Source¶
The incident beam, produced, conditioned, and defined before the sample. The controllers that drive these devices are on the Controls page. Each device pairs its human name with its control 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.

| Source | free-electron-laser (confirm: SASE hard-X-ray FEL on the shared SwissFEL Aramis undulator line; photon energy is set per-shot and the same source feeds the Alvra, Bernina, and Cristallina stations one at a time (SRC-1 / TOPO-1). The Aramis undulator parameters are not in the eco manifest and are carried confirm. |

Undulator source¶
The SwissFEL Aramis free-electron-laser source and its front-end pulse-intensity monitors.
Enclosure: Aramis-Optics-SAROP21.
Note
SwissFEL is a linac-driven FEL, not a storage ring; machine beam is carried as a PhotonBeam Supply (MACHINE-1). The Aramis undulator photon energy is set per shot; CORA has no per-shot energy setpoint, and the undulator-as-driven-source is deferred (SRC-1). The undulator parameters are absent from the eco manifest (SRC-1).

Undulator |
InsertionDevice |
confirm: SwissFEL Aramis undulator line; per-segment handles not in eco (SRC-1) |

GasMonitor |
FluxMonitor |
confirm: SwissFEL Aramis gas detector (eco mon_und_gas; no PV passed inline) |
gas intensity monitor; FEL pulse-energy diagnostic, presents the Sensor Role; loose family reused. Per-shot pulse energy is correlated in the DAQ by pulse-ID (DAQ-1) | new confirm |

FrontEndIntensityMonitor |
FluxMonitor |
SARFE10-PBPS053 |
solid-target intensity / position monitor after the undulator (PBPS); presents the Sensor Role for flux (FluxMonitor) and position (Diagnostic, loose) | new confirm |
Front end¶
The front-end and safety shutters, the undulator slit, and the front-end attenuator that gate and condition the beam before the SAROP21 optics.
Enclosure: Aramis-Optics-SAROP21.
Note
The photon and safety shutters fold into the Shutter Family; their permit binding to the PSS is not in eco (PSS-1). The front-end attenuator is a solid attenuator solving an energy-dependent foil combination (AttenuatorAramis); the Filter Family covers the discrete selection, the solve is the deferred Attenuable leg (ATT-1).

Aramis optics¶
The SAROP21 Aramis optics: the offset mirrors, the double-crystal monochromator, the switchyard and mono slits, the X-ray pulse picker, the attenuator, the KB focusing mirrors, the PSEN timing diagnostic, and the profile / intensity monitors that condition and focus the beam onto the Bernina sample.
Enclosure: Aramis-Optics-SAROP21.
Note
The offset mirrors and the KB pair fold into Mirror. The double-crystal monochromator (ODCM098) folds into Monochromator; Bernina also runs pink / SASE beam with the mono out (MONO-1). The X-ray pulse picker is a fast single-pulse gate folded into Shutter (PULSE-1). The PSEN spectral-encoder measures the X-ray-to-laser arrival time; it presents the Sensor Role (loose Diagnostic) but exists to drift-correct the fs pump- probe delay (LASER-1). One live Bernina profile monitor (prof_mirr_alv1) carries an Alvra-line PV (SAROP11-PPRM066); carried confirm (XREF-1).
