Possible Antihydrogen Trapping Field and Nonneutral Plasma Density Limits

摘要

Axisymmetric magnetic field configurations are being considered for trapping anti-hydrogen atoms that are recombined in Penning traps. As part of an effort to understand the nonneutral plasma confinement properties of axisymmetric configurations, which necessarily have radial field components, plasma confinement within a magnetic field that is purely radial is studied. Various density limits of nonneutral plasmas confined in radial magnetic fields are evaluated and compared to those of plasmas confined in axial magnetic fields.
