Laser–electron beam collisions that aim to generate electron–positron pairs require laser intensities I ≳ 1021 W cm−2, which can be obtained by focusing a 1-PW optical laser to a spot smaller than 10 μm. Spatial synchronization is a challenge because of the Poynting instability that can be a concern both for the interacting electron beam (if laser-generated) and the scattering laser. One strategy to overcome this problem is to use an electron beam coming from an accelerator (e.g., the planned E… Expand

Signature of Collective Plasma Effects in Beam-Driven QED Cascades.
TLDR
Signatures of collective pair plasma effects in QED cascades are shown to appear, in exquisite detail, through plasma-induced frequency upshifts in the laser spectrum, which can be detected even in small plasma volumes moving at relativistic speeds. Expand
