Performance evaluation of the source description of the THOR BNCT epithermal neutron beam. | LitMetric

AI Article Synopsis

  • This paper evaluates the performance of the THOR BNCT beam source description using various measurement techniques across different phantoms.
  • The methods used included measuring absolute reaction rates with triple activation foils, neutron and gamma-ray dose rates using ionization chambers, and relative reaction rate distributions from indirect neutron radiography.
  • Results indicated that the THOR-Y09 source description is reliable for both neutron and gamma-ray components, outperforming the other tested sources (RSSA and THOR-50C).

Article Abstract

This paper aims to evaluate the performance of the source description of the THOR BNCT beam via different measurement techniques in different phantoms. The measurement included (1) the absolute reaction rate measurement of a set of triple activation foils, (2) the neutron and gamma-ray dose rates measured using the paired ionization chamber method, and (3) the relative reaction rate distributions obtained using the indirect neutron radiography. Three source descriptions, THOR-Y09, surface source file RSSA, and THOR-50C, were tested. The comparison results concluded that THOR-Y09 is a well-tested source description not only for neutron components, but also for gamma-ray component.
