Abstract : The report summarizes the physical assumptions used in BETA 2, a Monte Carlo computer program for bremsstrahlung and electron transport analysis in complex geometries. The program is written in Fortran 4 for the CDC 6600, IBM 360, and UNIVAC 1108 computers. The BETA 2 program is designed primarily for electron energy deposition calculations but is also applicable to photons. The condensed history Monte Carlo technique is employed for electrons and the effects of fixed electric and magnetic fields or self-generated electric fields are also included. Results are presented for sample calculations of electron angular distributions, energy deposition profiles, bremsstrahlung production, and multi-dimensional energy deposition profiles with and without electric and magnetic fields. Where possible, comparisons are made with experimental data. The users manual for the BETA 2 program is contained in a companion volume. (Author)
