Enhancing Plasma Dynamics Modeling in RF Ion Sources Using Improved PIC Simulations and Refined Cross-Section Data

This study utilizes computational plasma modelling using a Particle-in-Cell computer program to simulate and compare hydrogen and deuterium in a volume-cusp ion source to ascertain why H¯ and D¯ output beams beam production ratio is ~3:1 [3-5]. To the best of our knowledge a comprehensive modelling study does not exist explaining this effect. This project will provide an important example regarding PIC code utility in shedding light on measurable plasma phenomena. Partner D-Pace develops, manufactures and sells ion sources. D-Pace has worked to experimentally improve the output of its D¯ beams (relative to H¯) with limited success. The challenge is to utilize the PIC/MCC computational plasma modelling code to simulate the H¯ and D¯ cases to: (i) better understand the underlying mechanisms in the plasma that contribute to the production difference, and (ii) to ascertain next experimental steps based on simulation that would yield increased relative D¯ production. The benefit to the partner company D-Pace would be improved H¯ and D¯ ion source products (particularly D¯) for medical cyclotrons used to produce radioisotopes for the diagnosis and therapy of cancer.
