Abstract
NEUTRAL BEAMS REQUIRE SOURCES OF NEGATIVE HYDROGEN OR DEUTERIUM IONS. A METHOD FOR PRODUCTION ON THE NEGATIVE IONS USES A BIASED NEGATIVE ION FORMING ELECTRODE WITH A LOW WORK FUNCTION SURFACE IMMERSED IN A DEUTERIUM OR TRITIUMDISCHARGE. THE LOW WORK FUNCTION SURFACE IS MAINTAINED BY ADSORBING A LAYER OF CESIUM ON THE SURFACE OF THE NEGATIVE ION ELECTRODE. MORE EFFICIENT ION PRODUCTION CAN BE OBTAINED IN THESE CESIUM-HYDROGEN DISCHARGE SOURCES, IF THE CESIUM COVERAGE ON THE NEGATIVE ION FORMATION ELECTRODE CAN BE MAINTAINED TO AVOID THE LOSS OF THE CESIUM ADLAYER BY SPUTTERING. THE PROPOSED WORK WILL DEVELOP A POROUS CESIUM DISPENSING NEGATIVE ION ELECTRODE WHICH WILL BE CAPABLE OF OPERATING AT HIGHER NEGATIVE VOLTAGES THAN THE PRESENT DEVICES, AND YET MAINTAIN ADEQUATE CESIUM COVERAGE ON THE SURFACE. THE CESIUM DISPENSING NEGATIVE ION FORMATION ELECTRODE WILL BE BUILT TO MATCH THE REQUIREMENTS OF A LAWRENCE BERKELEY LABORATORY TEST APPARATUS. AFTER THE NEGATIVE ION ELECTRODE HAS BEEN FABRICATED IT WILLBE TESTED AT LBL. THE RESULTS WILL BE REPORTED.
