Bernina endstation

The Bernina diffraction endstation: the GPS six-circle diffractometer, the XRD You-geometry diffractometer, the downstream-diagnostic table, the pump-probe laser, and the sample-view cameras.

Enclosure: Bernina.

Note

The defining endstation. GPS (SARES22-GPS, a six-circle station) and XRD (SARES21-XRD, a You-geometry station with a kappa goniometer, a 2-theta detector arm, a polarization- analyzer branch, a heavy-load goniometer table, and a PI hexapod) are both reconfigurable diffraction PLATFORMS. Each reuses the graduated Diffractometer ASSEMBLY (4-ID / 8-ID): it COMPOSES a Goniometer (the sample circles + x/y/z, one Asset), zero-or-more RotaryStage detector-arm circles, and a reciprocal-space PseudoAxis. So each platform is modelled here as a Goniometer Asset + a PseudoAxis Asset, with the Assembly composition designed on model.md (DIFF-1); NO new Family is coined. WHICH sub-assemblies (base/arm/polana/kappa/ heavy-load/hexapod/robot) are actually mounted is read from the non-public bernina_config JSON and is carried unknown (CONFIG-1). The Staeubli TX200 robot (over PShell HTTP, not EPICS) handling samples / the detector is deferred (ROBOT-1). The fs pump-probe laser binds the catalog Laser Family; its fs sync (the eco lxt chain) is the cross-timing- domain gap (LASER-1).

Name	Family	PV	Key specs	Replaceable	Status
GPS_Goniometer	Goniometer	SARES22-GPS	the GPS six-circle diffractometer's sample-orientation goniometer (eco gps, GPS; recspace SixCircleBernina). The sample-orientation circles + x/y/z bind the Goniometer Family; the full platform is the Diffractometer Assembly (DIFF-1)		new confirm
GPS_ReciprocalSpace	PseudoAxis	confirm: GPS reciprocal-space pseudo-axis (eco SixCircleBernina recspace conversion); the partition rule is DIFF-2	the GPS six-circle reciprocal-space (hkl) pseudo-axis layer; the reciprocal_space slot of the Diffractometer Assembly (DIFF-1, DIFF-2)		new confirm
XRD_Goniometer	Goniometer	SARES21-XRD	the XRD You-geometry diffractometer's sample-orientation goniometer (eco xrd, XRDYou). Recoverable axes: base (gamma/mu + translations/tilts), arm (delta/tdet), polana (pol/pthe/ptth), kappa (with kappa<->Eulerian conversion), heavy-load table, PI hexapod; WHICH are mounted is external (CONFIG-1). Binds the Goniometer Family; the platform is the Diffractometer Assembly (DIFF-1)		new confirm
XRD_DetectorArm	RotaryStage	confirm: XRD 2-theta detector arm (eco xrd delta = SARES21-XRD:MOT_DT_RX2TH); the detector_arm slot of the Diffractometer Assembly (DIFF-1)	the XRD detector-arm 2-theta circle (delta); the ZeroOrMore detector_arm slot of the Diffractometer Assembly (DIFF-1). Axis suffix recoverable, mount state external (CONFIG-1)		new confirm
XRD_ReciprocalSpace	PseudoAxis	confirm: XRD reciprocal-space pseudo-axis (eco diffcalc, Crystals recspace; kappa<->You conversion); the partition rule is DIFF-2	the XRD reciprocal-space (hkl) pseudo-axis layer (eco diffcalc); the reciprocal_space slot of the Diffractometer Assembly (DIFF-1, DIFF-2)		new confirm
USDTable	Hexapod	confirm: upstream-diagnostic / sample hexapod table (eco usd_table, HexapodSymmetrie; 6-axis)	the upstream sample / diagnostic hexapod table; folds into the Hexapod Family		new confirm
SampleCamera	Camera	SARES20-CAMS142-C1	below-sample view microscope (eco samplecam_below, MicroscopeMotorRecord; zoom on SARES20-MF1:MOT_14); presents the Detector Role for sample viewing / alignment, binds Camera		new confirm
PumpProbeLaser	Laser	SLAAR21-LMOT	femtosecond optical pump-probe laser (eco las, LaserBernina); binds the catalog Laser Family (the Alvra / LCLS-MFX precedent). The laser / X-ray fs synchronization (the eco lxt chain) is the cross-timing-domain gap (LASER-1)		new confirm
LaserShutter	Shutter	SLAAR21-LTIM01-EVR0	pump-probe laser shutter (eco laser_shutter), driven through a SwissFEL event receiver (EVR). Folds into Shutter; the EVR is the beam-synchronous timing system (TIMING-1)		new confirm
