Efficient laser acceleration of deuteron ions through optimization of pre-plasma formation for neutron source development Open
With the objective to develop a compact neutron source with laser accelerated ions, optimization of pre-formed plasmas for efficient target normal sheath acceleration (TNSA) of deuteron ions is investigated using two-dimensional radiation …

Pulse Width Evaluation of Laser-Driven Neutron Source Open
We numerically evaluated the pulse width of a laser-driven neutron source for electron- and protondriven pitcher-catcher schemes with a light water moderator. Particle-in-cell simulations were conducted to simulate laser irradiation on the…

An optimum design of implosion with external magnetic field for electron beam guiding in fast ignition Open
Compression of solid spherical target under the strong external magnetic field is studied using two dimensional radiative magneto-hydrodynamic (MHD) simulation code for fast ignition. The simulation results show that a compression of a sol…
