Enhanced D-Alpha H-mode Studies in the Alcator C-Mod Tokamak (2008)

E. Marmar, R. L. Boivin, C. Fiore, J. Goetz, R. Granetz, M. Greenwald, ...

Abstract. A favorable regime of H-mode confinement, seen on the Alcator C-Mod tokamak is described. Following a brief period of ELM-free H-mode, the plasma evolves into the Enhanced D-Alpha (EDA)...

Energetic particle physics studies on Alcator C-Mod (2007)

Snipes, J. A., Basse, N., Bonoli, P., Boswell, C., Edlund, E., Fasoli, A., ...

Energetic particle physics is studied in Alcator C-Mod in reactor relevant regimes with high density and equilibrated electron and ion temperatures. Stable Alfven eigenmodes are excited with...

Recent progress on the development and analysis of the ITPA global H-mode confinement database (2007)

McDonald, D. C., Cordey, J. G., Thomsen, K., Kardaun, Ojwf, Snipes, J. A., Greenwald, M., ...

This paper describes the updates to and analysis of the International Tokamak Physics Activity (ITPA) Global H-Mode Confinement Database version 3 (DB3) over the period 1994-2004. Global data, for...

Chapter 2: Plasma confinement and transport (2007)

Doyle, E. J., Houlberg, W. A., Kamada, Y., Mukhovatov, V., Osborne, T. H., Polevoi, A., ...

The understanding and predictive capability of transport physics and plasma confinement is reviewed from the perspective of achieving reactor-scale burning plasmas in the ITER tokamak, for both core...

Active and fast particle driven Alfven eigenmodes in Alcator C-Mod - art. no. 056102 (2005)

Snipes, J. A., Basse, N., Boswell, C., Edlund, E., Fasoli, A., Gorelenkov, N. N., ...

Alfven eigenmodes (AEs) are studied to assess their stability in high density reactor relevant regimes where T(i)approximate to T-e and as a diagnostic tool. Stable AEs are excited with active...

Active and fast particle driven Alfven eigenmodes in Alcator C-Mod (2005)

Snipes, J. A., Basse, N., Boswell, C., Edlund, E., Fasoli, A., Gorelenkov, N. N., ...

Alfven eigenmodes (AEs) are studied to assess their stability in high density reactor relevant regimes where T(i)approximate to T-e and as a diagnostic tool. Stable AEs are excited with active...

Scaling of the energy confinement time with beta and collisionality approaching ITER conditions (2005)

Cordey, J. G., Thomsen, K., Chudnovskiy, A., Kardaun, Ojwf, Takizuka, T., Snipes, J. A., ...

The condition of the latest version of the ELMy H-mode database has been re-examined. It is shown that there is bias in the ordinary least squares regression for some of the variables. To address...

Initial active MHD spectroscopy experiments exciting stable Alfven eigenmodes in Alcator C-Mod (2004)

Snipes, J. A., Schmittdiel, D., Fasoli, A., Granetz, R. S., Parker, R. R.

A pair of toroidally localized in-vessel antennas in Alcator C-Mod were used to excite and detect stable toroidal Alfven eigenmode (TAE) resonances in the frequency range of 400-500 kHz. By ramping...

ELM moderation with ICRF heating on JET (2002)

Maddison, G. P., Snipes, J. A., Chareau, J. M., Conway, G. D., Hutchinson, I. H., Ingesson, L. C., ...

A high-density, ELM-free, 'enhanced Dalpha' (EDA) H-mode has been demonstrated with Ohmic or RF heating on the Alcator C-Mod device. An allied 'low particle confinement' H-regime was also observed...

DEGAS 2 Neutral Transport Modeling of High Density, Low Temperature Plasmas (1997)

D. P. Stotler, A. Yu. Pigarov, S. I. Krasheninnikov, B. LaBombard, B. Lipschultz, ...

Neutral transport in the high density, low temperature plasma regime is examined using the degas 2 Monte Carlo neutral transport code. Degas 2 is shown to agree with an analytic fluid neutral model...

Global Sawtooth Instability Measured by Magnetic Coils in the Jet Tokamak (1992)

Duperrex, P. A., Pochelon, A., Edwards, A. W., Snipes, J. A.

The paper describes measurements of the sawtooth instability in JET, in which the instability wave function is shown to extend to the edge where it is measured using magnetic coils. The numerous...
