Sample¶
The micro-goniometer, the automated sample-changing robot, the on-axis viewing and illumination, and the sample cooling. PVs verified against the fmx-profile-collection startup files.
Enclosure: 17-ID-C.
Note
FMX mounts cryo-cooled protein crystals on a single-omega micro-goniometer with x/y/z centring and PI fine stages, exchanged by a robot from a dewar. The goniometer reuses the graduated Goniometer family; the robot is one Positioner Asset (not a new Family); the on-axis illumination binds the catalog Backlight Family. Sample cryo-cooling (the cold-gas cryostream) is not exposed in the profile collection (an annealer / thaw-air actuator XF:17IDC-ES:FMX{Wago:} is), so it is deferred (CRYO-1).
| Name | Family | PV | Key specs | Replaceable | Status |
|---|---|---|---|---|---|
Goniometer |
Goniometer |
XF:17IDC-ES:FMX{Gon:1 |
The MX micro-goniometer (single omega rotation XF:17IDC-ES:FMX{Gon:1-Ax:O}Mtr plus GX / GY / GZ sample-centring and PY / PZ pin stages, with PI fine X / Y / Z scanners). Reuses the Goniometer family (graduated on the i03 Smargon); per-axis decomposition and centre-of-rotation calibration pending (GONIO-1). | confirm |
|
Robot |
XF:17IDC-ES:FMX{Gov:Robot} |
Automated sample-changing robot, coordinated by the LSDC Governor state machine (XF:17IDC-ES:FMX{Gov:Robot}, with a dewar / puck safety interlock XF:17IDC-OP:FMX{DewarSwitch}). Per the i03 / 19-BM precedent: one Positioner-presenting Asset loading / unloading a Subject, gated by a Clearance, vendor in a bound Model; NOT a new SampleChanger Family. The exchange workflow and Subject custody lifecycle are deferred (ROBOT-1). | confirm |

Backlight |
Backlight |
XF:17IDC-ES:FMX{Light:1 |
On-axis sample illumination (ring light) for loop centring. Binds the catalog Backlight Family (graduated across the MX / imaging fleet, DET-1). | confirm |
|
SampleCamera |
Camera |
XF:17IDC-ES:FMX{Cam:7} |
On-axis sample-viewing camera (a Prosilica; a second on-axis camera XF:17IDC-ES:FMX{Cam:8} and several focus-screen cameras XF:17IDx-BI:FMX{FS:n-Cam:1} serve alignment). Reuses the Camera family. | confirm |
