Research Abstract

For the purpose of accumulating low energy positrons in a trap, properties of accumulating low energy and low current (a few pA) charged particles were investigated experimentally. Also, properties of non-neutral electron plasmas in a magnetic field gradient were studied. New insights were obtained in the control of radial density distribution with sideband cooling, the density and potential distribution, and the propagation of solitary waves in a magnetic field gradient.
