A two-dimensional position sensitive charged-particle detector for the magnetic spectrograph “Big Karl” of the Jülich Cyclotron “Jülich”

Abstract

A two-dimensional position sensitive detector with an area of 300 mm × 40 mm and a charged-particle spatial resolution of ΔX = ΔY ⩽ 0.5 mm is described. Some test results point out the detector properties. Results of the experiments 102Ru(d,p) 103Ru and 208Pb(p,p′) 208Pb done at 45 MeV incident particle energy using the magnetic spectrograph BIG KARL are shown with sections of the proton spectra.
