Improved tungsten moderator structures for slow positron beams

Tungsten filaments from commercial incandescent light bulbs have been tested as slow positron moderators. The filaments were annealed by electric current in the neutral gas atmosphere of the bulbs at or above the normal operating temperature of the lamp. The total efficiency of the positron source/m...
