Simulation Study for Beam Extraction with an Electrostatic Einzel Lens for Low Energy Accelerator Mass Spectrometry

Radiocarbon dating using a compact or low energy accelerator mass spectrometer has been rapidly developing in recent times. A gaseous ion source was designed and simulated to reduce sample preparation times. Then, a simulation study for low-energy accelerator mass spectrometry using the designed ion source for low energy beam transport was conducted to analyze beam separation optimization. Based on our simulation results, the use of an electrostatic Einzel lens led to an enhancement in beam focusing and separation. The ion beam trajectories were calculated using a SIMION program. These simulation results for ion beam extraction are presented in this paper.
