Sample

The TomoWISE sample stage. Design-phase; values are TDR design targets.

The sample stage is two experiment stations in the experiment hutch, sharing one Detector gantry: a microtomography station (~45 m) and a nanotomography station (~49 m). They are modelled as two sample-stage groups in the descriptor, each presenting the specimen to the beam in a different way. Models named "(target)" are the TDR design selections, carried unbound until procurement confirms them.

Unlike the Detector, the sample stage is not modelled as a catalog Assembly here: it is a device group, not a composed Microscope-style blueprint. (2-BM models its sample positioning as a SampleTower Assembly + Fixture; TomoWISE could earn the same once the manipulator firms and a scenario registers it.) So these pages carry the containment trees but no Assembly-to-Fixture composition diagram.

The model in one picture

The kinematic stacks, base to sample (containment, Asset.parent_id). The precise sub-order firms with the mechanical design (TDR manipulator tables 9.1 / 9.5); the trees below are the design-layout intent.

Microtomography (~45 m), mirroring the standard table -> tilt -> rotary -> sample-top order:

TomoWISE  (Unit, Asset)
└── SampleTable  (Component, Family Table; base, fixed at 45 m, Xt/Yt/beta)
    ├── LaminographyTilt  (Device, TiltStage; tilts the rotation axis, alpha)
    │   └── Rotary  (Device, RotaryStage; wy, master rotation + trigger clock)
    │       ├── SamplePositioning  (Device, LinearStage; Xs/Zs, co-rotates)
    │       └── SlipRing  (Device, SlipRing; continuous-rotation feedthrough)
    ├── SampleSlit  (Device, Slit; sample-side, beam-defining)
    └── FastShutter  (Device, Shutter; sample-side)

Nanotomography (~49 m), the granite carrying the KB optics and the coarse-to-fine manipulator:

TomoWISE  (Unit, Asset)
└── NanoGranite  (Component, Family Table; granite support, ~49 m)
    ├── KB  (Device, Mirror; KB focusing pair)
    └── NanoCoarseZ  (Device, LinearStage; Zt, long-travel into the KB focus)
        └── NanoCoarseY  (Device, LinearStage; Yt, sample height)
            └── NanoCoarseX  (Device, LinearStage; Xt, centre-of-rotation)
                └── NanoTilt  (Device, TiltStage; Tilt X, axis-to-beam)
                    └── NanoRotary  (Device, RotaryStage; Rot y, continuous rotation)
                        └── NanoSamplePositioning  (Device, LinearStage; Xs/Zs, fine centring)

Microtomography endstation (~45 m)

The workhorse station: a fixed sample table about 45 m from the source carrying the rotation and positioning stack. The Rotary stage is also the trigger master clock (see Controls).

Device	Family	Target model	Design spec (TDR)
SampleTable	Table	(in-house)	fixed at 45 m, surface 390 mm below the beam; Xt +/-100 mm, Yt +50/-150 mm, beta tilt 1.2 deg
Rotary	RotaryStage	RT100AX (STAGE-1)	1200 rpm, 1 mdeg, TTL encoder 3600 pulses/rev; trigger master clock
SamplePositioning	LinearStage	XY150B-12 (STAGE-2)	Xs/Zs centring, +/-6 mm per axis, 0.1 um
LaminographyTilt	TiltStage	(target)	25 deg tilt for laminography, distinct from tomography rotation
SampleSlit	Slit	(target)	50 x 5 mm aperture; JJ X-ray IB-C50-air reference design
FastShutter	Shutter	(target)	sample-side fast shutter; Arinax Colibri (<5 ms) / Innospexion (<10 ms) references
SlipRing	SlipRing	(target)	30 to 40 channels for continuous-rotation acquisition up to 1000 rpm

Optional modules the TDR anticipates (a horizontal-rotation loading rig for in-situ mechanics, a kHz tomography module) are not yet modelled; they join as confirmed.

Nanotomography endstation (~49 m)

The high-resolution station: the KB mirror pair focuses the undulator beam for 200-nm-class cone-beam imaging. The sample manipulator is a six-axis stack on a granite support, conceptually like the microtomography endstation but about ten times more precise; it reuses the same Families (no NanoPositioner of its own). The rotary is the critical axis: its Abbe error from wobble and eccentricity must not exceed 100 nm at 100 mm sample height. Each axis names a "(target)" model carried pending procurement (NANO-1).

Device	Family	Target model	Design spec (TDR Table 9.5)
KB	Mirror	(target)	KB pair, fixed-curvature graded-multilayer; focus 205 x 196 nm @ 30 keV, 196 x 80 nm @ 45 keV
NanoGranite	Table	(target)	granite support housing the KB optics, the manipulator, and the detector stage
NanoTilt	TiltStage	Huber 5202.80	Tilt X, 2 deg, 5 mdeg; aligns the rotation axis to the beam
NanoCoarseX	LinearStage	Huber 5101.20	Xt coarse, 50 mm; CoR alignment + flat field
NanoCoarseY	LinearStage	Huber 5103.A20-90	Yt coarse, 50 to 100 mm; sample height
NanoCoarseZ	LinearStage	Zaber X-LDQ-AE	Zt long-travel, 250 to 300 mm, <0.5 um; into the KB focus, then toward the detector
NanoRotary	RotaryStage	RT100AS	Rot y, continuous, 1 mdeg, eccentricity <100 nm, TTL 3600/rev
NanoSamplePositioning	LinearStage	XY150B-12	Xs/Zs centring, +/-6 mm, 0.1 um

The KB pair and the sample manipulator are the only nano-specific hardware; the shared beam delivery and detector serve both stations.
