A May 2010 paper discussed a small device's ability to capture electrons. The paper posited that the machine had an ideal magnetic field strength that maximized its ability to catch electrons. The paper analyzed polywell magnetic confinement using analytical solutions and simulations. The work linked the polywell magnetic confinement to magnetic mirror theory. The 2011 work used Particle-in-cell simulations to model particle motion in polywells with a small electron population. Electrons behaved in a similar manner to particles in the biconic cusp.
