The variation in the power radiated by electrons in a circular orbit through an aperture was investigated numerically as a function of the distance along a tangent to the orbital ring. For electron energies above 0.1 GeV, the power radiated into a rectangular aperture, placed at a distance greater than the radius of curvature of the orbit, does not differ by more than 4 parts in 106 from the power radiated into a similarly sized rectangular aperture (subtending the same solid angle) placed at a large distance from the orbital ring. Our conclusion is that, within the limits considered, synchrotron radiation can be calculated accurately for practical radiometric calibrations.

  10. Reduced parameters are extremely useful for synchrotron radiation. By using the reduced parameter λ¯ = λ/λc, and Ψ¯= , one can write scaling relationships of the form IE(λ, Ψ) = 2I(λ¯). Thus, if one table of the universal intensity function (λ¯,Ψ¯) is available for a large range of λ¯ and Ψ¯, one can scale the results and produce a table for the intensity function IE (λ, Ψ) for any electron energy (see Refs. 8 and 9).
