Abstract

A fast and effective algorithm for electromagnetic and hadronic shower separation has been developed for the digital sampling calorimeter of the CHARM II experiment. It is based on a generalization of the minimal spanning tree concept and can be easily applied to other existing calorimeters. In this particular application, which requires the highest efficiency for retaining electromagnetic showers, one gets, for 99% efficiency, a rejection factor of the order of 100 for hadronic showers.

Abstract

We report on experimental results obtained with the neutrino target calorimeter of the CHARM II detector. The experiment is being performed at CERN and its aim is to measure sin2θw, the electroweak mixing parameter, via the study of neutrino-electron scattering. The detector, installed on the SPS neutrino wide-band beam line, consists of a glass calorimeter instrumented with plastic streamer tubes and scintillation counters, and of a muon spectrometer. The performance of the calorimeter has been explored during a test run with electron and pion beams. Results concerning the detector response, the energy and angular resolution, and the e π separation are presented here.
