主　　题：hydrodynamic simulations ion acceleration laser–plasma interaction 

摘      要：We study the optimization of collisionless shock acceleration of ions based on hydrodynamic modelling and simulations of collisional shock waves in gaseous *** models correspond to the specifications required for experiments with the CO2 laser at the Accelerator Test Facility at Brookhaven National Laboratory and the Vulcan Petawatt system at Rutherford Appleton *** both cases,a laser prepulse is simulated to interact with hydrogen gas jet *** is demonstrated that by controlling the pulse energy,the deposition position and the backing pressure,a blast wave suitable for generating nearly monoenergetic ion beams can be *** on the energy absorbed and the deposition position,an optimal temporal window can be determined for the acceleration considering both the necessary overdense state of plasma and the required short scale lengths for monoenergetic ion beam production.
