Detector¶
The simultaneous SAXS and WAXS Pilatus area detectors, the SAXS camera-length stage and beamstops, the flux monitor, the fluorescence detector, and the beam-viewing cameras. PVs verified against smibase/pilatus.py, beamstop.py, electrometers.py, amptek.py, prosilica.py.
Enclosure: 12-ID-C.
Note
SMI's measurement is the scattering pattern on two Pilatus detectors read at once: the SAXS 2M down the in-vacuum flight path and the WAXS 900KW on a swing arc. For GISAXS the WAXS arc is swung out; the detector stage sets the SAXS camera length (the accessible Q). All reuse existing families. Which detectors are live versus the retired set (a 1M, a 300KW) is a staff question (DET-1).
| Name | Family | PV | Key specs | Replaceable | Status |
|---|---|---|---|---|---|
SAXSDetector |
Camera |
XF:12ID2-ES{Pilatus:Det-2M} |
Pilatus 2M SAXS area detector (pil2M) down the in-vacuum flight path; reuses Camera. Note the odd XF:12ID2-ES IOC namespace. | confirm |
|
WAXSDetector |
Camera |
XF:12IDC-ES:2{Det:900KW} |
Pilatus 900KW WAXS area detector (pil900KW) on a swing arc (XF:12IDC-ES:2{WAXS:1-Ax:Arc}), read simultaneously with the SAXS detector; swung out for GISAXS, to zero for GIWAXS. Reuses Camera. | confirm |
|
SAXSDetectorStage |
LinearStage |
XF:12IDC-ES:2{Det:1M-Ax: |
SAXS detector translation (x / y / z; the Z sets the sample-to-detector camera length and hence the accessible Q). Reuses the legacy Det:1M motor namespace from the retired 1M detector. Reuses LinearStage. | confirm |
|
SAXSBeamStop |
BeamStop |
XF:12IDC-ES:2{BS:SAXS-Ax: |
SAXS beamstop assembly (saxs_bs; rod and pin-diode beamstops IBB / IBM / OBB / OBM) blocking the direct beam. The WAXS detector has its own beamstop motor (XF:12ID2C-ES{MCS:2-Ax:1}Mtr). Reuses BeamStop. | confirm |
|
FluxMonitor |
FluxMonitor |
XF:12ID:2{EM:Tetr1} |
TetrAMM pin-diode flux monitor (pin_diode, QuadEM) reading incident intensity for normalization; reuses FluxMonitor (graduated #353). Channel map pending (DIAG-1). | confirm |
|
FluorescenceSpectrometer |
EnergyDispersiveSpectrometer |
XF:12IDC-ES:2{Det-Amptek:1} |
Amptek energy-dispersive fluorescence MCA (amptek) for element-sensitive work; reuses EnergyDispersiveSpectrometer (graduated #345). | confirm |
|
BeamViewingCamera |
Camera |
XF:12IDC-BI{Cam:SAM} |
On-axis sample-viewing camera (OAV, a Prosilica; a HEX top camera XF:12IDC-BI{Cam:HEX} and FOE diagnostic cameras FS / WBStop / VFM serve alignment). Reuses Camera. Live set pending (CAM-1). | confirm |
