Design and simulation study of a simple ion injector

The stated purpose of this manuscript is to study the parameters of a single-gap accelerator system with a view to optimizing the transport of a beam of argon ions. A study is made for the main factors that must be considered on the design of an ion injector taking into account the appropriate design of the single gap accelerator column by doing such study both analytically and with ion beam simulation. These study shows the dependence of the optimal voltage ratio which is related to the minimum beam emittance depends on the column dimension. Study of analytical calculations was done without space charge while simulation processes with space charge effect. Study of optical ion beam properties for a single gap accelerating column was done by using a SIMION computer program. A series of simulation studies were made in order to determine optimum conditions for acceleration of space-charge-dominated argon ion trajectories with incident energy of 50 keV from a distance 150 mm of the ion source at constant gradient acceleration system.   Key words: SIMION computer program, single gap tube acceleration system, beam emittance, injector system.
