This paper presents X-ray spectra of channeling radiation expected at the FAST (Fermi Accelerator Science andTechnology) facility in Fermilab. Our purpose is to produce high brightness quasi-monochromatic X-rays in anenergy range from 40 keV to 110 keV. We will use a diamond crystal and low emittance electrons with an energyof around 43 MeV. The quality of emitted X-rays depends on parameters of the electron beam at the crystal.We present simulations of the beam optics for high brightness and high yield operations for a range of bunchcharges. We estimate the X-ray spectra including bremsstrahlung background. We discuss how the electron beamdistributions after the diamond crystal are affected by channeling. We discuss an X-ray detector system to avoidpile-up effects during high charge operations
