3. Способ измерения флюенса и энергетического спектра мощных импульсных протонных пучков, включающий калибровку методом калориметрических измерений флюенса тепловой энергии Q тонкой металлической мишенью, отличающийся тем, что в качестве измеряемой величины выбирают временной интервал ΔtC-H между моментами появления сигналов от водородной и углеродной компонент абляционной плазмы, образованной при взаимодействии пучка протонов со слоем поверхностных углеводородных загрязнений обрабатываемой мишени, а калибровочную зависимость для флюенса протонов F = f(ΔtC-H) находят в процессе калориметрических измерений Q = f(ΔtC-H) по выражению F = Q/k, k = ∫f(E)dE/∫dE - постоянный коэффициент, учитывающий энергетический спектр протонов.2. The method according to claim 1, characterized in that the calibration dependence for the proton fluence F = f (Δt CH ) is found in the process of radioactive measurements of partial fluences (energy spectrum) of protons by activation of targets containing Mg, N and Si, according to nuclear resonance reactions
3. A method for measuring the fluence and energy spectrum of high-power pulsed proton beams, including calibration by the method of calorimetric measurements of the fluence of thermal energy Q with a thin metal target, characterized in that the time interval Δt CH between the moments of appearance of signals from the hydrogen and carbon components of the ablation plasma is selected as the measured quantity formed by the interaction of the proton beam with a layer of surface hydrocarbon contamination of the target being processed, and the calibration dependence for lyuensa protons F = f (Δt CH) are in the process of calorimetric measurements Q = f (Δt CH) from the expression F = Q / k, k = ∫f (E) dE / ∫dE - constant coefficient reflecting the energy spectrum of protons.
