Popis: | A new ground state source of negative hydrogen ions with polarized nuclei (H−) is being developed at BNL. Extensive developmental research has been aimed at improving each element of (H−) production: cold H° beam, spin selection and focusing magnets, and ionizer. These elements have recently been integrated into a source. A first test with the accommodator nozzle cooled only to liquid nitrogen temperatures resulted in 5 μA of H−. Tests at liquid helium temperatures are now beginning. |
