Sample¶
Mfx conditioning¶
The pulse picker, attenuator, channel-cut mono, focusing lenses, slits, and per-shot diagnostics that condition the beam inside the MFX hutch.
Enclosure: LCLS-MFX.
Note
The compound-refractive-lens transfocator + prefocus reuse the graduated Transfocator catalog Family (a CRL focusing optic). The pulse picker is a fast single-pulse gate folded into the Shutter Family; whether a fast pulse-picking chopper deserves its own Family is open (PULSE-1). The diamond channel-cut mono (DCCM) is used for some modes; pink-vs-mono operation is carried confirm (MONO-1).
| Name | Family | PV | Key specs | Replaceable | Status |
|---|---|---|---|---|---|
PulsePicker |
Shutter |
MFX:DIA:MMS:07 |
fast single-pulse selector; folded into the Shutter Family (a fast beam gate). Whether a rotary pulse-picking chopper is a distinct Family is open (PULSE-1) | new confirm |
|
Attenuator |
Filter |
MFX:ATT |
solid-Si binary attenuator; the existing Filter Family covers the discrete foil selection. Requesting a target transmission (the AttBase set_transmission solver, energy-dependent) is the deferred Attenuable leg; LCLS is the rule-of-three trigger for it (ATT-1) | new confirm |
|
DCCM |
Monochromator |
confirm: MFX diamond double-channel-cut mono; handles TBD (MONO-1) |
diamond double-channel-cut monochromator for monochromatic / spectroscopy modes; MFX also runs pink/SASE beam mono-out (MONO-1) | new confirm |
|
Transfocator |
Transfocator |
MFX:LENS |
compound-refractive-lens (Be) transfocator stack; reuses the graduated Transfocator catalog Family (a CRL focusing optic). Selecting a lens set for a target focal length is a transmission/focus solver, like the attenuator (ATT-1) | new confirm |
|
Prefocus |
Transfocator |
MFX:DIA:XFLS |
upstream X-ray focusing lens set (prefocus CRL); reuses the graduated Transfocator catalog Family (a CRL focusing optic) | new confirm |
|
MFXSlits |
Slit |
MFX:DG1:JAWS |
DG1 4-blade slits | new confirm |
|
MFXSlitsDownstream |
Slit |
MFX:DG2:JAWS:US |
DG2 slit set (upstream/midstream/downstream blades) | new confirm |
|
MFXIntensityMonitor |
FluxMonitor |
MFX:DG1:IPM |
intensity-position monitor (DG1); flux + position Sensor; loose families reused (DIAG-1) | new confirm |
|
MFXImager |
Scintillator |
MFX:DG1:PIM |
DG1 profile imager (YAG + camera) | new confirm |
|
TimeTool |
Diagnostic |
MFX:ATM |
arrival-time monitor (X-ray/optical-laser timing jitter); presents the Sensor Role; loose family reused (DIAG-1). It exists to drift-correct the fs pump-probe delay, which CORA has no model for (LASER-1, DAQ-1) | new confirm |
|
Wave8 |
FluxMonitor |
MFX:DG1:MMS:08 |
fast per-shot intensity / wavefront diagnostic; presents the Sensor Role; loose family reused (DIAG-1) | new confirm |
Mfx endstation¶
The sample-interaction point: sample delivery and the X-ray emission spectrometer.
Enclosure: LCLS-MFX.
Note
Sample delivery at MFX is a liquid jet / fixed target (serial femtosecond crystallography), with no storage-ring analog; it is deferred (SAMPLE-1). The von Hamos spectrometer is a crystal-analyzer X-ray emission spectrometer (it composes analyzer crystals + a 2D detector along a dispersive geometry). It introduced the EmissionSpectrometer family, which GRADUATED into the catalog once NSLS-II ISS (8-ID) earned the second sighting (the Johann + von Hamos XES / HERFD spectrometers); the same gap appeared at MAX IV Balder (SCANIA-2D). Whether each analyzer crystal is a child Asset is still open (SPEC-1).
| Name | Family | PV | Key specs | Replaceable | Status |
|---|---|---|---|---|---|
PumpProbeLaser |
Laser |
confirm: LAS:FS45 (laser timing) + MFX:LAS:MMN:* (delay / waveplate motors) |
femtosecond optical pump-probe laser; binds the catalog Laser Family (the 4-ID precedent, model-vs-hazard open, SAMPLE-1). The delay stage is a LinearStage, but the laser/X-ray fs synchronization (the lxt_ttc SyncAxis, ~50 fs deadband) is a cross-timing-domain relationship CORA cannot express (LASER-1) | new confirm |
|
LiquidJet |
MFX:LJH |
Beckhoff-controlled liquid-jet sample delivery (serial crystallography); also a fixed-target option. Sample-delivery is endstation-specific and deferred (SAMPLE-1); no Family is coined yet | new confirm |
||
EmissionSpectrometer |
EmissionSpectrometer |
MFX:SPEC |
von Hamos 6-crystal X-ray emission spectrometer (XES / HERFD): a crystal-analyzer dispersive spectrometer composing analyzer crystals + a 2D detector, distinct from a Monochromator. Binds the EmissionSpectrometer family, which it introduced and which GRADUATED into the catalog once NSLS-II ISS (8-ID) earned the second sighting (SPEC-1) | new confirm |
