/// \brief Definition of the XTRTransparentRegRadModel class

// 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:
//
// 05.04.05 V. Grichine, first version
//
