With the presumption that a shifted Maxwellian velocity distribution adequately describes the electrons in a flowing plasma, a method with optimum signal to noise resolution to measure directed velocity is described. The lowest velocity that can be d

Conventional Thomson scattering using a ruby laser evidences difficulty in scattered signal detection for electron densities10(13) cm(-3). Use of a Nd-glass laser source in combination with appropriate detectors can result in gains in the resolution

A 0·50 m long compact-toroid transport experiment (CTTX) has been studied with a number of diagnostics, including Thomson scattering, to determine local plasma properties and gradients indicative of transport processes. The CTTX bias and main field

A radiometric calorimeter is described in which the energy absorber works at the same time as a temperature sensor so that thermal equilibrium for the entire volume of absorber is not required before measuring an incident energy. The achievable frequ

A high‐resolution Fabry–Perot interferometer (FPI) has been developed to diagnose plasma with low electron line densities. The technique is based on the fact that a cavity which is undergoing a small oscillation in length will periodically pass t

In order to simulate a theta pinch experiment in which the rotational energy is estimated to be comparable to the thermal energy, plasma column rotation is included through the radial pressure balance equation in a zero-dimensional, time-dependent co

The expansion flow of helium plasma in the end loss region of a theta pinch has been studied. The accuracy of several spectroscopic techniques for determining plasma properties in the transient, inhomogeneous plasma has been evaluated. Plasma at a lo

The transient flow generated by a pulsed, megawatt-level, gas-fed arc with an applied magnetic nozzle has been examined with a new design piezoelectric pressure transducer. Sensor thermal conduction and accelerations have been examined and eliminated

In order to determine electron densities from /V (current-voltage) data, an analysis of electron collection processes in the weakly ionized, high-pressure ionosphere plasma between 40 and 80 km has been carried out. The diffusion layer concept of ion
