Abstract
The beam-shaping assembly for boron neutron capture therapies with a compact accelerator-driven subcritical neutron multiplier was designed so that an epithermal neutron flux of 1.9Ã109Â cmâ2Â sâ1 at the treatment position was generated by 5Â MeV protons in a beam current of 2Â mA. Changes in the atomic density of 135Xe in the nuclear fuel due to the operation of the beam-shaping assembly were estimated. The criticality safety of the beam-shaping assembly in terms of Xe poisoning is discussed.
