An Experimental Method to Study the Structural Differences of Surface Barrier Detectors by Studying the Energy Distribution of Noise

Mai Razzok, Abdullah Rastanawi


In this paper, we studied two surface barrier detectors, which are different in polarity and contacts. Where in the first detector, the negative pole is made of gold and the positive one is made of aluminum. While in the second detector, the situation is reversed. This study showed that the design of the first detector is better than the second one because it emitted less noise. This is because ionization potential of gold is smaller than that of aluminum.

Keywords: surface barrier detectors, distribution of noise.
