This study introduces a novel inverse method for the Boltzmann transport equation using angle-independent flux measurements to determine shield interface locations. The technique shows promise for applications in radiation shielding and inverse problem analysis.

Area of Science:

  • Nuclear Engineering
  • Computational Physics

Background:

  • Adjoint and forward functions are established for gradient computation in inverse problems across various scientific fields.
  • Their application to inverse solutions of the Boltzmann transport equation is infrequent, with prior methods requiring angle-dependent flux measurements.

Purpose of the Study:

  • To develop a novel inverse method for the Boltzmann transport equation.
  • To enable the determination of interface locations in multilayer shields using only angle-independent flux measurements.
  • To simplify inverse solutions by avoiding the need for angle-dependent data.

Main Methods:

  • The study employs adjoint functions in conjunction with forward functions for gradient computation.
  • A simplified Boltzmann transport equation, excluding scattering, is utilized.
