Description
A scintillator detector model taking photoabsorption efficiency into account. As such it consitututes a more physical version of the PSD_monitor. Only direct absorption is taken into account.
Example: Detector_pn(restore_xray=restore_flag,filename=”detector_Si”, material_datafile=”Si.txt”, xwidth=1e-2, yheight=1e-2,zdepth=1e-5)
