New Formalism for Modelling Flowing Plasmas in a Magnetic Field
Subhasish Bag, Ashish Ganguli, Vikrant Saxena +2
A new formalism for modelling a flowing plasma in a magnetic field, having potential for application in plasma thrusters, materials processing, space plasmas, etc., is developed. I…
Three Dimensional Effects on Proton Acceleration with Grooved Hydrocarbon Targets
Imran Khan, Mohammad Yasir, Vikrant Saxena
Recently, using two-dimensional particle-in-cell simulations, it has been demonstrated that in laser based proton acceleration with micro-structured targets, a single rectangular g…
On the critical role of the rear wall thickness of a grooved TNSA target
Imran Khan, Vikrant Saxena
The cutoff energy and the divergence of the protons generated by the target normal sheath acceleration mechanism are known to be significantly influenced by micrometer and nanomete…
Nonlinear evolution of a cold non-relativistic electron-ion plasma with an arbitrary initial density profile: A phase mixing perspective
Subhasish Bag, Vikrant Saxena
Using a perturbative approach, an evolution equation for the space charge density, correct up to the third order, is deduced for arbitrary initial density profiles of the electron…
A Comparative Analysis of Relativistic Particle Pushers vis-à-vis Computation Time & Accuracy
Mohammad Yasir, Vikrant Saxena
The performance of relativistic particle pushers has long been a topic of interest in the field of computational plasma physics, particularly from the point of view of the particle…
TNSA based proton acceleration by two oblique laser pulses in the presence of an axial magnetic field
Imran Khan, Vikrant Saxena
A recently proposed strategy to boost the proton/ion cutoff energy in the target normal sheath acceleration scheme employs two obliquely incident laser pulses simultaneously irradi…
Not-so-efficient proton acceleration by an intense laser pulse obliquely incident on a structured target
Imran Khan, Vikrant Saxena
The interaction of an obliquely incident laser pulse with a flat TNSA target is known to enhance the cut-off energy of protons/ions as compared to a normally incident laser pulse,…
Femtosecond phase-transition in hard x-ray excited bismuth
M. Makita, I. Vartiainen, I. Mohacs +19
The evolution of the bismuth crystal structure upon excitation of its A phonon has been intensely studied with short pulse optical lasers. Here we present the first-time obs…
