Source¶
The incident beam, produced, conditioned, and defined before the sample. A walk along the source-stage devices; the sample and detection stages are documented as their own composed-fixture pages, the controllers that drive these devices are on the Controls page, and the supplies they draw on are in Operations. Each device pairs its human name with the EPICS handle, its key specs, and whether it is field replaceable. new marks a device not yet modeled in CORA; confirm marks a value taken from the docs that staff have not yet verified.

| Property | Value |

| Facility | nsls2 |
| Sector | Sector 17 |
| Tier | Unit |
| Source | insertion-device (confirm: AMX (17-ID-1) shares its IVU21 in-vacuum undulator (SR:C17-ID:G1{IVU21:1}) and the 17-ID straight with its sibling FMX (17-ID-2, which uses IVU21:2); modelled as one root Unit feeding the 17-ID-1 branch (the FMX / CSX precedent), not two roots. Undulator period and gap range not fully in the profile collection (SRC-1, TOPO-1).) |
Enclosures¶
| Enclosure | Role | Facility | Permit signal |
|---|---|---|---|
17-ID-A |
optics-hutch | nsls2 |
confirm: PSS search-and-secure permit leaf and the shutter PVs are not in the profile collection; the front end is shared with FMX (PSS-1, TOPO-1) |
17-ID-B |
experiment-hutch | nsls2 |
confirm: PSS permit leaf unknown; 17-ID-B (PV zone XF:17IDB) is the AMX experiment enclosure carrying the KB mirrors, the goniometer, the robot, and the Eiger (PSS-1) |
Source¶
The shared 17-ID insertion device, the front-end and photon shutters, and the high-heat-load slit.
Enclosure: 17-ID-A.

InsertionDevice |
SR:C17-ID:G1{IVU21:1} |
IVU21 in-vacuum undulator on the NSLS-II 3 GeV ring (ring current SR:OPS-BI{DCCT:1}I:Real-I), shared with FMX (17-ID-2, IVU21:2) on the 17-ID straight; AMX drives gap index :1. Gap axis SR:C17-ID:G1{IVU21:1-Ax:Gap}-Mtr. Period and range not fully in source (SRC-1, TOPO-1). | confirm |

Shutter |
confirm: shared FMX / AMX front-end (FOE) photon shutter; PV not in the profile collection (PSS-1) Front-end photon shutter (not exposed in the profile collection). |

FrontEndSlit |
Slit |
FE:C17A-OP{Slt |
Front-end white-beam slit (FE:C17A-OP{Slt:1 / Slt:2 / Slt:12 blades and center / gap) defining the accepted beam, shared with FMX. | confirm |
|
HighHeatLoadSlit |
Slit |
XF:17IDA-OP:AMX{Slt:0 |
High-heat-load white-beam slit ahead of the monochromator. | confirm |
Optics¶
Condition the beam and set its energy: the vertical double-crystal monochromator, the tandem-deflection harmonic-rejection mirrors and the KB focusing pair, the beam-conditioning attenuator, and the slits. PVs verified against the amx-profile-collection startup files.
Enclosure: 17-ID-A.
| Name | Family | PV | Key specs | Replaceable | Status |
|---|---|---|---|---|---|
Monochromator |
Monochromator |
XF:17IDA-OP:AMX{Mono:DCM |
Vertical double-crystal monochromator (VDCM; Bragg / gap / pitch / roll / W axes XF:17IDA-OP:AMX{Mono:DCM-Ax:B/G/P/R/W}Mtr and an energy axis XF:17IDA-OP:AMX{Mono:DCM-Ax:E}Mtr). The vertical geometry is the AMX-vs-FMX difference (FMX is horizontal). Reuses the Monochromator family. Crystal cut and energy range pending (DCM-1). | confirm |
|
TandemMirror |
Mirror |
XF:17IDA-OP:AMX{Mir:TDM |
Tandem-deflection mirror pair (TDM; pitch / roll / X / Y up-and-down-stream axes) for harmonic rejection and steering, AMX's analog of FMX's horizontal focusing mirror. Reuses the Mirror family (KB-1). | confirm |
|
KBMirrors |
Mirror |
XF:17IDB-OP:AMX{Mir |
Kirkpatrick-Baez microfocus mirror pair (horizontal KBH with P/R/X/Y axes, vertical KBV with P/X/Y, XF:17IDB-OP:AMX{Mir:KBH / KBV-Ax:...}Mtr) focusing the microbeam at the sample, with a piezo tweaker. Reuses the Mirror family (KB-1). | confirm |

BeamConditioningAttenuator |
Filter |
XF:17IDB-OP:AMX{Attn:BCU |
Beam-conditioning-unit attenuator (BCU; four insertable absorber foils XF:17IDB-OP:AMX{Attn:BCU-Ax:1-4}Mtr solving a foil combination for a requested transmission XF:17IDB-OP:AMX{Attn:BCU}). Reuses the Filter family; the energy-dependent transmission solver is the deferred Attenuable leg (the LCLS-MFX ATT-1 precedent). Unlike FMX, AMX has no CRL transfocator in source. | confirm |

ExperimentSlits |
Slit |
XF:17IDB-OP:AMX{Slt:2 |
Beam-defining slits in the experiment enclosure (XF:17IDB-OP:AMX{Slt:2 / Slt:3 / Slt:4}); a first slit station sits at XF:17IDA-OP:AMX{Slt:1} in the FOE. Reuses the Slit family. | confirm |
|
EnergyAxis |
PseudoAxis |
The master energy axis: a pseudopositioner coordinating the undulator gap, the VDCM, and the mirrors from per-energy look-up tables (the set_energy plan). Energy is set for the experiment and scanned for anomalous (SAD / MAD) data collection; the MX technique scope is TECH-1. | confirm |
