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…
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…
Evidence of new finite beam plasma instability for magnetic field generation
Amita Das, Atul Kumar, Chandrasekhar Shukla +8
We demonstrate by computer simulations, laser plasma experiments, and analytic theory that a hitherto unknown instability is excited in the beam plasma system with finite transvers…
Ion Vortex Beam
Chandrasekhar Shukla, Amita Das
Recent advances in intense short pulse laser interaction with thin foil enable us to accelerates the ions upto relativistic velocity in a controlled way. The accelerated ion beams…
Merger and reconnection of Weibel separated relativistic electron beam
Chandrasekhar Shukla, Atul Kumar, Amita Das +1
The relativistic electron beam (REB) propagation in a plasma is fraught with beam plasma instabilities. The prominent amongst them being the collisionless Weibel destabilization wh…
