McTrap, a program for the computation of radiation trapping in 3-level atoms including bleaching effects
Description
Abstract McTrap computes radiation trapping including bleaching effects and particle diffusion in a two-dimensional cylinder geometry. It combines Monte Carlo simulations of radiation trapping and analytical solutions of the diffusion equation for a highly efficient computation of the distribution of excited atoms. The spectral lineshapes can be freely chosen. Commonly occurring special cases, like two-level atoms, one-dimensional geometries (plane-parallel slab and infinite cylinder) etc. can also si... Title of program: McTrap Catalogue Id: ADCC_v1_0 Nature of problem Computation of the bleaching of ground state atoms in 3-level atoms in a two-dimensional cylindrical cell, with inclusion of particle diffusion, and of nonlinear trapping in such a geometry. The program can be easily specialized to treat the simpler, more usual radiation trapping problems.
