Nonlinear saturation of magnetic curvature driven Rayleigh Taylor instability in three dimensions
Abhijit Sen, Amita Das, Predhiman Kaw +2
We present three dimensional fluid simulation results on the temporal evolution and nonlinear saturation of the magnetic curvature driven Rayleigh-Taylor (RT) instability. The mode…
Laser Generated Magnetic Pulses: Hot Electron Propagation in Conducting and Dielectric Material
A. S. Sandhu, S. Sengupta, A. Das +3
We report experimental evidence of electrostatic inhibition of fast electrons, generated in a highly resistive material upon irradiation with an intense ultra-short ($10^{16} W/cm^…
Study of Coherent and Incoherent Plasma Emissions: Role of Plasma Wave Excitation and Breaking
Arvinder S. Sandhu, G. Ravindra Kumar, S. Sengupta +2
Here we experimentally map the dynamics of electron plasma waves in laser solid interaction. We do time resolved measurements of second harmonic and hard X-ray generation from inte…
Evidence of Levy stable process in tokamak edge turbulence
R. Jha, P. K. Kaw, D. R. Kulkarni +2
In an effort to understand the fundamental physics of turbulent transport of particles and heat in a tokamak, the floating potential fluctuations in the the scrape-off layer plasma…
