The Development of a Novel Cold Electron SourceMicrochannel Plates can be modified to function as spontaneous electron emitters. These electron generators are created by altering the microstructure of the MCP channel, so that spontaneously emitted electrons can be produced, causing cascading secondary electrons. The emission current can be varied over a broad range.
