Sample

The sample positioning table and the sample-environment translation stack at 10-ID-D. First cut; PVs read from the profile collection, carried confirm.

The IXS sample side is a hard X-ray ambient endstation: pure-translation stacks set the sample position in front of the six-circle spectrometer, which swings about the sample to set the momentum transfer Q. They are modelled as sample-stage groups in the descriptor.

Both stacks bind the catalog LinearStage Family (the fxi / hxn SampleStage precedent for a pure-translation stage). This is deliberately not SIX's loose Manipulator: that Family is a UHV cryostat multi-axis manipulator, and reusing it for an ambient hard X-ray endstation would mirror context, not anatomy.

The sample stack (10-ID-D)

Device	Family	Design spec / note
SampleTable	LinearStage	sample positioning table (x/y/z) on the Spec:1 PV root (SAMPLE-1)
SampleEnvironment	LinearStage	sample-environment translation stack (x/y/z) on its own Env:1 PV root (SAMPLE-1)

The sample table sets the sample position in the beam; the environment stack translates whatever sample environment is mounted, on its separate Env:1 PV root. Together they place the sample at the centre of rotation the six-circle arm pivots about. The arm itself (the Spectrometer Goniometer and its reciprocal-space pseudo-axis) lives on the Detector side, since at IXS the scattering geometry sets Q and the analyzed beam is point-detected there.

Whether the table and the environment translations are one fused Asset or two siblings on their separate PV roots, and what sample environment is mounted on them, is SAMPLE-1.
