fast continuous (fly-scan) XRF mapping, XFM's signature mapping capability. Reuses the EnergyDispersiveSpectrometer family (a large continuous-readout array variant). Carried from the bypass profile (MAIA-1). |

XF:04BM-ES:2{Sclr:1} |
The SIS3820 scaler (XF:04BM-ES:2{Sclr:1}) counting the I0 / flux channels for per-pixel normalization. Reuses the FluxMonitor family. The full channel map to confirm (DIAG-1). | confirm |
