Abstract：
This paper develops a method of Vector Projection (VP) , which is based on investigations and a mathematical abstraction of many methods of Pulse Shape Discrimination (PSD) used in particle identification. VP is a universal method and its optimum parameter selection is discussed in detail. Optimized PSD effect by using VP with appropriate parameters is verified utilizing the data obtained from the FADC measurement system.
