FIELD: medicine; radiation therapy.
SUBSTANCE: method of converting a beam of monoenergetic protons into a beam of complex spectrum protons during radiation therapy operations comprises the following stages, on which monoenergetic protons are passed through a shaping plate with thickness sufficient to reduce the energy of protons to the maximum energy of the spectrum, behind the shaping plate, filters-absorbers of protons of different thickness, which are fixed on the disk, are installed, the disk shaft is installed parallel to the beam axis at a distance sufficient for the beam passage through the absorbent filters.
EFFECT: conversion of a beam of monoenergetic protons into a beam of complex spectrum protons during radiation therapy operations.
