Sample

The focusing optics that form the nano-spot and the sample stack rastered through it. PVs verified against startup/13-mll.py and 15-zp.py.

Enclosure: 3-ID-C.

Note

HXN runs two interchangeable focusing optics: a Fresnel zone plate and a crossed multilayer-Laue-lens pair. Whether both are permanently installed and operator-selected or one is decommissioned is a staff question (OPTIC-1).

Name Family PV Key specs Replaceable Status
ZonePlate ZonePlate XF:03IDC-ES Fresnel zone-plate objective (class HxnZonePlate, instance zp); the lab-frame sample axes are the FineSampleLabX pseudo-axes (zplab). Outer-zone width / diameter pending (OPTIC-2). confirm
ZonePlateAperture Aperture XF:03IDC-ES{ANC350:5 axis channels: {'x': 'XF:03IDC-ES{ANC350:5-Ax:0}Mtr', 'y': 'XF:03IDC-ES{ANC350:5-Ax:1}Mtr', 'z': 'XF:03IDC-ES{ANC350:5-Ax:2}Mtr'}
Order-sorting aperture for the zone plate (class HxnZP_OSA, instance zposa).
confirm
ZonePlateBeamStop BeamStop XF:03IDC-ES{ANC350:8 Central beam stop for the zone plate (class HxnZPBeamStop, instance zpbs). confirm
MLL_Vertical MultilayerLaueLens XF:03IDC-ES Vertical multilayer Laue lens (class HxnVerticalMLL, instance vmll). Loose family: HXN is the only sighting, distinct from ZonePlate (1D linear-zone lens, run as a crossed pair) (OPTIC-3). new confirm
MLL_Horizontal MultilayerLaueLens XF:03IDC-ES Horizontal multilayer Laue lens (class HxnHorizontalMLL, instance hmll); the crossed partner of MLL_Vertical for 2D focus. new confirm
MLLAperture Aperture XF:03IDC-ES Order-sorting aperture for the MLL (class HxnMLL_OSA, instance mllosa). confirm
SampleStage LinearStage XF:03IDC-ES{Ppmac:1 axis channels: {'ssx': 'XF:03IDC-ES{Ppmac:1-ssx}Mtr', 'ssy': 'XF:03IDC-ES{Ppmac:1-ssy}Mtr', 'ssz': 'XF:03IDC-ES{Ppmac:1-ssz}Mtr'}
Fine sample raster stage (class HxnMLLSample, instance smll): piezo ssx/ssy/ssz on the Power PMAC. These fine axes ARE the scan trajectory in a fly2d map. Coarse axes sit on ANC350:3/4.
confirm
SampleRotary RotaryStage XF:03IDC-ES{ANC350:1-Ax:0}Mtr trigger source: PSO
Tomographic rotation (sth, theta) on an Attocube ANC350; combined with the raster for nano-tomography. Hardware/encoder pending (STAGE-1).
confirm
SamplePod Hexapod XF:03IDC-ES SmarAct Smarpod 6-DOF parallel-kinematics sample pod (class SmarpodBase, single coordinated move); reuses the Hexapod family. Confirm Smarpod-to-Hexapod fit (STAGE-2). confirm
