Researchers developed a method to tag fast neutrons from an Americium-241/Beryllium (Am/Be) source. This creates an energy-tagged neutron beam up to 7 MeV, matching theoretical predictions.

Area of Science:

  • Nuclear physics
  • Radiation detection

Background:

  • Fast neutron beams are crucial for various applications in science and industry.
  • Characterizing neutron energy is essential for accurate experimental results.

Purpose of the Study:

  • To develop and demonstrate a technique for producing an energy-tagged fast neutron beam.
  • To characterize the energy spectrum of the generated neutron beam.

Main Methods:

  • Utilized shielding, coincidence detection, and time-of-flight (TOF) measurements.
  • Employed an Americium-241/Beryllium (Am/Be) neutron source.
  • Tagged emitted fast neutrons up to 7 MeV.

Main Results:

  • Successfully generated a continuous, polychromatic, energy-tagged neutron beam.
