A superconducting LINAC to be injected with heavy-ion beams from the Stony Brook FN tandem is described. The basic LINAC elements are lead-plated copper split-loop resonators operated at a frequency of 150 MHz and a temperature of 4.2 K. With the anticipated effective accelerating gradient of 3.0 MV/m, the booster will provide an energy gain of 20 MeV per charge for (Q=19) /sup 58/Ni ions, and have a useful mass range of A=16 to about A=100. The linac structure consists of compact independent cryostat modules separated by room temperature quadrupole doublets, each module containing four (..beta..=0.055) or three (..beta..=0.10) independently phased resonators. The tandem beam is bunched at the 16th subharmonic (pulse spacing 107 nsec) to facilitate lifetime and flight time measurements. A post-tandem rebuncher system compresses these bunches into less than +-6/sup 0/ around the -20/sup 0/ mean phase of the LINAC. Existing room geometry dictates charge selection after the first as well as the second stripping. A ..beta..=0.055 prototype cavity has already been operated with beam and successfully stabilized to +-0.1/sup 0/ in phase with a computer-controlled RF feedback system. A prototype module of 4 such cavities in a common cryostat is presently under construction.
