A facility for studying (n,p) reactions at neutron kinetic energies of 140 ≲ Tn ≲ 300 MeV has been constructed by using the existing Large Acceptance Spectrometer at the Research Center for Nuclear Physics, Osaka University. A neutron beam produced by the 7Li(p,n) reaction hits the (n,p) targets located in a segmented target system, which allows one to use a relatively thick target in total (∼ 0.5 g / cm2) with a moderate energy resolution of ∼ 1 MeV. The facility enables one to obtain spectra at 300 MeV up to an excitation energy of 70 MeV with a single setting of the spectrometer. This (n,p) facility has a large effective solid angle of 11 msr for an effective target size of 30W × 20H mm2.
