Electrostatic equilibria of non-neutral plasmas confined in a Penning trap with axially varying magnetic field (open access)

Electrostatic equilibria of non-neutral plasmas confined in a Penning trap with axially varying magnetic field

This article describes a procedure for computing the electrostatic equilibria of non-neutral plasmas in a Penning trap with a nonuniform magnetic field by solving Poisson's equation using an iterative method. Plasma equilibria in a model Penning trap with high and low field regions are computed. The plasma is assumed to follow the Boltzmann density distribution along magnetic field lines.

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.

Energy Conversion During Expansion of a Solid-Particle-Entrained Gas (open access)

Energy Conversion During Expansion of a Solid-Particle-Entrained Gas

This article describes pneumatic energy being converted into solid particle kinetic energy as a solid-particle-entrained gas that flows downward through a vertical nozzle. For the conditions studied, the solid particles serve as a heat exchange medium to enable a gas expansion that is nearly isothermal. Also, the kinetic energy associated with the two-phase fluid is predominantly that associated with subsonic solid-particle motion. The kinetic energy of the solid particles is converted into other forms using a low-speed turbine. A theoretical description of the process is presented, and the initiation of an experimental effort to study the process is described.

Entropy Balance in the Expanding Universe: A Novel Perspective (open access)

Entropy Balance in the Expanding Universe: A Novel Perspective

The article describes cosmic expansion as correlated with the standpoints of local observers’ co-moving horizons. In keeping with relational quantum mechanics, which claims that quantum systems are only meaningful in the context of measurements, the authors suggest that information gets ergodically “diluted” in our isotropic and homogeneous expanding Universe, so that an observer detects just a limited amount of the total cosmic bits.
