Confinement of relativistic electrons in a magnetic mirror en route to a magnetized relativistic pair plasma
Abstract
Creating a magnetized relativistic pair plasma in the laboratory would enable the exploration of unique plasma physics relevant to some of the most energetic events in the universe. As a step toward a laboratory pair plasma, here we have demonstrated an effective confinement of multi- electrons inside a pulsed-power-driven 13 magnetic mirror field with a mirror ratio of 2.6. The confinement is diagnosed by measuring the axial and radial losses with magnetic spectrometers. The loss spectra are consistent with electrons confined in the mirror for . With a source of 1012 electron-positron pairs at comparable energies, this magnetic mirror would confine a relativistic pair plasma with Lorentz factor and magnetization .
