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…
Experimental observation of drift acoustic cnoidal waves in a magnetized plasma
Tanmay Karmakar, Rosh Roy, Lavkesh Lachhvani +5
We report the experimental observation of highly nonlinear coherent structures in a linear magnettized plasma characterized by a strong background density gradient and significant…
Shock wave bending around a dusty plasma void
Sachin Sharma, Rauoof Wani, Prabhakar Srivastav +4
We report on experimental observations of the bending of a dust acoustic shock wave around a dust void region. This phenomenon occurs as a planar shock wavefront encounters a compr…
The CHIMERAS Project: Design Framework for the Collisionless HIgh-beta Magnetized Experiment Researching Astrophysical Systems
S. Dorfman, S. Bose, E. Lichko +11
From the near-Earth solar wind to the intracluster medium of galaxy clusters, collisionless, high-beta, magnetized plasmas pervade our universe. Energy and momentum transport from…
