Role of Magnetic Field in the Redistribution of Turbulence from Large-Scale Structures to Small-Scale Fluctuations
Tanmay Karmakar, Rosh Roy, Lavkesh Lachhvani +5
Magnetized plasmas with equilibrium density gradients support drift-wave turbulence, which is often regulated by self-generated zonal flows. In this work, we experimentally examine…

Transition from Zonal Flows to Streamer like structures and associated edge Fluctuations
Tanmay Karmakar, Rosh Roy, Lavkesh Lachhvani +5
We report experimental observations of a controlled transition from a zonal-flow (ZF) dominated regime to a coexistence regime of ZFs and streamers, and finally to a streamer-domin…

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…
