An Isotropic Source of Neutrons ID: 2014-076

A revolutionary neutron source offering isotropic emission for precise calibration of neutron detectors.

Technology Overview

This invention presents a novel approach to generating a spherical neutron source, designed to emit neutrons isotropically, thereby providing an even neutron flux in all directions. This technology is particularly aimed at calibrating neutron detectors within the MeV energy range, addressing the limitations of traditional ionization fission chambers that suffer from non-isotropic emission. The core innovation involves a spontaneously fissioning isotope mixed with a scintillating material that detects fission events, with emitted light captured by a photomultiplier tube for accurate measurement.

Key Advantages

• Ensures equal neutron flux in all directions, improving calibration accuracy
• Addresses the limitations of non-isotropic emission found in traditional fission chambers
• Utilizes a spontaneously fissioning isotope, enhancing the efficiency of neutron generation
• Incorporates scintillating material for effective detection of fission events

Problems Addressed

• Non-isotropic neutron emission in current calibration technologies
• Inaccuracies in neutron detector calibration within the Me
• V energy range

Market Applications

• Calibration of neutron detectors in nuclear physics research
• Enhancement of nuclear safety and security measures through improved detection technologies
• Potential applications in medical physics, particularly in treatments and diagnostics involving neutron radiation
