Simulation Research of Charged Particle Discrimination Methods

Article Preview

Abstract:

A simple model was used to simulate the current pulse induced by charged particles with Si detector. With simulated current shapes of three element groups, H/D/T (6MeV), He-3/He-4 (15MeV) and Li-6/Li-7 (35MeV), three methods of pulse shape analysis (PSA), i.e. the m2-m3 method, the integration method and the second moment method, were compared and analyzed. Their discrimination performance and noise resisting property are investigated. The results show that the charge integration method and the m2-m3 method both have good discrimination performance and noise resisting property. While neither the discrimination performance nor the noise resisting property of the second moment method is satisfactory.
