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)…
