National Measurement Institute of Australia (NMIA) has developed a miniature crucible design suitable for measurement by both thermocouples and radiation thermometry, and has established an ensemble of five Co-C eutectic-point cells based on this des

Measurements of the effective radiance temperature of a high-temperature graphite tube black-body furnace are compared with those calculated from two theoretical models. The first model extends the conventional annular zone model by including effects

Measurements are presented of the edge wave magnetic fields generated by fast wave antennas in the TORTUS Tokamak. All measurements were made in a deuterium plasma and at frequencies in the range 2< omega / omega ci

Previous theoretical work on fast Alfven eigenmodes suggests that it is not possible for any single mode to satisfy boundary conditions in a rectangular cross-section torus, even though such modes are observed experimentally. The authors show that it

In this paper, the spectrum of fast Alfven eigenmodes is examined for a cylindrical, current‐carrying, inhomogeneous plasma, at frequencies above the ion cyclotron frequency. Although the spectrum for m=0 and m=±1 modes in a current‐free plasma

Experimental results are presented on the behaviour of Alfven surface waves at frequences of interest for ICRF heating. These waves were observed, using a poloidal array of magnetic probes, to propagate as a guided beam along steady magnetic field li

In a cylindrical, plasma-filled waveguide, the fast Alfven mode with the lowest waveguide cutoff frequency or density is the first radial m=+1 mode, where m is the azimuthal mode number. If the plasma is surrounded by a vacuum or low density region,

A formic acid laser operating at 433 μm and a gyrotron which is step-tunable in the range 75-330 GHz are being used to study density fluctuations in a small tokamak during Alfven wave heating. The scattering systems and recent results will be discus

Discrete Alfven Waves (DAWs) have been observed as antenna resistance peaks and as enhanced edge fields in the TORTUS tokamak during Alfven wave heating experiments. A kinetic theory code has been used to calculate the antenna loading and the structu
