  This paper presents a simulation study of a permanent magnet electron
cyclotron resonance ion source (ECRIS) with a minimum-B quadrupole magnetic
field topology. The magnetic field is made to conform to conventional ECRIS
with $B_\textrm{min}/B_\textrm{ECR}$ of 0.67 and a last closed magnetic
isosurface of 1.86$B_\textrm{ECR}$ at 10 GHz. The distribution of magnetic
field gradients parallel to the field, affecting the electron heating
efficiency, cover a range from 0 to 13 T/m, being similar to conventional
ECRIS. Therefore it is expected that the novel ion source produces warm
electrons and high charge state ions in significant number. Single electron
tracking simulations are used to estimate plasma flux distribution on the
plasma chamber walls and to provide an estimate of the ion density profile at
the extraction slit then used in ion optical simulations demonstrating high
transmission through the low energy beam transport. The designed ion source is
intended to study if the quadrupole field topology could produce high charge
state beams in comparable intensities to conventional ECRIS and efficiently
transport them through a low energy beamline, thus paving the way for a
superconducting ARC-ECRIS using the same field topology. Furthermore, the
prospects of the presented ion source design as an injector of a single-ended
accelerator for ion beam analysis are discussed.
