0028 // Process describing a radiator of X-ray transition radiation.
0029 // Thicknesses of plates and gas gaps are fixed.
0030 // We suppose that:
0031 // formation zone ~ mean thickness << absorption length
0032 // for each material and in the range 1-100 keV. This allows us to simplify
0033 // interference effects in radiator stack (GetStackFactor method).
