In spectroscopy, spectral flux density is the quantity that describes the rate at which energy is transferred by electromagnetic radiation through a real or virtual surface, per unit surface area and per unit wavelength (or, equivalently, per unit frequency) It is a radiometric rather than a photometric measure In SI units it is measured in W m −3, although it can be more practical toXRayBob Minification, Flux, & Brightness Gain Math Examples Watch later Share Copy link Info Shopping Tap to unmute If playback doesn't begin shortly, try restarting your device You'reIn order to make it easier for the user to calculate flux on the xray beam lines the following graphs are presented The first is a plot of flux vs energy for several of the insertion device beam lines at SSRL and, for comparison, the flux from BL 15, the original "EXAFS I"

X-ray flux calculation-We present a very simple formula for calculating the total number of photons of an xray beam after being monochromatized by a double crystal monochromator This is a typical case for most synchrotron radiation beamlines The derivation of the formula and its numerical benchmarking by raytracing simulations are also presentedThe calculation of the net radiation flux was primarily influenced by the calculation of the global solar radiation flux under cloudless conditions, but under overcast conditions it was largely influenced by the calculation of the net longwave radiation flux The net radiation flux could be predicted successfully only when locally determined
