Claim of US Patent No. 10,798,812

1. A particle accelerator comprising:a pair of magnetic poles disposed to face each other;
a coil which surrounds each of the magnetic poles and generates a first magnetic flux density directing from the magnetic pole on one side to the magnetic pole on the other side;
a foil stripper provided on a circling orbit of charged particles to strip off electrons from the charged particles; and
a magnetic flux density adjustment unit which generates a second magnetic flux density directing in an opposite direction to a direction of the first magnetic flux density,
wherein the magnetic flux density adjustment unit makes an absolute value of magnetic flux density at a position of the foil stripper when viewed in a plan view smaller than an absolute value of the first magnetic flux density.
