Abstract

The invention discloses a multistage gas target system suitable for 10GeV electron acceleration. The system comprises a plurality of gas target units, an interstage connecting device, a gas target adjusting device and the like. According to the invention, a multi-stage gas target scheme with three or more stages is provided for the first time, the length and the longitudinal density distribution curve of the gas target are effectively regulated and controlled, long-distance acceleration of the electron beam is realized, and the energy of the electron beam is increased to 10GeV or more. The invention provides a feasible gas target implementation scheme for breaking through 10GeV energy challenge in laser-driven tail field acceleration research, and the gas target implementation scheme can be technically realized through a multi-stage gas box or a capillary tube.

Description

technical field [0001] The invention relates to the research field of the interaction between femtosecond relativistic ultra-intensive laser pulses and plasma, specifically, it is a gas target system suitable for ultra-high-energy electron acceleration. Background technique [0002] The rapid development of the field of laser-driven electron acceleration research depends on the rapid improvement of femtosecond laser technology. So far, the world's multiple petawatts (PW, 10 15 Watts) laser devices are running stably, and 10PW laser devices have also been built one after another, gradually entering the stage of physical experiments. Especially in China, several 10PW femtosecond laser devices and one 100PW femtosecond laser device will be built within a few years. As the laser pulse output power becomes higher and higher, it will bring new developments in the field of compact particle acceleration. Electron acceleration driven by ultra-strong femtosecond laser pulses can ob...
