This study explores a novel three-step laser-induced nuclear fission process to enhance neutron and fast ion production. The method utilizes laser-target interactions to initiate thorium-232 fission, producing uranium-233 and amplifying laser pulses.

Area of Science:

  • Nuclear Physics and Engineering
  • Laser-Plasma Interactions
  • Nuclear Energy

Background:

  • Research investigates induced nuclear fission of high-Z elements via electromagnetic interactions (photofission, electron fission, neutron fission).
  • Fast ions, neutrons, and fission fragments from these interactions show potential for pumping laser media and energy production via the thorium-232-uranium-233 cycle.

Purpose of the Study:

  • To investigate a novel three-step experimental scheme aimed at enhancing the production of neutrons and fast ions.
  • To improve the efficiency of the thorium-232-uranium-233 nuclear fission cycle for energy production and laser pumping.

Main Methods:

  • High-intensity laser beam interaction with solid or gas targets to produce high-energy particles and photons.
  • Utilizing produced particles and photons to trigger nuclear reactions, specifically initiating photoneutron production.
