Title: PARTICLE ACCELERATOR
Abstract:
This particle accelerator is provided with: a pair of magnetic poles that are arranged oppositely to each other; a coil that surrounds each of the magnetic poles and generates a first magnetic flux density oriented from one magnetic pole toward the other magnetic pole; a foil stripper that is provided on the circulating orbit of charged particles and strips off electrons from the charged particles; and a magnetic flux density adjustment unit that generates a second magnetic flux density oriented in a direction reverse to that of the first magnetic flux density, wherein the magnetic flux density adjustment unit sets the absolute value of magnetic flux density at the position of the foil stripper in a plan view to be less than the absolute value of the first magnetic flux density.
