A SYSTEM OF LARGE LIQUID SCINTILLATION COUNTERS USED WITH A SIMPLIFIED NEUTRON-GAMMA DISCRIMINATION TECHNIQUE

A system of NE 213 liquid scintillator neutron counters working with a straightforward neutron-gamma discrimination technique and a digitized data output is described. The apparatus was built up using only standard electronics, and has been working at CERN in recent muon capture experiments. The performances of the neutron counters are reported with particular reference to the neutron-gamma discrimination features and to the energy resolution. The calculation of the efficiency of the described system is also discussed. © 1969.
