Plasma‐induced bubbles respond to time‐dependent injection of energy which modifies the acoustic output relative to ‘‘classical’’ gas bubbles. Additionally, they consist primarily of hot vapor which complicates the thermodynamics, elevate

For times long compared to the acoustic wave transit time in a test tank, the signal from point acoustic sources may be dominated by internal reflections and the modal response of the experimental tank in which experiments are performed. If the free

Conventional low‐frequency transducers are rather bulky, of limited efficiency, and may suffer from cavitation at high source levels. Plasma‐induced bubble transducers may offer improvement in some of these limiting factors. An implementation met

This paper examines various schemes by which an intense pulsed ion beam can be injected into a tokamak. There are several schemes which appear to be viable just as the plasma is being formed, but which cannot work for a steady-state plasma. All schem

In fusion reactor systems, the reaction rates are calculated from a velocity-space integral over the reaction cross section times the distribution functions of the reacting species. In a plasma, the shape of the distribution functions themselves is d

A numerical model has been developed to study the confinement of low-pressure plasmas in simple axially symmetric configurations. The equations contain the effects of resistivity, plasma inertia, and pressure gradients along the field. The model is a

Publisher Summary Large-scale computational simulations of physical systems have become a valuable adjunct to theoretical and experimental research efforts in the physical and chemical sciences. They are essential because the computer allows solution

The interactions of runaway electrons with the anomalous‐Doppler‐shifted mode and a bump‐on‐tail mode are studied numerically using the Fokker–Planck equation with a self‐consistent quasi‐linear diffusion operator. It is shown that a ve

In toroidal systems with geodesic curvature an electrostatic acoustic mode occurs with plasma motion in the magnetic surfaces, perpendicular to the field. In typical stellarators this mode should dominate ordinary sound waves associated with motion a
