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. <a href="http://library.psfc.mit.edu/catalog/reports/2020/21ja/21ja052/abstract.php">PSFC REPORT PSFC/JA-21-52</a><br /><br />The authors would also like to thank Alex Haid at General Atomics for his work in assembling the targets used in this experiment under NNSA Contract No. DE-NA0001808.
