Laser wakefield accelerators?(LWFAs) are?considered to be?one of the most competitive?nextgeneration?accelerator?candidates. In this paper, we will study the potential high-flux electron beam production?of an LWFA driven by petawatt-level laser pulses. In our three-dimensional particle-in-cell simulations, an optimal set of parameters gives ~40 n C of charge with 2 PW laser power, thus ~400 k A of instantaneous current if we assume the electron beam duration is100 fs. This high flux and its secondary radiation are widely applicable in nuclear and QED physics, industrial imaging, medical and biological studies.
