The Internet and College Students' Motivation to Vote (open access)

The Internet and College Students' Motivation to Vote

This article investigates the impact of the political information available on-line on college students’ motivation to vote. The results illustrate that not only politicians, but educators should be cognizant of this civic engagement process. Schools and teachers of all levels are one the front lines of the battle to create a more informed, more involved citizenry; higher education has a strong influence on motivation to vote.

Confinement of antiprotons in the electrostatic space charge of positrons in a model of the ALPHA antihydrogen trap (open access)

Confinement of antiprotons in the electrostatic space charge of positrons in a model of the ALPHA antihydrogen trap

This article details the equilibrium of a positron plasma in a model of the ALPHA apparatus that is computed using a finite-difference method. The positron plasma in the model extends to axial magnetic mirrors in absence of an octupole field. Formation of a three-dimensional electrostatic potential well is found to occur self-consistently. Well depths under various conditions are evaluated. Also, the equilibrium with an antiproton plasma confined in the potential well is computed.

Giant cross-magnetic-field steps due to binary collisions between pair particles (open access)

Giant cross-magnetic-field steps due to binary collisions between pair particles

Article explores giant cross-magnetic-field steps which occur as a result of positron-electron collisions. Within a constant magnetic field (e.g., 1 T), a collision between a positron and an electron can result in a correlated drift across the magnetic field for a continuous range of impact parameters. Within this range, drift distances orders of magnitude larger than that associated with like-charge collisions were observed by computer simulation.
