Abstract

The South Hall Ring at the MIT-Bates Linear Accelerator Center is a combination of pulse stretcher ring to produce high duty factor extracted beams and storage ring for use with internal targets. It is designed to operate at energies from 300 MeV to 1 GeV for nuclear physics experiments. In pulse stretching mode, half-integer resonant extraction is used to convert the <1% duty factor beam from the linac into near CW beam. To date, we have extracted beams with duty factors in excess of 50%, and high throughput efficiencies. The first nuclear physics experiments using extracted beam are planned for the near future. Details of commissioning the ring for extracted beam operation are presented
