Popis: | A new optically pumped polarized H− ion source (OPPIS) was developed for the RHIC polarization program and successfully used for the first polarized beam commissioning at RHIC. The OPPIS produces in excess of 1.0 mA H− ion current at about 80% polarization. An ECR primary proton source development and a new 29 GHz microwave power supply are described. A new type sodium-jet ionizer cell is biased to −32 kV to produce a 35 keV polarized beam ready for injection to the RFQ. Higher current and higher polarization were also obtained with the biased jet-cell in comparison with an old oven-type ionizer cell. |
