WebNov 19, 2024 · Here, we discuss modeling one of the earliest electrode configurations that was devised to counteract this electrostatic repulsion: the Pierce electron gun. Electron Gun Design. A good electron gun design must be able to do the following: Extract a sufficiently high number of electrons; that is, get an adequate beam current WebABSTRACT The problem of determining the Pierce electrodes in a gun reduces to a Cauchy problem on Laplace's equation. The questions of existence, uniqueness and instability of solutions to general problems of this type are considered, together with their relevance to the design of electron guns. A general procedure for solving a Cauchy problem is …
