A Haeberli-type pulsed polarized negative hydrogen source has been brought into operation at the BNL Alternating Gradient Synchrotron. It operates reliably at beam currents sometimes as high as 25 ..mu..A and 20 keV in beam pulses of 500 ..mu..sec with approximately 75% polarization. These beam intensities are about an order of magnitude higher than the original Haeberli source built at the University of Wisconsin. This improvement is caused by the higher densities of both the atomic hydrogen beam and the cesium beam, which are the basic ingredients in the charge exchange reaction. About half the beam (10 to 15 ..mu..A) is accelerated in the 200 MeV linac and injected into the AGS. 3 references, 3 figures.
