Gyrokinetic simulation of the effect of transient fueling on plasma turbulence in ADITYA-U tokamak
Jaya Kumar Alageshan, Suman Dolui, Joydeep Ghosh +8
The gradient-driven microturbulence in ADITYA-U tokamak plasmas has been suppressed by injecting short gas puffs. The suppression of microturbulence increases the core temperature…
Effect of static magnetic island on ITG of ADITYA-U tokamak
Vibhor Kumar Singh, Amal R Biju, Jaya Kumar Alageshan +10
Magnetic islands play a crucial role in regulating plasma confinement in tokamaks by interacting with micro-instabilities, such as the ion temperature gradient (ITG) mode. This wor…
Dependence of Core Turbulence and Transport in DIII-D QH-Mode Plasmas
Abhishek Tiwari, Kshitish Barada, Jaya Kumar Alageshan +6
This study investigates the effect of the ion-to-electron temperature ratio () on microturbulence driven transport in Quiescent H-mode (QH-mode) plasmas in the DIII-D toka…
Zonal flow suppression of turbulent transport in the optimized stellarators W7-X and QSTK
Abhishek Tiwari, Joydeep Das, Jaya Kumar Alageshan +6
We present a comparative study of transport in two optimized stellarator configurations: Wendelstein 7-X (W7-X) and a recent design called Quasi-Symmetric Turbulence Konzept (QSTK)…
Neural network assisted electrostatic global gyrokinetic toroidal code using cylindrical coordinates
Jaya Kumar Alageshan, Joydeep Das, Tajinder Singh +2
Gyrokinetic simulation codes are used to understand the microturbulence in the linear and nonlinear regimes of the tokamak and stellarator core. The codes that use flux coordinates…
Kinetic particle simulations in a global toroidal geometry
S. De, T. Singh, A. Kuley +5
The gyrokinetic toroidal code (GTC) has been upgraded for global simulations by coupling the core and scrape-off layer (SOL) regions across the separatrix with field-aligned partic…
