0033 // Process describing a radiator of X-ray transition radiation.
0034 // Thicknesses of plates and gas gaps are fixed.
0035 // We suppose that:
0036 // formation zone ~ mean thickness << absorption length
0037 // for each material and in the range 1-100 keV. This allows us to simplify
0038 // interference effects in radiator stack (GetStackFactor method).
