Lj. Lorence et al., ADJOINT ELECTRON-PHOTON TRANSPORT MONTE-CARLO CALCULATIONS WITH ITS, IEEE transactions on nuclear science, 42(6), 1995, pp. 1895-1901
A general adjoint coupled electron-photon Monte Carlo code for solving
the Boltzmann-Fokker-Planck equation has recently been created. It is
a modified version of ITS 3.0, a coupled electron-photon Monte Carlo
code that has worldwide distribution. The applicability of the new cod
e to radiation-interaction problems of the type found in space environ
ments is demonstrated.
