Abstract
The past six-month period saw completion of our program of cyclotron commissioning, with the extraction on 1992 October 14 of a 3.0 MeV/u beam of {sup 238}U. In three years were developed the cyclotron and its subsystems to demonstrate the full range of operating parameters, and they converted what was, in effect, a prototype accelerator into a fully engineered, reliable facility. The number of available beams was increased from two, to forty-two. Currently, we are adding one or two new beams per month. In spite of the commissioning activity during the reporting period, the number of cyclotron-based experiments has increased. Reaction studies and atomic-physics experiments dominated. Perhaps the outcome of broadest interest was the production and detection of secondary (radioactive beams downstream from a gold target bombarded by 40 MeV/u {sup 12}C from the cyclotron). Including beam development, the cyclotron operated for 967 hours, or 32% of the total facility beam time, about the same percentage as in the previous six-month period. Between July and the end of the year, Tandem beams were used, either for experiments or development purposes, for a total of 3117 hours. This beam time was 86% of the scheduled operating time and 71% of the
