Design and making methods of a neutrons generating target are described. In some embodiments, a surface of a target substrate can be modified to form one or more surface features. In some embodiments, a neutron source layer can be disposed on the surface of the target substrate. In some embodiments, the neutron source layer and the target substrate can be heated to an elevated temperature to form a bond between the two. In some embodiments, the surface modification of the target substrate can reduce blistering and material exfoliation in the target. The target can be used in boron neutron capture therapy.

Abrégé

The present disclosures relates to an ion beam assembly where a relatively small deflection angle (approximately 15° from the center of the beam line) is used in conjunction with two beam dumps located on either side of the beam. In some embodiments, the combination of the two beam dumps and the magnet assembly can provide an ion beam filter. In some embodiments, the resulting system provides a smaller, safer and more reliable ion beam. In some embodiments, the ion beam can be a proton beam.
