Kinetic simulations of collision-less plasmas in open magnetic geometries
Atul Kumar, J. F. Caneses Marin
Laboratory plasmas in open magnetic geometries can be found in many different applications such as (1) Scrape-Of-Layer (SOL) and divertor regions in toroidal confinement fusion dev…
Precursor magneto-sonic solitons in a plasma from a moving charged object
Atul Kumar, Abhijit Sen
The nature of fore-wake excitations created by a charged object moving in a magnetized plasma is investigated using particle-in-cell simulations. Our studies establish for the firs…
A new mechanism of direct coupling of laser energy to ions
Ayushi Vashistha, Devshree Mandal, Atul Kumar +2
The well-known schemes (e.g. Brunel, resonance absorption, JxB heating etc.) couple laser energy to the lighter electron species of the plasma. In this work, a fundamentally new me…
Drift waves with dust acoustic wave coupling
Atul Kumar, Amita Das, Predhiman Kaw
Drift wave is a prominent mode of a magnetized plasma of inhomogeneous density. It plays an important role in the transport of particles, energy and momentum perpendicular to the a…
Excitation of KdV Alfven solitons by a pulsed CO2 laser in plasma in the presence of an external magnetic field
Atul Kumar, Chandrasekhar Shukla, Deepa Verma +2
The interaction of laser with plasmas leads to many interesting phenomena which includes laser energy absorption, mode conversion, energetic particle generation etc. In this work,…
Fast Ignition Laser Fusion Using In-Situ Ion Acceleration With Pulsed CO2 Lasers
Atul Kumar, Chandrasekhar Shukla, Predhiman Kaw +1
Fast ignition is an alternative concept of laser fusion in which the task of compressing the fusion pellet to supersolid densities is accomplished by the conventional high energy n…
