Résumé

A proton recoil spectrometer has been constructed and used to obtain energy spectra of neutrons emitted from targets bombarded by 160- and 450-MeV protons. The instrument employs a polyethylene radiator as the source of the recoil protons and measures the energy of the protons from the pulse height obtained when the proton passes through a thin NaI(Tl) crystal. The paper discusses the details of constructing the spectrometer and the circuitry used during operation. A Monte Carlo program for calculating the efficiency and resolution of the spectrometer is described. The effect of the Landau spread in the energy deposited in the NaI(Tl) energy detector is included in the resolution calculation. Typical energy spectra for secondary neutrons and protons are presented and the unfolding program used to compensate for the skewed energy resolution function of the spectrometer is discussed.
