Abstract Matter-antimatter plasmas, such as electron-positron pair plasmas, are frequently observed in various astrophysical phenomena. In laboratory settings, electron-positron pairs have often been generated using high-Z converters irradiated by ei

We examined electron–positron pair production in solid iron, zinc, tungsten, and lead targets irradiated by a laser-accelerated electron beam generated with a 100 TW laser. These targets were assessed at the target thickness of 0.5, 1.25, and 2.0 r

Abstract The characterization of an electron–positron beam generated from the interaction of a multi-GeV electron beam with a lead plate is performed using GEANT4 simulations. The dependence of the positron beam size on driver electron beam energy

The proliferation of country and state-level net zero-emission commitments, rising energy costs, and the quest for energy security in the wake of the Ukraine crisis have renewed the debate about the future of energy sources. As opposed to elite disco

Decarbonization policies are being stymied by political conflict. Local communities might oppose decarbonization infrastructure such as solar farms, mines, or transmission lines if they view these projects as imposing high costs on them in relation t

Linux is becoming the de-facto standard operating system for today’s high-performance computing (HPC) systems because it can satisfy the demands of many HPC systems for rich operating system (OS) features. However, owing to features intended for th

We present a scaling law ( $Y\sim {E^\beta }$ ) of fusion neutron yields ( Y ) for laser pulse energy ( E ) in laser-cluster fusion experiments. We compare the available neutron yield data from previous deuterium cluster fusion experiments with those
