Characteristics of Si-PIN diode X-ray detector with DSP electronics

In the present work, the studies to investigate the features of PIN diodes detector coupled with a digital processor have been extended. At low energies, backscattered Compton peaks are close in energy to photo peak of the gamma of interest. Thus the backscattered peaks pose a serious problem in the analysis of spectra of low energy gamma rays. It has been initiated some measurements to quantitatively estimate the same as function of energy and Z of the scatterer. Recently there has been application of backscattering in high-resolution gamma backscatter imaging for technical applications
