// 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
|
