Sample¶
The Arinax MD3 microdiffractometer goniometer that holds and orients the crystal, the cryostream sample cooling, and the beamstop. As at TPS 07A, the MD3 is reached as EPICS PVs through the DCSS / DHS bridge (no separate transport).
Enclosure: TPS-05A-EH.
Note
TPS 05A holds a cryocooled crystal on the MD3 microdiffractometer and rotates it through an oscillation while the EIGER2 X 9M reads frames, the same shape as TPS 07A. The MD3 goniometer reuses the graduated Goniometer family (the i03 / 07A / MX3 MX precedent). It is reached through the EPICS Device Handler Server (the 07A pattern, applied to the cluster per the J. Synchrotron Rad. 2025 paper), so it is on the EPICS floor; the DCSS server orchestrates the oscillation above that floor. The ISARA sample robot is modelled as a deferred Procedure (sample exchange), not a device, per the i03 / i24 / 07A / MX3 ROBOT-1 precedent.

Goniometer |
Goniometer |
Arinax MD3 microdiffractometer goniometer with a mini-kappa: omega rotation plus kappa / phi, sample centring, and alignment. Reuses the graduated Goniometer family. Reached as EPICS PVs via the DHS bridge (the inferred 05a-ES: endstation namespace); axis PV records pending (GONIO-1, PV-1). | confirm |
