论文摘要
在本文中，通过模拟实验证明了基于等离子体加速器的电子峰撞机的可行性。从SPS提供的17.612cm质子束开始，模拟表明，长质子束可以在均匀的等离子体中的长质子束的上半部分中通过播种自调节形成几个高质量的质子束。然后，我们使用这些高质量的束将韦克菲尔德（Wakefield）刺激，并加速证人正电子和见证电子。仿真结果表明，大约90米加速后证人束的平均能量约为125 GEV，平均加速度梯度约为1.3 GEV/m。正电子 - 电子碰撞的质量（COM）能量约为125 GEV。还讨论了能量传播，证人粒子的存活率，输出证人束的发射率和发光性。
In this paper, the feasibility of the electron-positron collider based on plasma accelerator is proved by simulation experiments. Starting from the 17.612cm proton beam provided by SPS (super proton synchrotron), the simulation shows that the long proton beam can form several high quality proton bunches through seeded self-modulation in the first half of the long proton beam in a uniform plasma. Then we use these high-quality bunches to excite the wakefield in a uniform plasma and accelerate witness positrons and witness electrons. The simulation results show that the average energy of witness bunches after about 90 meters acceleration is about 125 GeV, and the average acceleration gradient is about 1.3 GeV/m. The center-of-mass (CoM) energy of positron-electron collision is about 125 GeV. The energy spread, witness particle survival rate, emittances and luminorsity of the output witness bunches are also discussed.
