Sample¶
Prime endstation¶
The Alvra Prime endstation: the sample manipulator, the optical table, the sample-view microscope, the pump-probe laser, and the von Hamos emission spectrometer.
Enclosure: Alvra.
Note
The Huber sample manipulator and the optical table fold into LinearStage and Table. The fixed-target / liquid-jet sample delivery for serial crystallography has no storage-ring analog and is deferred (SAMPLE-1). The pump-probe laser binds the catalog Laser Family (the LCLS-MFX precedent); its fs laser / X-ray synchronization (the eco lxt timing chain) is the cross-timing-domain gap CORA cannot express (LASER-1). The von Hamos spectrometer composes its crystal-translation stage (eco vonHamosBragg) with the Jungfrau detector and binds the graduated EmissionSpectrometer Family (Alvra is a fourth sighting after LCLS-MFX, ISS, and the Balder near-sighting; SPEC-1).
| Name | Family | PV | Key specs | Replaceable | Status |
|---|---|---|---|---|---|
SampleStage |
LinearStage |
SARES11-XSAM125 |
Huber sample XYZ manipulator (the eco driver derives x / y / z motors). The fixed-target / liquid-jet sample delivery on it is endstation-specific and deferred, no Family coined (SAMPLE-1) | new confirm |
|
OpticalTable |
Table |
SARES11-XOTA125 |
Prime optical table (the eco driver derives six physical motors plus virtual x / y / z / pitch / yaw axes). Reuses the Table Family | new confirm |
|
SampleMicroscope |
Camera |
SARES11-XMI125 |
on-axis sample-view microscope (focus + zoom, with appended SmarAct gonio / rotation axes); presents the Detector Role for sample viewing / alignment, binds Camera (the i13-1 side-camera precedent) | new confirm |
|
PumpProbeLaser |
Laser |
confirm: SLAAR11-LMOT (experiment laser motors: waveplate, pump delay, compressors); fs timing via the eco lxt chain (LASER-1) |
femtosecond optical pump-probe laser; binds the catalog Laser Family (the LCLS-MFX / 4-ID precedent). The delay stages are LinearStages, but the laser / X-ray fs synchronization (the eco lxt timing) is a cross-timing-domain relationship CORA cannot express (LASER-1) | new confirm |
|
LaserShutter |
Shutter |
SLAAR11-LTIM01-EVR0 |
pump-probe laser shutter, driven through a SwissFEL event receiver (EVR). Folds into Shutter; the EVR is the beam-synchronous timing system (TIMING-1) | new confirm |
|
EmissionSpectrometer |
EmissionSpectrometer |
SARES11-XCRY125 |
von Hamos X-ray emission spectrometer (XES / HERFD): a crystal-analyzer dispersive spectrometer composing the analyzer-crystal translation stage (eco vonHamosBragg, two crystal axes) with the Jungfrau detector. Binds the EmissionSpectrometer Family, graduated into the catalog (Alvra is a fourth sighting; whether each analyzer crystal is a child Asset is open, SPEC-1) | new confirm |
