METHOD OF OBTAINING AN IMAGE OF AN OBJECT OF STUDY AT THE GAS-DYNAMIC PROCESS STAGE OF INTEREST USING A PROTON ACCELERATOR Russian patent published in 2020 - IPC G01N23/04 

FIELD: physics.

SUBSTANCE: invention can be used to obtain an image of an object of study at a gas-dynamic process stage using a proton accelerator. Essence of the invention consists in the fact that performing the dynamic loading of the research object by blasting the explosive substance when exposed to the proton accelerator, for this purpose, the blasting apparatus is triggered with start-up of the proton accelerator by means of a delay line and the onset of the gas-dynamic process of interest by means of a sensor is monitored. Delay line used is a generator of delayed pulses in the trigger circuit of a blasting apparatus, and as a sensor - a sensor which interacts with proton bunches, delay time of starting the blasting apparatus T_dpg relative to the time of supply of electric pulse from the control panel of the proton accelerator is introduced into the generator of delayed pulses, which advances the arrival time of the first proton bunk to the test object for a time T_to, wherein the delay time T_dpg is determined in stages, first evaluating this value from the ratio T_dpg^'=T_to-T_est, where T_est is the design time from the moment of receipt of the blasting pulse on the explosive substance before the passing of the proton bunches through the object of investigation at the dynamic loading stage of interest, and introducing it into the delayed pulse generator, further varying the estimated value T_dpg^', performing control starts of the proton accelerator together with the blasting apparatus without dynamic loading of the survey object, at that, the oscilloscope determines the moments of arrival of electric pulses from the control panel of the proton accelerator t₁, from the blasting apparatus t₂ and from the sensor interacting with the proton bunches t₃, selecting the value t₂at which the following ratio is satisfied: T_est=t₃-t_sp-(t₂-t_eu+t_em), where t_sp, t_eu, t_em are the line lengths in the sensor circuits interacting with the proton bunions, starting the blasting apparatus and the blasting line, respectively, with final value T_dpg, which corresponds to selected value t₂, dynamic loading of research object is carried out and image of object of investigation is obtained at the stage of gas-dynamic process of interest.

EFFECT: high quality and number of images when using a proton accelerator.
