Title: Shock injector for low-laser energy electron injection in a laser plasma accelerator

Abstract

This disclosure provides systems, methods, and apparatus related to laser plasma accelerators. In one aspect a block of material defines a gas inlet, a chamber in fluid communication with the gas inlet, a throat in fluid communication with the chamber, a channel in fluid communication with the throat, and a gas outlet in fluid communication with the channel. The throat is configured to generate a supersonic flow of a gas when the gas flows through the throat. The channel includes a ramp that is positioned proximate the gas outlet, with the ramp being inclined at an angle with respect to a direction of a flow of the gas proximate a surface of the channel prior to the ramp at the gas outlet.
