A Formation of Ion Intensity Distributions on a Target Appropriate for a Neutron Source for Boron Neutron Capture Therapy

Abstract

This paper proposes a new method of scanning beams from several radio-frequency quadrupole (RFQ) accelerators on a target, and gathering them into a bundle of ion beams on the target which is prepared for a neutron source of boron neutron capture therapy(BNCT). The scanning apparatus is composed of a solenoid coil and wobbling magnets. The method will be found to produce various forms of ion intensity distributions on the target, and as a result, to provide the neutron source with favorite neutron flux distributions for BNCT.
