The present invention relates to a beam
distribution system and
irradiation terminal based on multi-angle
irradiation, wherein the beam
distribution system comprises: a
fixed beam line and a rotating beam line, both of which are fixed on a rotating frame; the rotating beam line comprises a rotating section single
dipole magnet, a horizontal beam line and a plurality of inclined beam lines at a certain angle to the ground, the horizontal beam line and the plurality of inclined beam lines are branches of the
fixed beam line, the beam pre-separated by the rotating section single
dipole magnet enters the horizontal beam line or the plurality of inclined beam lines, and the rotating section single
dipole magnet is electrically connected to a variable pre-excitation full
energy storage power supply. The
system adopts a one-to-many solution, that is, only one beam line is required for one
irradiation direction, and a plurality of beam distribution lines are used to form multi-angle irradiation, and the
beam splitting direction is controlled by a single
dipole magnet. At the same time, a rotation point is designed in front of the
dipole magnet, and the beam line is rotated to form a multi-terminal
layout without adding other beam lines, and finally a
layout of multi-irradiation terminals and single-terminal multi-angle irradiation is realized.
