Abstract
Generally, a thin Be (1-2 mil) is used as a window for Si (Li) detector used for X-ray spectroscopy. When Be undergoes wear and tear and ruptures it can be replaced by an aluminium window. In a case we have replaced a broken Be window with an Al window of thickness 450 μ and 15 mm diameter and have seen an excellent performance of the detector. Samples of biological significance (bacterial cells) and foils of double layer thickness were analyzed using the Am241 radioisotope source as excitation source and Al window detector and the elements were detected and seen well separated.
