Saddle field gun
Compact ion and fast atom sources for use when small size and high beam intensity are required, as in fast atom bombardment mass spectrometry. The discharge is produced by electrons oscillating between two cold cathodes in an electric field that possesses a single saddle point. To produce and intensify the plasma the electrons must have long path lengths, achieved by allowing the electrons to have an oscillatory motion in the saddle-shaped electric field between the cathodes separated by the anode.
