A simple, efficient scheme was developed to obtain near-gigaelectronvolt electron beams
with energy spreads of few per-mille level in a single-stage laser wakefield accelerator …

We describe a simple scheme, truncated-channel injection, to inject electrons directly into
the wakefield driven by a high-intensity laser pulse guided in an all-optical plasma channel …

Compact electron accelerators are paramount to next-generation synchrotron light sources
