Abstract
A cancer treatment apparatus has a neutron source generating neutrons exiting through a surface of a moderator block and an elongated beam-shaping apparatus (BSA) having a length and a circular cross section of a diameter less than the length, the BSA joined at one end to and projecting orthogonally from the surface of the moderator block of the neutron source, the BSA having a conically shaped element at an end away from the moderator block, the conically shaped element declining in diameter in a direction away from the moderator block. Neutrons produced by the neutron source enter the BSA at the surface of the moderator block, travel the length of the BSA, and exit the BSA through an aperture at the end of the BSA away from the moderator block.
