Sample¶
The Arinax MD3 microdiffractometer goniometer that holds and orients the crystal, the cryostream sample cooling, and the beamstop. The MD3 is reached as EPICS PVs through the DCSS / DHS bridge (no separate transport, unlike MX3's Exporter).
Enclosure: TPS-07A-EH.
Note
TPS 07A holds a cryocooled crystal on the MD3 microdiffractometer and rotates it through an oscillation while the EIGER2 reads frames. The MD3 goniometer reuses the graduated Goniometer family (the i03 / MX3 MX precedent). Unlike MX3 (which drives the MD3 over the MXCuBE Exporter protocol), 07A reaches the MD3 through the EPICS Device Handler Server, so it is on the EPICS floor; the DCSS server orchestrates the oscillation above that floor (the seam CORA replaces). The ISARA sample robot is modelled as a deferred Procedure (sample exchange), not a device, per the i03 / i24 / MX3 ROBOT-1 precedent.

Goniometer |
Goniometer |
Arinax MD3 microdiffractometer goniometer with a mini-kappa: omega rotation plus kappa / phi, sample centring (CentringX / Y), and alignment (AlignmentX / Y / Z). Reuses the graduated Goniometer family. Reached as EPICS PVs via the DHS bridge (07a-ES: endstation namespace); per-axis PV records pending (GONIO-1). | confirm |

SampleTemperature |
TemperatureController |
Cryostream sample cooling keeping the crystal at cryogenic temperature through the dataset. Reuses the TemperatureController family (graduated #350); PV and vendor pending (ENV-1). | confirm |

BeamStop |
BeamStop |
Beamstop blocking the direct beam at the sample. Reuses BeamStop; PV pending (DIAG-1). | confirm |
