Title: Scenario development for high β_p low torque plasma with q_min above 2 and large-radius internal transport barrier in DIII-D

Abstract

Here, we demonstrate graded band gap perovskite solar cells with conversion efficiencies averaging 18.3%, with a best of 21.1%, all without reflective coatings. An analysis of the experimental data yields high fill factors of ~75% and high short circuit current densities up to 46.2mA/cm². These cells display the highest efficiency ever reported for perovskite solar cells.

Fast-ion transport in q_min >2, high-β steady state scenarios on DIII-D

Journal Article Holcomb, Christopher T. ; Heidbrink, William W. ; Ferron, John R. ; ... - Physics of Plasmas

Results from experiments on DIII-D [J.L. Luxon, Fusion Sci. Technol. 48, 828 (2005)] aimed at developing high β steady-state operating scenarios with high- q_min confirm that fast-ion transport is a critical issue for advanced tokamak development using neutral beam injection current drive. In DIII-D, greater than 11 megawatts of neutral beam heating power is applied with the intent of maximizing β_N and the noninductive current drive. However, in scenarios with q_min > 2 that target the typical range of q₉₅ = 5-7 used in next-step steady-state reactor models, Alfvén eigenmodes cause greater fast-ion transport than classical models predict.

Investigation of energy transport in DIII-D High- β _P EAST-demonstration discharges with the TGLF turbulent and NEO neoclassical transport models

Journal Article Pan, C. ; Staebler, G. M. ; Lao, L. L. ; ... - Nuclear Fusion

Energy transport analyses of DIII-D high-β_P EAST-demonstration discharges have been performed using the TGYRO transport package with TGLF turbulent and NEO neoclassical transport models under the OMFIT integrated modeling framework. Ion energy transport is shown to be dominated by neoclassical transport and ion temperature profiles predicted by TGYRO agree closely with the experimental measured profiles for these high- β_P discharges. Ion energy transport is largely insensitive to reductions in the E × B flow shear stabilization. The Shafranov shift is shown to play a role in the suppression of the ion turbulent energy transport below the neoclassical level. Electron turbulentmore »« less
