Abstract

High-repetition rate target development for proton acceleration by laser-plasma experiments is of great importance for future multidisciplinary applications, as envisioned at the ELIMAIA user beamline. The use of gas-jet based target, capable of high-repetition rate (10Hz and beyond) and typically used to generate under-critical density plasma, can overcome such problematic using a gas-mixture. We report on acceleration of protons from an under-critical plasma in a gas-jet-mixture capable of high-rep.-rate using a 4.3-J, 27-fs laser beam system. The interaction has been optimized using a deformable mirror prototype as envisioned in the ELIMAIA beamline to improve the flexibility in user experiments.
