Gordon Knox Film Collection: Access to Three Family Collections: How'd We Do It

This presentation discusses the digitization project of the Gordon Knox film collection. The University of North Texas (UNT) Media Library began working with the donors and assessing the project plan for digitizing this collection in 2007 and the films were made available in the UNT Digital Library in 2010. This presentation describes the strategies, initial challenges, processes, and lessons learned from working on this project.

Accelerator-based fusion with a low temperature target (open access)

Accelerator-based fusion with a low temperature target

This article reports a study of a cold target with a high Fermi energy in light of recent research that points to a new phase of hydrogen, which is hypothesized to be related to metallic hydrogen. It has been shown that if the energy transfer between injected ions and target electrons is sufficiently small, net energy gain can be achieved. As such, the target is considered to be composed of nuclei and delocalized electrons.

Dual levitated coils for antihydrogen production (open access)

Dual levitated coils for antihydrogen production

Article on theoretical and experimental efforts to use dual levitated coils to confine relatively large, cold, dense non-drifting recombining antihydrogen plasmas. The theoretical effort includes the development of a classical trajectory Monte Carlo simulation of confinement. The experimental effort includes levitation of a NdFeB permanent ring magnet, which produces a magnetic field that is qualitatively similar to the field that would be produced by the two coaxial superconducting magnetic coils.

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.

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).
