Identification of Charged Particles by Multiplying Circuit

Abstract

A pulse multiplying circuit for charged particle identification according to (E+E₀+k·dE/dx)×dE/dx E₀, k : const was made, in which a squaring circuit using eighteen diodes was devised. The E and dE/dx pulses, due to the incidence of charged particles, were given by a semiconductor detector and a proportional counter of gas flow type, respectively. The charged particles of low energies from D+d, T+d, Li+d and Be+d nuclear reactions were sorted by this circuit. A test for carbon ions was also done. The apparent separation ratios were as follows : ρ : τ : α : C≈1 : 2 : 9 : 60
