00032 // Process describing a radiator of X-ray transition radiation.  
00033 // Thicknesses of plates and gas gaps are fixed.
00034 // We suppose that:
00035 // formation zone ~ mean thickness << absorption length
00036 // for each material and in the range 1-100 keV. This allows us to simplify
00037 // interference effects in radiator stack (GetStackFactor method).
