Summary: | Ionization of working species up to high charge states in Electron Beam/String Ion Sources (EBIS/ESIS) is provided by electron impact; a primary electron beam of a corresponding energy, compressed in a strong external solenoidal magnetic field, is produced by an immersed electron gun containing a thermionic electron emitter assembly as its key element. Control and monitoring of parameters in cathode assembly are provided by special electronics designed by the JINR NICA [1] accelerator division engineers. In this report we describe Electron String Ion Sources (ESIS) development short history and its main working principles as a basic start point. The designed new cathode assembly electronics development and production as well as its operational principles are described and discussed in some details. |
