Abstract

A spectrometer for the detection of neutral pions in nuclear physics research was designed, constructed, and tested at the Los Alamos Meson Physics Facility. It is capable of detecting neutral pions with high efficiency, and with a fwhm energy resolution of 2 MeV with a typical acceptance of 1 msr. In the first experiment in which the spectrometer was used, its performance was evaluated, and nuclear physics research, based on the detection of neutral pions, was performed.
