PROJECT TITLE :
Optimization of a Laser-Based Proton Source and a New Mechanism of Ion Acceleration
The three-D particle-in-cell simulations with the code MANDOR demonstrate effective ion acceleration from the interaction of intense ultrashort linearly polarized laser pulses with both ultrathin solid dense foils and low-density targets when the laser energy ranges from many millijoules to tens of joules. The optimum foil thickness and therefore the corresponding most energy of the accelerated ions for a given energy of the laser pulse were found. Totally different mechanisms of ion acceleration, like target traditional sheath acceleration, directed Coulomb explosion, and ponderomotive acceleration, are concerned. We discuss the transition from one acceleration regime to another when the target thickness and density and the laser pulse intensity change and show that reducing the target density significantly will increase the ion energy. We tend to gift some examples of isotope production as a doable application of multimegaelectronvolt proton beams on the joule scale of a laser.
