1. An axial magnetic field prevents space charge spreading of the beam. 2. Ionic relaxation comprises ionic conductivity and interfacial and space charge relaxation. 3. The electrons escape from the metal and are considered space charge . 4. The streamers transfer charge between the leaders and toroid to nearby space charge regions. 5. The perveance defines the space charge limited current that can be emitted from a device. 6. Air space charges are based on weight at takeoff and distance traveled over a country. 7. Space charges can also occur within dielectrics.8. The gas filling provides ions for neutralizing the space charge and allowing high currents at lower voltage. 9. Space charges can also occur within solid or liquid dielectrics that are stressed by high electric fields.10. The higher momentum resists space charge effects.
