Status of the IUCF cooler injector synchrotron

Construction of a 2.24 T-m, rapid-cycling booster synchrotron is nearing completion at IUCF designed to accelerate protons to 220 MeV, it will replace the k200 isochronous cyclotron as an injector of polarized light ion beams (p,d) into the Indiana Cooler. The CIS (cooler injector synchrotron) will fill the Cooler to about 10¹¹ protons in a few seconds for research. At 30 months into the construction program, all major ring elements are fabricated, assembled, installed and in some cases, commissioned. Ring strip injection and accumulation studies began in March, 1997, ramping studies will start in June, 1997 and Cooler injection studies are planned for late 1997. The status of the construction project and initial beam injection and commissioning results are presented
