The Marshall Grazing Incidence Spectrometer {\it MaGIXS} is a sounding rocketexperiment that will observe the soft X-ray spectrum of the Sun from 24 - 6.0\AA\ (0.5 - 2.0 keV) and is scheduled for launch in 2021. Component andinstrument level calibrations for the {\it MaGIXS} instrument are carried outusing the X-ray and Cryogenic Facility (XRCF) at NASA Marshall Space FlightCenter. In this paper, we present the calibration of the incident X-ray fluxfrom the electron impact source with different targets at the XRCF using a CCDcamera; the photon flux at the CCD was low enough to enable its use as a"photon counter" i.e. the ability to identify individual photon hits andcalculate their energy. The goal of this paper is two-fold: 1) to confirm thatthe flux measured by the XRCF beam normalization detectors is consistent withthe values reported in the literature and therefore reliable for {\it MaGIXS}calibration and 2) to develop a method of counting photons in CCD images thatbest captures their number and energy
