“…At the Institute of Heavy Ion Physics, Peking University CLAPA (Compact LAser-Plasma Accelerator) is a dedicated facility for laser-driven plasma accelerator experiments; it includes a 5 J, 25 fs, 5 Hz, 200 TW commercial Ti:sapphire laser supplied by Thales, a plasma accelerator, proton beam transport line and the application platform [138] . The XPW technique is used in the system, allowing nanosecond contrasts of , and the picosecond contrast can reach 20 ps in front of the pulse.…”

In the 2015 review paper ‘Petawatt Class Lasers Worldwide’ a comprehensive overview of the current status of high-power facilities of ${>}200~\text{TW}$ was presented. This was largely based on facility specifications, with some description of their uses, for instance in fundamental ultra-high-intensity interactions, secondary source generation, and inertial confinement fusion (ICF). With the 2018 Nobel Prize in Physics being awarded to Professors Donna Strickland and Gerard Mourou for the development of the technique of chirped pulse amplification (CPA), which made these lasers possible, we celebrate by providing a comprehensive update of the current status of ultra-high-power lasers and demonstrate how the technology has developed. We are now in the era of multi-petawatt facilities coming online, with 100 PW lasers being proposed and even under construction. In addition to this there is a pull towards development of industrial and multi-disciplinary applications, which demands much higher repetition rates, delivering high-average powers with higher efficiencies and the use of alternative wavelengths: mid-IR facilities. So apart from a comprehensive update of the current global status, we want to look at what technologies are to be deployed to get to these new regimes, and some of the critical issues facing their development.

A Compact laser plasma accelerator (CLAPA) is being built in Peking University, which is based on RPA-PSA mechanism or other acceleration mechanisms. According to the beam parameters from preparatory experiments and theoretical simulations, the beam line is preliminarily designed. The beam line is mainly constituted by common transport elements to deliver proton beam with the energy of 1~50MeV, energy spread of 0~±1% and current of 0~10 8 proton per pulse to satisfy the requirement of different experiments. The simulation result of 15MeV proton beam with an energy spread of ±1%, current of 1×10 8 proton per pulse and final spot radius of 9mm is presented in this paper.
