DETERMINATION OF FOILS THICKNESS BY ALPHA SPECTROSCOPY

Abstract

 Nowadays, in both industry and scientific research, there has been a demand for determination of matters thickness. In this article we will bring out two methods which are very simple, fast, effective and low-cost in getting exactly thickness of thin foils (µm). Both two these methods are based on energy loss of alpha particle when it passed through foil and then detected by high energy resolution alpha spectroscopy.
