The Kansai BNCT Medical Center has a cyclotron based epithermal neutron source for clinical Boron Neutron Capture Therapy. system accelerates proton to an energy of 30 MeV which strikes beryllium target producing fast neutrons are moderated down use. While studies in the past have shown be highly effective malignant melanoma skin, apply superficial lesions using this it is necessary shift therm...

Boron Neutron Capture Therapy (BNCT) is a relatively safer technology for killing cancer cells, one of which the Glioblastoma multiforme. One main components BNCT equipment collimator functions as an exit point epithermal neutron particles that hit cells. In addition to experimental method, research can be carried out by modeling, including using MCNPX software based on Monte Carlo Method. This...

The advance of the cosmic ray neutron (CRN) sensing method for estimating field scale soil moisture relied largely on simulations footprint properties epithermal neutrons (∼0.5 eV–100 keV). Commercially available CRN probes are usually additionally equipped with a thermal (<0.5 eV) detector. potential these measurements is rarely explored because relevant features neutrons, such as and sensitiv...

An accelerator-based BNCT (Boron Neutron Capture Therapy) facility is being constructed at the Ibaraki Neutron Medical Research Center. It consists of a proton linac of 80kW beam power with 8 MeV energy, a beryllium target, and a moderator system to provide an epithermal neutron flux sufficient for patient treatment. The technology choices for this present system were driven by the need to hous...

For accuracy improvement of neutron activation analysis and capture cross sections, bias effects are investigated on g- s-factors in the Westcott convention. As origins biases, a joining function shape, temperature, sample temperature have been investigated. Biases quantitatively deduced for two 1/v isotopes (197Au, 59Co) six non-1/v (241Am, 151Eu, 103Rh, 115In, 177Hf, 226Ra). The s-factor calc...
