Sample¶
The diffractometer that holds the sample and detector arm, the sample-array stage, the beam-defining pinhole, and the sample-environment thermal stages. PVs verified against startup/10-motors.py and 11-temperature-controller.py.
Enclosure: 28-ID-C.
Note
XPD positions a powder or capillary sample in the high-energy beam and records the diffraction / total-scattering pattern on the area detector. The sample stack reuses LinearStage; the rich sample-environment cluster (cryostream, furnace, hot-air blower) reuses the TemperatureController family, the same one Diamond i11 graduated for variable-temperature powder diffraction.
| Name | Family | PV | Key specs | Replaceable | Status |
|---|---|---|---|---|---|
SampleStage |
LinearStage |
XF:28IDC-ES:1{Dif:1-Ax: |
Sample and detector-arm diffractometer (diff, Dif:1: Th, X, Y, two-theta inboard/outboard). Bound to LinearStage as a design-phase placeholder; the diffractometer carries goniometric axes, so whether its orientation is modelled as a Goniometer plus a Diffractometer Assembly (the 8-ID / i11 precedent) is folded into STAGE-1. | confirm |
|
SampleArrayStage |
LinearStage |
XF:28IDC-ES:1{SampArray-Ax: |
Sample-array stage (sample_x / sample_y) presenting many samples for high-throughput acquisition, plus a secondary sample stage (Stg:Smpl2). Reuses LinearStage. | confirm |
|
Pinhole |
Aperture |
XF:28IDC-ES:1{PinHole:XRD-Ax: |
Beam-defining pinhole (pinhole_x / pinhole_y) cleaning the beam onto the sample; reuses the Aperture family. | confirm |
|
SampleTemperature |
TemperatureController |
XF:28IDC-ES:1{CS:800} |
Sample-environment thermal control: the cs700 (XF:28IDC-ES:1{Env:01}) and cs800 (XF:28IDC-ES:1{CS:800}) cryostream controllers, Eurotherm and hot-air blowers (Env:03 / 04 / 06), a Lakeshore cryostat (XF:28IDC-ES1:LS335:{CryoStat}), and a Linkam furnace (XF:28IDC-ES:2:{LINKAM}:). The cs700 / cs800 are understood to be Oxford Cryostreams (inference, not in source; TEMP-1). Modelled as one thermal-environment Asset; reuses TemperatureController (graduated by Diamond i11, #350). Which units are live is TEMP-1. | confirm |
