LITIUMSTRALMAL OCH BESTRALARE FOR BESTRALNING AV STYCKEMALM FOR ATT DETEKTERA FOREKOMSTEN AV ETT UTVALT EMNE

摘要

A target for generating fast neutrons by the reaction 3<7> Li (p, n) 4<7> Be consists of a thin layer 12 of lithium coated onto a water-cooled plate 14 of hydrogen porous material eg niobium or copper. No significant degree of alloying occurs at the interface, and hydrogen diffuses fast enough through the plate 14 for bubbles not to form at the interface when the layer 12 is bombarded by protons.
