“…Ion Sources are machines that produce a stream of ion beams that can be used in the fields of particle accelerator physics, ion implantation, mass separator, controlled fusion research and for producing and/or tailoring the properties of a thin solid film [1][2][3][4][5][6][7]. They can be categorized according to their physical properties, operational parameters and applications [8][9][10]. Direct current (DC) gas discharge is self maintained by applying D.C field between the anode and cathode that immersed inside the discharge vessel in the presence of a gas at low pressures [11][12][13][14].…”

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.

“…The system uses an acceleration/deceleration scheme to avoid compensating electrons being accelerated back into the source, thus destroying its rear side and leaving the ion beam uncompensated. The main beam extraction characteristics of this Freeman type ion source system were investigated with the SIMION computer program version 7, using singly charged argon ions with and without space charge (Abdelrahman and Abdelsalam, 2011).…”

This work focuses on the design and implementation of an electrostatic lens system to produce highintensity, low-energy ion beams, by means of numerical simulation of the beam trajectories (SIMION 7). The lens design was optimized using the simulation data obtained with a performance characteristics of the electrostatic lens system. This lens system maintains good beam focal quality for the deceleration of heavy ion beams of argon ions of with space charge of 10 mA. The beam emittance and beam diameter as a function of the gap width for a decel voltage of 45 kv of a deceleration lens system for a singly charged argon ion trajectories were investigated. A gap width of 5 mm and a tube diameter of 26 mm were found to be the minimum values. Also, a minimum of 24 mm of inner tube diameter was obtained for the relation between the inner tube diameter and the beam diameter. Beam emittance and beam diameter as a function of the focusing points for a decel voltage of 45 kv of a deceleration lens system for a singly charged argon ion trajectories was studied. A minimum of 455 mm was obtained at the outer exit of the deceleration lens system. While for the beam diameter, a minimum of 460 mm was deduced. It was found also that, a minimum of V decel = 43 kV, deceleration voltage was obtained for the relation between the deceleration voltage and beam emittance. Also, a minimum of V decel = 49 kV was found for the relation between the decelration voltage and beam diameter.
