METHOD OF IMAGING HIGH-SPEED PROCESS USING PROTON RADIATION Russian patent published in 2016 - IPC G01N23/00 

FIELD: physics.

SUBSTANCE: method includes inputting a proton beam into at least one magneto-optical channel; changing the width of the proton beam by different values, which is carried out consecutively in the same magneto-optical channel; to this end, either after part of proton bunches passes through a scatterer, removing the scatterer or changing the thickness, and then passing the remaining part of proton bunches, or offsetting consecutive proton bunches relative to each other using magnetic lenses, and, using a different-thickness scatterer, passing the offset proton bunches through the region of the scatterer with a different thickness; after passing through the scatterer, using a system of matching magnetic lenses, forming a proton beam with parameters which correspond to parameters of the investigation region and the next magneto-optical proton imaging system; and illuminating the investigation region by consecutively passing proton bunches of different width; using multiple magneto-optical channels illumination of the investigation region is carried out at different angles, after which the proton beam that has passed through is directed to the magneto-optical proton imaging system consisting of at least two aperture-different lens systems, the aperture of each set corresponding to the proton beam of a defined width; both lens sets of the shadow proton imaging system are arranged in series in one magneto-optical channel.

EFFECT: obtaining a high-quality image of the investigation region.
