A negative carbon-ion source was designed for accelerator mass spectrometry for application in the medical field to minimize cross-contamination and to increase the measurement efficiency. The ion source was designed by adjusting the distance between the plasma and the extraction electrodes and by changing the anode structure. Various prototype ion source configurations were fabricated to construct an ion source test stand to confirm the carbon beam extraction. The transport efficiency of the negative carbon beam was experimentally investigated using a filament-driven ion source to determine the geometrical effect of the anode configuration. The carbonion source was operated under carbon dioxide gas flowing at 3.0 sccm at a high voltage of −30.0 kV and an applied arc current of up to 0.5 A and various magnetic fields. The optimized anode structure and operating conditions of the ion source with the beam characteristics must be verified to measure the beam current with various ion source parameters. The effects of various operating and structural conditions on the beam current are evaluated in this article.

“…This can be done by mechanical change during electrode manufacture without need electric or magnetic fields. There are many studies on the shape of extraction electrode, but there are few specific studies on the shape of the extraction electrode aperture [11,12] present work the expression of cathode electrode aperture or plasma electrode aperture refers to the extraction electrode aperture). When the shape of an extraction aperture is changed, it will have effects on surrounding electric field, and the trace length of ion beam in the aperture.…”

This work involves a simulation study of different cathode electrode aperture shapes (pierce, reversed pierce, cone, reversed cone, triangle, reversed triangle, rectangle, circle, and sphere), which confirms that pierce and cone shapes are the best extraction apertures. The minimum values of ion beam diameter and ion beam emittance, at collector plate placed at 30 mm distance from cathode electrode, were obtained using pierce and cone shapes. Moreover, the distance of the ion beam trajectories focal point was studied using different shapes of cathode aperture, which was found to decrease with increasing the voltage applied to the cathode electrode. The main parameter in this study was the applied voltage to the cathode electrode. It was found that the observed changes on the ion beam parameters are in the range 100 -1500 V, but at charges higher than these values the behavior of diameter, emittance and focal point of the ion beam were quasi-saturated. It was also found that the general behavior of ion beam diameter and its emittance nearly the same.
