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 (SARUN03-15); photon energy is set per-shot, the setpoint limited to 5000-13000 eV in slic, and the same source feeds the Alvra, Bernina, and Cristallina stations one at a time (SRC-1 / TOPO-1). The undulator period (15 mm) and the K-to-energy constants are in slic; the gap tables and source size are not, and are carried confirm (SRC-1). |

Undulator source¶
The SwissFEL Aramis free-electron-laser source, its front-end gas pulse-energy monitors, and the photon single-shot spectrometer.
Enclosure: Aramis-Optics-SAROP31.
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 (SRC-1). The photon single-shot spectrometer (PSSS) measures the per-shot spectrum; it presents the Sensor Role (loose Diagnostic).

Front end¶
The shared front-end slit, attenuator, and profile monitor that gate and condition the beam before the SAROP31 optics.
Enclosure: Aramis-Optics-SAROP31.
Note
The front-end attenuator is a solid attenuator solving an energy-dependent foil combination (the slic aramis_attenuator); the Filter Family covers the discrete selection, the solve is the deferred Attenuable leg (ATT-1).

Aramis optics¶
The SAROP31 Aramis optics: the offset mirrors, the double-channel-cut monochromator, the slits, the pulse picker, the experiment attenuator, the KB focusing mirrors, the alignment laser, and the intensity / profile monitors that condition and focus the beam onto the Cristallina sample.
Enclosure: Aramis-Optics-SAROP31.
Note
The offset mirrors and the KB pair fold into Mirror. The monochromator is a DOUBLE CHANNEL-CUT (DCCM, ODCC110), distinct from Bernina's double-crystal mono (ODCM098); it folds into Monochromator, and Cristallina also runs pink / SASE beam mono-out (the mono screen selects out / mono / pink) (MONO-1). The X-ray pulse picker is a fast single-pulse gate folded into Shutter (PULSE-1). The only laser in the optics is the X-ray ALIGNMENT laser (OLAS147), a catalog Laser Family device, NOT a pump-probe laser (LASER-1).
