Abstract

ABSTRACT
A cold cathode Penning ion source was designed and operated at the optimum
conditions. Its characteristics were determined using nitrogen and argon gases at
pressure equal to 9×10-4 mmHg. Efficiency of this ion source was determined
using nitrogen and argon gases. Also, ion source aspect ratio was determined
using argon gas. The effect of negative voltage applied on Faraday cup using
argon gas was studied. Finally, a simple retarding electrostatic field energy
analyzer has been designed to determine the ion energy distribution.
