Sample¶
The endstation beam-conditioning slits that define the coherent beam at the sample, the grazing-incidence mirror for GISAXS, the sample stack, and the sample-environment thermal stage. PVs verified against startup/10-optics.py, 80-pseudomotors.py, 51_Linkam.py.
Enclosure: 11-ID-B.
Note
CHX positions the sample in a coherent focused spot and records speckle time series (XPCS). The beam-defining and guard slits in the endstation are the coherence-conditioning hardware: they trim the beam to the coherent core and block parasitic scatter ahead of the sample. The grazing-incidence mirror steers the beam onto a surface for GISAXS; the sample stack reuses LinearStage; the Linkam stage reuses the TemperatureController family for in-situ studies.

BeamDefiningSlit |
Slit |
XF:11IDB-OP{Slt:BDS-Ax: |
Endstation beam-defining slit (s2, a SmarAct slit, class VirtualMotorSlits) trimming the beam to its coherent core at the sample; reuses the Slit family. It replaced an older large JJ slit (Slt:2). This is the coherence-defining slit for XPCS. | confirm |
|
GuardSlit |
Slit |
XF:11IDB-OP{Slt:Guard-Ax: |
Guard slit (gsl, a SmarAct slit) cleaning up parasitic scatter from the beam-defining slit ahead of the sample; reuses the Slit family. | confirm |
|
GrazingIncidenceMirror |
Mirror |
XF:11IDB-OP{Mir:GI-Ax: |
Grazing-incidence mirror (gi, class XYThetaMotor) steering the beam onto a surface for GISAXS; reuses the Mirror family. Whether GISAXS is a live routine is GI-1. | confirm |
|
SampleStage |
LinearStage |
XF:11IDB-ES{Dif-Ax: |
Sample stack on the diffractometer base (diff, class Diffractometer at XF:11IDB-ES{Dif; physical_sample_holder XF:11IDB-ES{Dif-Ax:XH}Mtr, driven by the SamplePositioner pseudomotor). Bound to LinearStage as a design-phase placeholder; the diffractometer also carries goniometric axes, so whether its sample orientation is modelled as a Goniometer plus a Diffractometer Assembly (the 8-ID precedent) is folded into STAGE-1. Full axis set pending (STAGE-1). | confirm |
|
SampleTemperature |
TemperatureController |
XF:11ID-ES{LINKAM}: |
Linkam thermal stage (LThermal) with a tensile variant (LTensile) for in-situ studies; reuses the TemperatureController family (graduated #350). | confirm |
