Installation for investigation of cumulative photoproduction of particles on nuclei (''Deuteron'')

The description and experimental characteristics of a two-arm installation for inVestigation of nuclear photofragmentation is given. One of the arms is a scintillation-range telescope which allows to identify simultaneously protons and π mesons in the energy range 80-300 MeV and 45-160 MeV, respectively for detection angles 20 deg-160 deg. Absolute energy are 15-6 MeV and 6-3.5 MeV both for protons and π mesons, respectively. A second arm is a magnetic spectrometer with use of the time-of-flight measurement technique. The spectrometer permits to identify reliably πsup(+-) mesons and protons with momenta 0.18-1.5 GeV/s and 0.5-1.5 GeV/s, respectively for detection angles 20 deg -120 deg. The momentum resolution is approximately 13% at a solid angle 1.25 msr
