论文摘要
我们对TEV尺度PWFA（粒子驱动的等离子体Wakefield加速度）进行梁梁参数研究$ \ MATHRM {e}^+$$ \ $ \ MATHRM {e}^ - $使用豚鼠模拟的线性碰撞器。研究表明，总的发光度遵循$ 1/\ sqrt {σ_z} $ - 由Beamstrahlung理论预测的缩放，其中$σ_z$是RMS束长度，这对PWFA是有利的，因为短束长度是首选。我们还为3 TEV PWFA线性对撞机提供了一个参数集，其主梁参数优化了Beamstrahlung引入的光度和光度扩散。 最后，该研究还比较了场景的性能，即带有CLIC参数在3 TEV和14 TEV处的正电子束电荷降低。
We perform a beam-beam parameter study for a TeV-scale PWFA (particle-driven plasma wakefield acceleration) $\mathrm{e}^+$$\mathrm{e}^-$ linear collider using GUINEA-PIG simulations. The study shows that the total luminosity follows the $1/\sqrt{σ_z}$-scaling predicted by beamstrahlung theory, where $σ_z$ is the rms beam length, which is advantageous for PWFA, as short beam lengths are preferred. We also derive a parameter set for a 3 TeV PWFA linear collider with main beam parameters optimised for luminosity and luminosity spread introduced by beamstrahlung. Lastly, the study also compare the performance for scenarios with reduced positron beam charge at 3 TeV and 14 TeV with CLIC parameters.
