Wave coupling and propagation from a fast-wave antenna in the lower hybrid range of frequencies

July 2025 | J. Larson | Journal of Plasma Physics | Paper

A set of experiments were conducted on the Large Plasma Device (LAPD) at UCLA to test the operational principles of a traveling wave antenna of the comb-line type. This antenna was designed to launch helicon waves (fast waves in the lower hybrid range of frequencies) on DIII-D.

Electromagnetic and Centrifugal Effects on Plasma Acceleration in the Magnetic Nozzle

July 2025 | A.I. Smolyakov | Physics of Plasmas | Paper

Plasma flow and acceleration in the converging-diverging magnetic field configuration, such as magnetic nozzle in electric propulsion and open magnetic mirrors for fusion applications are considered.

Integral expressions for self and mutual inductances of circular coils with rectangular winding cross sections

June 2025 | A. Ivanov | Review of Scientific Instruments | Paper

The method of extracting inductance based on formulas has been widely used due to its simplicity and efficiency. The literature primarily
includes various formulas for inductance, which have been derived using different approximations.
