摘要

A target for generating fast neutrons by the reaction 37 Li (p, n) 47 Be consists of a thin lithium foil 30 supported within an evacuated beam tube 10 by a water-cooled support structure 12. Gaps 24 in the support structure 12 are bridged by the foil 30, and in use a proton beam is scanned over these bridging portions of the foil. IMAGE
