CCM

An artificial channel-cut monochromator (CCM) is available for use on the XCS instrument. The system design is adopted from the work of Narayanan et al. (J. Synchrotron Rad. (2008) 15, 12-18).

This system currently uses Si (111) crystals and thus has a energy resolution of 1.4x10^-4 (ΔE/E). The mechanics of this system are appropriate for scanning measurements such as those required for various X-ray spectroscopies. The CCM may be retracted when not needed. Please note that the CCM displaces the beam +5.3 mm in the vertical plane at 6.5keV.

The lower energy bound is ~5 keV and the higher is above 25 keV.
