论文摘要
我们详细详细介绍了一种分别超过$ 96 \％$和$ 89 \％$的GEV-PHOTON源的方法$ 10^{21} \，\ textrm {photons}/（\ textrm {s}〜\ textrm {mm}^2〜 \ textrm {mrad}^2〜0.1 \％〜\％〜\ textrm {bw}）$。使用当前可用的多GEV电子束和中等相对论强度的激光脉冲，我们展示了弱非线性状态如何产生主要平行于激光场的光子极化。我们通过考虑各种发射率的电子束与线性和圆形圆形激光脉冲在各个角度范围内相撞，从而证明了这种方案的鲁棒性。
We detail a method to produce a GeV-photon source with polarisation purity exceeding $96\%$ and $89\%$ for linear and circular polarisation respectively and with a brilliance of the order of $10^{21}\,\textrm{photons}/(\textrm{s}~\textrm{mm}^2~\textrm{mrad}^2~0.1\%~\textrm{BW})$. Using currently available multi-GeV electron bunches and laser pulses of moderately relativistic intensities, we show how the weakly nonlinear regime can produce photons polarised mainly parallel to the laser field. We demonstrate the robustness of this scheme by considering electron bunches of various emissivities colliding with linearly and circularly-polarised laser pulses at a range of angles.
