The energy component analyzer and spectrum analysis of end‐loss ions in a tandem mirror

Features of the electrostatic energy analyzer of a cylindrical type are described with the aim of measuring the end‐loss ions in the tandem mirror GAMMA 10. The analyzer provides us with information about ion density distributions in a loss‐cone region of velocity space as well as plug potential in the tandem mirror. Application of the analyzer to the tandem mirror experiments and the energy spectrum analysis are discussed.
