Abstract
The phase of injection of the electrons in a Malmberg-Penning trap is investigated both experimentally (in the ELTRAP device) and numerically. The resulting plasma density distribution is studied by varying the source parameters, the external magnetic field strength, the time of injection of the electrons and the axial position of the external potential barrier. The observed processes are interpreted using a three-dimensional particle-in-cell code which solves the drift-Poisson system where kinetic effects in the motion parallel to the magnetic field are taken into account.
