Particle Acceleration 2

[HEDS8-01(Invited)] Theoretical modelling of ion acceleration by kJ petawatt lasers with long-pulse and large-spot effects

*Natsumi Iwata¹ (1. Institute of Laser Engineering, Osaka University)

We present a model to describe enhanced ion acceleration by kJ petawatt lasers. We derive the condition that the sheath acceleration field strength is maintained constant without depletion owing to the long-pulse and large-spot effects.
