Plasma photonic spatiotemporal synchronization of relativistic electron and laser beams
Plasma photonic spatiotemporal synchronization of relativistic electron and laser beams
We present an ultracompact plasma-based method to measure spatial and temporal concurrence of intense electron and laser beams nonintrusively at their interaction point. The electron beam couples with a laser-generated seed plasma in dependence of spatiotemporal overlap, which triggers additional plasma production and manifests as enhanced plasma afterglow. This optical …
