Csl(Tl) scintillator telescope measurement of charged particles extracted from the KCCH MC-50 cyclotron

Abstract

A telescope was made with a 150-mu m-thick silicon surface barrier detector (Delta E) and a cylindrical CsI(Tl) scintillator (E). A 50-MeV proton beam from the MC-50 cyclotron was incident on a Ag-nat foil, and outgoing particles were measured with the telescope. Particle identification was performed with the telescope, and particles were identified to be protons, deuterons, and tritons with the help of the range-energy relation. The differential cross sections for the Ag-nat(p,p) reaction leading to the groundstate of Ag-nat were measured and compared with the result of an optical model calculation. This result showed some possibility for charged particle experiments using the cyclotron at the Korea Cancer Center Hospital.
