The paper demonstrates that temporal behavior of proton components of intense pulsed ion beams accelerated to average energy of up to 200 keV with number of 1015 per shot can be reliably evaluated with use of prompt -spectrometry. The ion shots are dumped onto a pyrolytic h-BN plate in which a 5 mm diameter hole is provided to enable simultaneous time-of-flight measurement of the ion species with a Biased Ion Collector. The proton energy and number are determined by simultaneous control of signals from two organic scintillators shielded with lead layers of 2 and 3 cm to evaluate contributions of the nuclear reactions 10B(p, alpha, gamma)7Be and 11B(p, gamma)12C via measurement of yields of prompt gamma-rays with energies of 429 and 4439 keV, respectively.
