HOMS

The Homs (Hard X-ray Offset Mirror System) consists of two flat mirrors, H1M and H2M.The purpose of the offset mirror system is to parallel-offset the beam, using mirrors that are designed to reflect a particular x-ray wavelength range. The highest energy spontaneous radiation would go into or through the mirror, to be absorbed by some material, to stop it from going beyond the FEE. The hard x-ray line is offset by about 30 millimeters. The mirrors have two degrees of freedom The entire mirror can be moved in the X direction, and the mirror can be rotated about its Y axis. Mirrors M1H and M2H, for the hard x-rays, are normally not moved once they are aligned.

For the hard x-ray mirrors, the angle is 1.350 milliradians ±0.025 milliradians.

Its alignment relies on several imagers before, inbetween, and after the two mirros: P3, P4, and P5.
