Description
Relaxation process of a pure electron plasma generated by injecting an electron beam into a Malmberg-Penning trap is experimentally investigated in this article. An abrupt broadening of the axial energy distribution function was observed at a holding time of 1 μs. This relaxation occurred faster than the expected time scale of Coulomb collisions. As shown by the experiments, the broadening of the energy profile was enhanced by the weak confinement electric field at the axial reflection point of electrons. (author)
