First application of a tungsten single-crystal positron source at the KEK B factory
A new tungsten single-crystal target has been successfully employed at the positron source of the KEKB injector linac. The crystal thickness was determined to be 10.5 mm based on previous systematic measurements of the positron-production efficiency. The crystal axis, ⟨111⟩, was precisely aligned to...
