Practical Limits on Positron Accumulation and the Creation of Electron-Positron Plasmas
Abstract
The tasks of accumulating large numbers of positrons, creating high-density positron plasmas, and confining electron-positron plasmas present a number of technical challenges. Some practical considerations and limitations of common confinement schemes are discussed. A novel design for a multi-cell Penning-Malmberg trap is proposed for the accumulation of large number of positrons (e.g.>10(exp12) and Tau ^0.5 eV). A method is described to create a low-density, electron-positron plasma (e.g., n ^ 10(exp7) /cu cm) for basic plasma physics studies that uses a combination of radio-frequency and magnetic continement. The possibilities for confinement of a hot (e.g. Tau> 10 keV) electron-position plasma in a magnetic mirror are also discussed.
