Abstract :
Construction of a 2.24 T-m, rapid-cycling booster synchrotron (CIS) to inject polarized ions (p,d) into the Indiana Cooler is nearing completion at IUCF. Designed to provide 2.5×1010 particles per pulse for Cooler injection, the booster is also well suited for use as a source of 60-220 MeV protons for medical therapy. An AccSys Technology Model PL-7 linac consisting of a 3 MeV RFQ coupled to a 4 MeV DTL is used to pre-accelerate H- ions to 7 MeV for strip injection into CIS. Two 350 kW, 425 MHz rf amplifiers power the linac, which accelerates variable pulse width H- beams with duty factors up to 0.2%. The linac accepts up to 1.0 π mm mrad (norm), 25 keV H- beams and accelerates them to 7 MeV with 1% energy spread and no emittance growth. Following delivery to IUCF in December, 1996, beam commissioning began in January, 1997. The measured linac beam performance characteristics from this work are presented
