Beamline description

LE - MOST (branch line)
The monochromator of the branch line is a modification of the GasPhase one.The main differences are:
- The maximum energy the monochromator can transmit with a usable flux is approximately 600 eV.
- Above 200 eV, it will be necessary to use the radiation emitted by the HEU undulator, which, however, is an out-of-focus source, and this should result in lower flux and resolution.
- Refocusing from the monochromator's exit slit onto the sample is achieved with a single toroidal optical element: this allows for good photon flux, but the beam divergence at the sample will be greater than with the original configuration.
- The light arrives at the sample parallel to the floor.
