Journal ArticleDOI
Excitation, propagation, and damping of electron Bernstein waves in tokamaks
Abhay K. Ram,S.D. Schultz +1 more
TL;DR: Ono et al. as mentioned in this paper proposed to use electron Bernstein waves (EBW) for core heating in high-β spherical tokamak plasmas, like the National Spherical Torus Experiment.
Journal ArticleDOI
Benchmarking of codes for electron cyclotron heating and electron cyclotron current drive under ITER conditions
R. Prater,Daniela Farina,Yu. Gribov,R. W. Harvey,Abhay K. Ram,Y. R. Lin-Liu,Emanuele Poli,Alexander Smirnov,Francesco Volpe,E. Westerhof,A. Zvonkov +10 more
TL;DR: The approach used in this benchmarking study is to apply these codes to a small number of representative cases, finding that following minor remedial work on some codes, the agreement between codes for off-axis application is excellent.
Journal ArticleDOI
The cusp map in the complex-frequency plane for absolute instabilities
TL;DR: In this article, it is shown that a simple topological relationship between these points and the image of the real k axis determines the stability characteristics of the system, without mapping from the ω plane back into the k-plane.
Journal ArticleDOI

TL;DR: The National Spherical Torus Experiment (NSTX) as mentioned in this paper has been used to understand basic toroidal confinement physics at low aspect ratio and high βT in order to advance the spherical torus (ST) concept.
Journal ArticleDOI
Charged-particle acceleration and energy loss in laser-produced plasmas
Damien Hicks,C. K. Li,Fredrick Seguin,Abhay K. Ram,J. A. Frenje,R. D. Petrasso,J. M. Soures,V. Yu. Glebov,D. D. Meyerhofer,S. Roberts,C. Sorce,C. Stöckl,T. C. Sangster,T. W. Phillips +13 more
TL;DR: Boehly et al. as mentioned in this paper used a simple model for the accelerating field region, and the time history of the target electrostatic potential was found and shown to decay to zero soon after laser irradiation was complete.
