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…
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,…
