基于等离子体加速器的高能前沿TeV对撞机由于近年来在多级激光加速方面的成就以及电子和质子驱动等离子体加速器的显著进展而备受关注。这种对撞机可能会由于辐射反应（RR）效应而遭受基本能量损失，因为电子通过电子感应加速器辐射发射而损失能量。虽然RR可能不是低能量加速器的关键，但它将对需要考虑的TeV级等离子体对撞机施加限制。在本文中，我们已经提供了一个广泛的研究RR效应在所有的路径走向这样的对撞机，包括多级等离子体加速驱动的国家的最先进的激光和相对论电子束，以及单级等离子体加速与高能质子束可在欧洲核子研究中心加速器复杂。采用单粒子朗道-利夫希茨方法研究了等离子体吹出区电子加速的RR效应。该模型确定的边界，RR在这样的对撞机上发挥能量限制的作用。通过数值计算，分析了该模型的能量增益、辐射损失和有效性.
Energy-frontier TeV colliders based on plasma accelerators are attracting much attention due to the recent achievements in multi-stage laser acceleration as well as the remarkable advances in electron- and proton-driven plasma accelerators. Such colliders may suffer a fundamental energy loss due to the radiation reaction (RR) effect, as the electrons lose energy through betatron radiation emission. Although the RR may not be critical for low-energy accelerators, it will exert limitations on TeV-class plasma-based colliders that need to be considered. In this paper, we have provided an extensive study of the RR effect in all pathways toward such colliders, including multi-stage plasma acceleration driven by the state-of-the-art lasers and the relativistic electron beam as well as the single-stage plasma acceleration with the energetic proton beams available at the CERN accelerator complex. A single-particle Landau–Lifschitz approach is used to consider the RR effect on an electron accelerating in the plasma blow-out regime. The model determines the boundaries where RR plays an energy limiting role on such colliders. The energy gain, the radiation loss, and the validity of the model are numerically explored.
