| Summary: | Title screen A two-channel γ-spectrometer with time resolution of 2.5 ns enables a prompt control of number and energy of collectively accelerated protons in their separate bunches dumped into a sustainable and refractory B4C target. The proton energy and number is determined within the range of 460 to 1600 keV and 1012-4⋅1014 per pulse, respectively, by separate measurements of yields of prompt γ-rays with energies of 429 and 2366 keV and higher, induced in the B4C targets via the nuclear reactions 10B(p, α γ)7Be, 11B(p, γ)12C and 12C(p, γ)13N, respectively. The simultaneous control of signals from two organic scintillators shielded with lead layers of 1 and 7 cm is used to reliably separate contributions of the analytical reactions. The radioactivity of 7Be and 13N radionuclides produced in the reactions is measured with a conventional HP Ge detector to calibrate the prompt technique.
