Simulation Of An Antihydrogen Gravity Experiment Utilizing Multiple Apertures (open access)

Simulation Of An Antihydrogen Gravity Experiment Utilizing Multiple Apertures

The article presents an analytical model and a Monte Carlo simulation of an antihydrogen gravity experiment that would employ multiple apertures. The model was developed with the primary goal of reducing the experimental run time necessary to determine the direction of free fall acceleration for antimatter in the gravitational field of the Earth. The experiment would confine cryogenic antihydrogen plasma for producing antihydrogen (e.g., by three-body recombination).

Spatially Periodic Electromagnetic Force Field For Plasma Confinement and Control

In this article, a theoretical understanding is developed of the single-particle reflection properties of a force field, considering the incident charged particles to have a non-drifting, isotropic velocity distribution. Classical trajectory Monte Carlo simulations and analytical modeling are employed. The initiation of an experimental effort to study force fields is described.

Electrostatic storage ring with focusing provided by the space charge of an electron plasma (open access)

Electrostatic storage ring with focusing provided by the space charge of an electron plasma

Article describes an electronic storage ring that employs the space charge of an electron plasma for focusing. An advantage of the present concept is that slow ions, or even a stationary ion plasma, can be confined. The concept employs an artificially structured boundary, which is defined at present as one that produces a spatially periodic static field such that the spatial period and range of the field are much smaller than the dimensions of a plasma or charged-particle beam that is confined by the field.
