Key Findings from the Study

Researchers developed a two-pronged approach to analyze neutron field behavior in large-scale fusion reactors:

• Neutron Activation Methods: Used to measure variations in neutron anisotropy and yield distribution.
• Time-of-Flight Spectral Analysis: Helps determine neutron spectra distortions using advanced MCNP (Monte Carlo N-Particle) simulations.

By leveraging Dense Plasma Focus (DPF) technology, which generates high-intensity quasi-monoenergetic neutron pulses, scientists could evaluate the impact of reactor surroundings on neutron field characteristics.

Importance of Accurate Neutron Field Characterization

Ensuring precise neutron field mapping is critical for:

• Optimizing reactor shielding designs
• Enhancing diagnostic accuracy
• Reducing material degradation in fusion environments

The International Thermonuclear Experimental Reactor (ITER) and Wendelstein 7-X Stellarator (W7X) are among the key projects that could benefit from this method.

Integration with External Medical & Scientific References

The International Atomic Energy Agency (IAEA) emphasizes the significance of neutron diagnostics in fusion research. By applying methodologies such as neutron activation and spectral analysis, fusion research facilities can enhance reactor performance and minimize radiation exposure risks.
