A Range telescope technique for particle discrimination and energy reconstruction

We present an analysis technique (“range method”) that optimizes particle discrimination and enables energy reconstruction using a sampling detector. The method is a powerful extension of the well known d E d x - E technique in which the energy loss rate measured by several scintillator layers is fitted on the theoretical energy-range curves. The general features of the method will be discussed and its application to nuclear physics investigations at intermediate energies with the DAPHNE detector. Momentum reconstruction for protons with a resolution of ΔP P = 2.5−10% (FWHM) in the range P = 300–900 MeV/ c has been obtained.
