A modified coaxial plasma gun in the high density regime of 20-70 mT of He was investigated experimentally and theoretically. Tile injection of the plasma torus into a drift space was studied by diamagnetical diagnostics both with and without helical bias, ...
This paper presents an overview of results of the 1994/95 experimental campaign on JET with the new pumped divertor and draws implications for ITER in the areas of detached and radiative divertor plasmas, the use of beryllium as a divertor target the mater ...
The TERPSICHORE three-dimensional linear ideal magnetohydrodynamic (MHD) stability code [Theory of Fusion Plasmas, Proceedings of the Joint Varenna-Lausanne International Workshop, Chexbres, Switzerland, 1988 (Editrice Compositori, Bologna, Italy, 1989), p ...
Ion and electron temperatures of up to 5 keV have been obtained within 10 cm of the last closed flux surface (LCFS) in hot ion H-modes with 18 MW of neutral beam heating. The ion temperature profiles appear to have 'pedestals' which scale with power per pa ...
We describe a few relevant aspects of the new plasma physics stability code, TERPSICHORE, which breaks new ground both in plasma theory and in its algorithmic implementation. We chose a highly accurate discrete mathematical representation which led to the ...
Alfven waves in fusion plasmas play an important role in a number of situations. First, in Alfven Wave Heating (AWH) schemes. Second, both theory and experiment have demonstrated the existence of Global Alfven Eigenmodes (GAEs). GAEs have been observed in ...
A major portion of the DIII-D program includes studies of the L-H transition, of the VH-mode, of particle transport and control and of the power-handling capability of a divertor. Significant progress has been made in all of these areas and the purpose of ...
A method of obtaining a relative calibration of Si photodiodes for the spectral range of soft x rays (1-30 KeV) is presented. A simple mathematical model of the p-n diode is adopted which allows the response to be described in terms of a small set of param ...
