Bohm diffusion
Webin Monte Carlo codes, namely QLT and Bohm diffusion. As we will show below, the results of the QLT approximation are sensitive to the timescale over which the diffusion is … WebIt was first observed in 1946 by David Bohm, E. H. S. Burhop, and Harrie Massey while studying magnetic arcs for use in isotope separation. It has since been observed that many other plasmas follow this law. Fortunately there are exceptions where the diffusion rate is lower, otherwise there would be no hope of achieving practical fusion energy.
