+// Very rough model describing a radiator of X-ray transition radiation.  
+// Thicknesses of plates and gas gaps are exponentially distributed.
+// We suppose that:
+// formation zone << mean thickness << absorption length
+// for each material and in the range 1-100 keV. This allows us to simplify
+// essentially interference effects in radiator stack (GetStackFactor method).
+// The price is decreasing of X-ray TR photon yield. 
+// 
+// History:
+// 23.01.00 V. Grichine first version based on ExN05PiModel class
+// 08.02.00 V. Grichine, DoIt was placed in base class
