Neutron response functions of a silicon sensor, which is applied to a new real-time personal albedo neutron dosemeter, have been simulated for low energy neutrons from 0.01 eV to 10 keV using the Monte Carlo technique. The angular neutron response fu

We previously reported that swallowing in the bridge position (bridge swallowing) increased distal esophageal contractions and lower esophageal sphincter pressure against gravity. Moreover, bridge swallowing had the potential to strengthen esophageal

We have developed a new real-time neutron detector, which is able to measure a direct neutron beam of boron neutron capture therapy. The detector consists of both a 40- μ m-thick pn diode and around 0.09- μ m-thick LiF neutron converter. Experiment

Response functions of a 60-μm thick neutron silicon sensor to 8-MeV neutrons were obtained experimentally and simulated using a Monte Carlo code. The simulation reproduced the experimental results well, however it was found that the discrepancy was
