Abstract :
Development of an intense polarized H- source for the AGS continues at Brookhaven National Laboratory. Initial tests with about one milliampere, 40 keV pulsed neutral cesium beam, colliding with more than two milliampere polarized hydrogen atoms, produced about one-half microampere polarized negative ions, extracted at 20 keV. A new pulsed cesium source with an anticipated output of 5-15 mA and an improved neutralizer are under construction.
