The high density $\gamma$-ray emission and dense positron production via multi-lasers driven circular target

Ya-Juan Hou, Bai-Song Xie, Chong Lv +5

A diamond-like carbon circular target is proposed to improve the $\gamma$-ray emission and pair production with lasers intensity of $8\times 10^{22}W/c{\mathrm{m}}^2$ by using two-dimen…
