Notes:
A retarding potential technique has been employed to select electrons for extraction from a hollow cathode discharge. In "normal'' operating pressures, the electron distribution function is Gaussian like with a superthermal tail. At low operating pressures, the electron distribution function has an additional distinct component of electrons with a very low thermal spread of 0.13 eV and an energy corresponding to the cathode potential.
