A high-pressure plasma source based on the Penning ionization of caesium by photoexcited mercury is studied by a kinetic model. Mercury vapour is photoexcited by resonant excitation at 253.7 nm to the 3P1 level, then quenched to the metastable 3P0 le

Strong microwave absorption was observed when a 10 GHz source illuminated an underdense collisional plasma that had a density gradient scale length several wavelengths long. Significant reductions in angular scattering and cross‐polarized component

A simple method to make a temperature measurement in an atmospheric-pressure plasma torch with a density of 1013 electrons/cm3 is developed. The method is based on thermal equilibrium and a detailed analysis of heat loss from a copper wire placed in

Pulse propagation in plasmas has been widely studied in relation to instabilities and their classification as convective or absolute. Such analyses emphasize the importance of considering the summation of a spectrum of modes, rather than simply makin

Dispersion characteristics deduced from a wave packet by observing its amplitude and phase at a distant point are ‘observational’ dispersion characteristics. In this paper, we demonstrate for the example of a cold beam-plasma system that differen

One-dimensional wave packets propagating through an infinite homogeneous medium may be characterized by three properties: group velocity, phase velocity, and growth or decay rate. Analysis of such wave packets excited by a periodic source maintained

Experiments carried out in Alaska with the object of observing long-delayed radio echoes (LDE) are described. The results are subjected to critical sonogram analysis, together with data form previous experiments carried out at Stanford and elsewhere.
