Development of a real-time neutron beam detector for boron neutron capture therapy using a thin silicon sensor

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-mu m-thick pn diode and around 0.09-mu m-thick LiF neutron converter. Experimental results indicate that this neutron detector can measure neutron flux up to 1 x 10(9) (cm(-2) s(-1)), separately from gamma rays around 500 mGy/h. The measured depth distribution of neutron flux in an acrylic block is in agreement with the activation results of gold.

Automated summary

The team has developed a new real-time neutron detector that can accurately measure the neutron beam in boron neutron capture therapy, showing good performance in experimental results.
