Abstract : The collection of very low velocity electrons by metallic surfaces in a complex phenomenon and merits further study. Contamination is always present and may be a powerful factor in the behavior of a particular surface. The electrons rejected by a surface influence the characteristics of electron deviced in many ways, among there being the macroscopic phenomenon known as ''Black out'' as well as second oder effects such as gain variation in DC amplifiers, frequency drift in oscillators, and nose in high gain amplifiers.
