中文摘要: |
为了突破传统加速器的能量限制,科学家提出三种基于等离子体尾场的加速器:激光驱动等离子体加速器、电子束驱动等离子体加速器和质子束驱动等离子体加速器。与传统加速器相比,由激光或束流驱动激发的等离子体尾场具有承载极高加速场强的能力,通过理论分析、仿真模拟和实验研究证明这三种基于等离子体尾场的加速器具有在短距离内将带电粒子加速到GeV甚至TeV能量级别的潜力,因此可以用于设计新型TeV能量级别的正负电子对撞机和强子-轻子对撞机。本篇论文采用文献综述的方式,从等离子体尾场加速原理出发,概述和比较三种加速器的原理、进展和优缺点,根据国际上现有研究设备设计新型对撞机,并分析对撞能量和亮度。

外文摘要: |
In order to break through the energy limitation of traditional Radio Frequency accelerators, scientists have brought up with three types of new acceleration method based on plasma wakefield: Laser-driven plasma-wakefield accelerator, Electron-driven plasma wakefield accelerator and Proton-driven plasma wakefield accelerator. As a basic property of plasma, the wakefields excited by laser or particle beams can support extremely large electric field. Hence, according to the principle analysis, simulation and experiments, the great potential has been proved that these plasma accelerators can accelerator charged particles to GeV or TeV energy frontiers in short distances. Therefore, these three plasma accelerators may be applied to the design and build of electron/positron colliders or hadron/lepton colliders. In this paper, the physics, achievements, pro and cons of the three plasma wakefield-based accelerators are discussed and compared. Besides, using the parameters in ILC, LHC, SPS, the designs and analysis of electron/positron collider and electron/proton collider are shown, with the calculations in colliding energies and luminosity.
