Secondary electron emission properties and characteristic energy losses from some metals

Thomas, Simon

Abstract

Secondary electron emission yield and characteristic energy losses from a number of metals have been measured in the present investigation. Owing to the known adverse effects of poor vacuum conditions and any consequent contamination of the surface on the secondary emission properties, all experiments have been conducted in a clean ultra-high vacuum environment - typical pressure under operating conditions being < 10-9 torr and the residual gases analysed by a quadrupole residual gas analyser. Total yield has been measured from Ni, Ag, Pt, Bi and TaC. A quantitative assessment of the variation of
the total yield
