Measurements and modeling of Alfvén eigenmode induced fast ion transport and loss in DIII-D and ASDEX Upgrade
M. A. Van Zeeland,W. W. Heidbrink,R. K. Fisher,M. Garcia Munoz,G. J. Kramer,D. C. Pace,Roscoe White,S. Aekaeslompolo,Max E Austin,J. E. Boom,I. G. J. Classen,S. da Graca,Benedikt Geiger,M.V. Gorelenkova,N. N. Gorelenkov,A.W. Hyatt,Neville C. Luhmann,M. Maraschek,George McKee,R.A. Moyer,Christopher Muscatello,Raffi Nazikian,Hyeon K. Park,S. E. Sharapov,W. Suttrop,G. Tardini,Benjamin Tobias,Y. B. Zhu,Diii-D +28 more
TL;DR: In this article, neutral beam injection into reversed magnetic shear DIII-D and ASDEX upgrade plasmas produces a variety of Alfvenic activity including toroidicity-induced Alfven eigenmodes (RSAEs) and reversed shear Alfven (RSE) during discharge current ramp phase when incomplete current penetration results in a high central safety factor and increased drive due to multiple higher order resonances.
Journal ArticleDOI
Scintillator-based diagnostic for fast ion loss measurements on DIII-D.
R. K. Fisher,D. C. Pace,M. Garcia-Munoz,W. W. Heidbrink,Christopher Muscatello,M. A. Van Zeeland,Y. B. Zhu +6 more
TL;DR: Initial DIII-D results showing prompt losses and energetic ion loss due to MHD instabilities are discussed.
Journal ArticleDOI
Characterization of off-axis fishbones
W. W. Heidbrink,M. E. Austin,R. K. Fisher,M. Garcia-Munoz,G. Matsunaga,G. R. McKee,R. A. Moyer,Christopher Muscatello,M. Okabayashi,D. C. Pace,K. Shinohara,W. M. Solomon,E. J. Strait,M. A. Van Zeeland,Y. B. Zhu +14 more
TL;DR: In this article, the authors observed a burst in high-beta, beam-heated plasmas with safety factor q > 1 in the DIII-D tokamak, where the off-axis fishbones are similar to the q = 1 fishbones first observed on the Poloidal Divertor Experiment (PDX).
Journal ArticleDOI
Discovery of stationary operation of quiescent H-mode plasmas with net-zero neutral beam injection torque and high energy confinement on DIII-D
Keith H. Burrell,Kshitish Barada,Xi Chen,A.M. Garofalo,Richard J. Groebner,Christopher Muscatello,Tom Osborne,Clinton C. Petty,Terry Rhodes,P. B. Snyder,W. M. Solomon,Zheng Yan,Lei Zeng +12 more
TL;DR: In this paper, the edge turbulence was modified to achieve stationary, high confinement operation without edge localized mode (ELM) instabilities and with no net external torque input, which achieved an additional confinement challenge that is usually difficult at low torque.
Journal ArticleDOI
Central flattening of the fast-ion profile in reversed-shear DIII-D discharges
W. W. Heidbrink,M. A. Van Zeeland,Max E Austin,K. H. Burrell,Nikolai Gorelenkov,G. J. Kramer,Y. Luo,M. A. Makowski,George McKee,Christopher Muscatello,Raffi Nazikian,E. Ruskov,W. M. Solomon,Roscoe White,Y. B. Zhu +14 more
TL;DR: In this article, fast-ion Dα (FIDA) spectroscopy was applied to the DIII-D tokamak to study the toroidicity-induced and reversed-shear Alfven eigenmodes.
