Monte Carlo Methods for Particle Transport Problems


A. Highly Recommended

Forrest Brown, "Monte Carlo Techniques for Nuclear Systems - Theory Lectures", LA-UR-16-29043, (2016).
Lecture notes on theory for the Monte Carlo class that is taught to senior undergraduate & graduate students in the Nuclear Engineering Department at the University of New Mexico. For undergraduate students, this 1-semester class is required for graduation. There are 600 slides covering all of the basics for Monte Carlo particle transport & some advanced material. These notes are a significantly expanded & improved version of LA-UR-05-4983. Portions of these notes are also used in the MCNP Criticality Class given at LANL.

Forrest Brown, "Advanced Computational Methods for Monte Carlo Calculations", LA-UR-18-20247, (2018).
Lecture notes for an advanced Monte Carlo class for graduate students at the University of New Mexico. Focused on transport theory, random sampling, & coding issues. The target audience is (1) graduate students who may need to write their own MC codes as part of their research, & (2) professionals who need to know the underlying theory & sampling methods that arise in mature, production-level codes. There are 500 slides presenting material that is advanced, detailed, & specific, and not found in textbooks, reports, or other classes.

Forrest Brown, “Fundamentals of Monte Carlo Particle Transport”, LA-UR-05-4983, (2005).
Lecture notes for a 10 week class on Monte Carlo methods for particle transport calculations:
Solving particle transport problems with the Monte Carlo method is simple - just simulate the particle behavior. The devil is in the details, however. This course provides a balanced approach to the theory and practice of Monte Carlo simulation codes, with lectures on transport, random number generation, random sampling, computational geometry, collision physics, tallies, statistics, eigenvalue calculations, variance reduction, and parallel algorithms. This is not a course in how to use MCNP or any other code, but rather provides in-depth coverage of the fundamental methods used in all modern Monte Carlo particle transport codes. The course content is suitable for beginners and code users, and includes much advanced material of interest to code developers. (10 lectures, 2 hrs each)
