Abstract
THE secondary electron emission coefficient δ of evaporated titanium films has been measured at target voltages between 0 and 1,875 V with electron current densities ranging between 2 and 50 µamp/cm2. The bias voltage applied to the secondary electron collector was between 0 and +12 V. The experiments were done in an ultrahigh vacuum system made of stainless steel, sealed with aluminium wire gaskets, and pumped by a fractionating oil diffusion pump. The diffusion pump was fitted with a liquid nitrogen trap and charged with silicone 704 fluid1.
