Requalification and Experimental Validation of the Epithermal Neutron Beam Facility for Radiotherapy Research at Washington State University

摘要

Approximately ten years ago the Idaho National Laboratory (INL) and Washington State University (WSU) completed the construction of a new epithermal-neutron beam for collaborative preclinical Neutron Capture Therapy (NCT) research at the WSU TRIGA™ research reactor facility1. Since then the reactor core has been reconfigured to use Low-Enriched Uranium (LEU) fuel, and significant interest has emerged recently with respect to potential use of the facility for actual clinical (human) trials as well as for preclinical work. Both of these developments have necessitated a complete experimental revalidation of the neutronic performance of the beamline over the past 18 months. This article summarizes the results of the physics requalification effort.
