Abstract : The report covers the second phase of a program, now in progress at MAGI, to develop procedures for the automatic generation of importance functions for use in three-dimensional Monte Carlo radiation transport codes. The availability of an automatic importance sampling technique will result in significant savings in the time and cose required to run a complex Monte Carlo program. It will also reduce or eliminate the possibility that a wrong answer will be obtained due to incorrect importance sampling. The emphasis during this phase was on analytical studies and the development of techniques, rather than on code development. This approach was necessary, since much of the technology did not exist for immediate code development at the start of the program. As a consequence, the codes that were developed were treated as experimental vehicles to test out the technical ideas presented, rather than an production programs. Furthermore, the emphasis in the code development was in those areas where qualitative ideas had to be tested out and made quantitative, as opposed to implementing known techniques. (Author)
