摘要：

A two-channel y-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 10(12)-4.10(14) per pulse, respectively, by separate measurements of yields of prompt gamma-rays with energies of 429 and 2366 keV and higher, induced in the B4C targets via the nuclear reactions B-10(p, alpha gamma)Be-7, B-11(p, gamma)C-12 and C-12(p, gamma)N-13, 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 Be-7 and N-13 radionuclides produced in the reactions is measured with a conventional HP Ge detector to calibrate the prompt technique.
