Abstract :
The pulsed polarized negative ion source (CIPIOS) for the Indiana University Cooler synchrotron produces multi-milliampere beams for injection into the Cooler Injector Synchrotron (CIS). In normal operation, the unpolarized beam intensity at the source has exceeded 30 mA peak and for polarized H- and D- beams over 1.5 mA peak. The FWHM of the beam pulse is 150 μs, the emittance for 90% of the beam is less than 1.5 B-mm-mr normalized and the nominal polarization is 80% or greater for both beams. At these peak intensities, the source operates between 0.8 Hz and 2 Hz. At greater repetition rates, the peak polarized beam intensity decreases slowly
