Artificially structured boundary for confinement of effectively unmagnetized cryogenic antimatter plasmas (open access)

Artificially structured boundary for confinement of effectively unmagnetized cryogenic antimatter plasmas

The article is from conference proceedings that discuss an artificially structured boundary (ABS) considered to consist of a spatially periodic arrangement of electrostatically plugged magnetic cusps. As envisioned, a non-neutral positron plasma could be confined by an ASB along its edge, and the space charge of the positron plasma would serve to confine an antiproton plasma. If the conditions of the two-species plasma are suitable, production of antihydrogen via three-body recombination for antimatter gravity studies may be possible.

Magnetic plasma expulsion (open access)

Magnetic plasma expulsion

The article presents one scheme for what is referred to as magnetic plasma expulsion, which would prevent the plasma from entering a given region. Magnetic plasma expulsion techniques may allow instrumentation access to the interiors of plasmas. Magnetic plasma expulsion techniques may also make alternative approaches for magnetic plasma confinement possible. Particle-in-cell simulation with the Warp code is used to study magnetic plasma expulsion. Some conditions for achieving magnetic plasma expulsion are reported.
