Heavy-ion dynamics in the acceleration of protons by the interaction of high-power lasers with double-layer targets
Quantum Electronics and Laser Science Conference (QELS). 2005 ;3 :1822-1824
Back to previous list
The dynamics of heavy-ions during the laser acceleration of protons is theoretically studied by means of 2D particle-in-cell simulations and a 1D analytical hydrodynamic model. The heavy-ion motion is found to modify the longitudinal electric field distribution, thus changing the acceleration conditions for the protons. © 2005 Optical Society of America.
