TrapCAD modelling and EEDF studies of ECR source with new magnetic topology

by Arpan Khandelwal

Abstract: A 10GHz ECR ion source (PK-GANESA) with a new magnetic topology has been developed in a GANIL – Pantechnik collaboration [1]. The performance of this source has been analyzed through simulations of electrons prior to collisions for 20µs using TrapCAD. The EEDF obtained from the simulations has been characterized with respect to radio-frequency, heating power, and simulation time. These results have been compared to a more traditional 10GHz ECRIS (NANOGAN3) [2] present at GANIL with simulation parameters normalized to electron density. The simulation results have demonstrated an improvement of electron confinement (~10 times) with increasing RF heating. This contribution will deal with the results obtained from the simulations and their implications with regard to the PK-GANESA source.
