Stripping Injection Into The New Booster Ring At Iucf

To increase the polarized proton beam intensity in the IUCF Cooler ring, this ring will be equipped with a new injector consisting of a 7 MeV linear accelerator and an 80 MeV Cooler Injection Synchrotron (CIS). The linear accelerator will accelerate negative hydrogen ions which will be strip-injected into CIS. Tracking calculations have been made to estimate the beam intensity that can be achieved within a specified emittance. I. STRIPPING INJECTION OF H # INTO CIS The choice of injection mode in CIS is dictated by the still modest intensity available from present polarized ion sources. While the pulsed beam intensity capabilities of modern polarized H # and D # sources is impressive (# 200 #A) and growing, it is still about a factor of 20 smaller than required for single turn kick injection to provide the 2#5 # 10 10 particles desired for Cooler injection. This goal can only be achieved via stripping injection of polarized H # and D # ions. Negative polarized hydrogen..
