// 
// Process describing a radiator of X-ray transition radiation.  
// Thicknesses of plates and gas gaps are fixed.
// We suppose that:
// formation zone ~ mean thickness << absorption length
// for each material and in the range 1-100 keV. This allows us to simplify
// interference effects in radiator stack (GetStackFactor method).
// 
// 
// History:
// 16.01.02 V. Grichine, first version
