Abstract

Cu- ion beams are produced in a Plasma Sputter Type Negative Ion Source. An Electrostatic Energy Analyzer (ESA) is used to sample the negative ion beams with energies that do not exceed 1keV. The corresponding ion currents of the beams are then calculated. Theoretical values of the sputtering yield and negative ion production probability are calculated per ion energy value and then compared to the ion current. A correlation value of 0.80021 between the experimental data and theoretical values suggests a high correlation; therefore, the ion beam is the product of the processes of sputtering and negative ion formation.
