Maximum proton energies significantly greater than established scaling laws were observed, consistent with observations at other multi-ps laser facilities. In addition, maximum proton energies and electron temperatures in this regime were found to be strongly dependent on the laser pulse duration and preplasma conditions. A modified proton scaling model is presented that is able to better represent the accelerated proton characteristics in this multi-ps regime.Physicselectron accelerationlaser facilitieslaser intensitieslaser pulse durationlaser-driven electronspicosecond regimeproton accelerationshort-pulse lasersNONE
