概述了一个10 GeV的激光等离子体加速器（LPA）的设计，将由PW级激光系统和BELLA项目，其主要目标是建立和安装所需的钛：蓝宝石激光系统的加速实验驱动。10 GeV级的基本设计目标是在准线性状态下运行，其中激光激发的尾流主要是正弦曲线，并提供了加速电子和正电子的可能性。模拟结果表明，在米级等离子体通道引导的LPA中可以产生10 GeV的电子束，该LPA以约1017 cm-3的密度工作，并且由在50- 200 fs持续时间脉冲中包含30-40 J能量的激光脉冲供电，聚焦到50-100微米的斑点尺寸。将介绍该设施和激光系统的布局以及建设该设施的进展情况。
An overview is presented of the design of a 10 GeV laser plasma accelerator (LPA) that will be driven by a PW-class laser system and of the BELLA Project, which has as its primary goal to build and install the required Ti:sapphire laser system for the acceleration experiments. The basic design of the 10 GeV stage aims at operation in the quasi-linear regime, where the laser excited wakes are largely sinusoidal and offer the possibility of accelerating both electrons and positrons. Simulations show that a 10 GeV electron beam can be generated in a meter scale plasma channel guided LPA operating at a density of about 1017 cm-3 and powered by laser pulses containing 30-40 J of energy in a 50- 200 fs duration pulse, focused to a spotsize of 50-100 micron. The lay-out of the facility and laser system will be presented as well as the progress on building the facility.
