[en] A study of rf fueling, rf anchor, hot electron anchor, rf start up and rf-sustained mode operation in Tandem Mirrors has been completed. Significant results include finding little performance difference between inboard and outboard antenna location, and an optimum central cell electron to ion temperature ratio of between one and two. TARA hot electron anchor results compare well with the predictions of Kesner et al, but suggest that the ICRF resonance should be located at the potential peak. Several variance reduction techniques, improved rf operators and a Monte Carlo neutral model have been incorporated in the code, which has also been converted and optimized for NMFECC Cray operation. On going activities include studies of central cell ICRF heating and the application of Monte Carlo non-Maxwellian scattering operators
