未来圆形对撞机上的SLC型$e^{+}e^{-}/γγ$装置
An SLC-type $e^{+}e^{-}/γγ$ facility at a Future Circular Collider
摘要：
有人建议将SLC型设施的弧段放置在未来圆形对撞机（FCC）的隧道内。由直线加速器加速，电子和正电子束将以相反的方向穿过弯曲弧，并以大大超过圆形$e^{+}e^{-}$对撞机所能达到的质心能量进行碰撞。拟议中的SLC型设施将具有与传统的双直线加速器$e^{+}e^{-}$对撞机相同的光度。使用光学自由电子激光器，该设施可以转换为$γγ$对撞机。在拟议的设施超导L波段直线加速器可能会形成一个100 TeV的质子对撞机在FCC隧道注入链的一部分。整个加速剂复合物将作为$e^{+}e^{-}$、$γγ$、$pp$和$ep$相互作用的来源。L波段直线加速器还可用于产生高强度中微子、K介子和μ介子束，用于固定靶实验，以及X射线自由电子激光（XFEL）光子，用于材料科学和医学。
英文摘要：
It is proposed to place the arcs of an SLC-type facility inside the tunnel of a Future Circular Collider (FCC). Accelerated by a linear accelerator (linac), electron and positron beams would traverse the bending arcs in opposite directions and collide at centre-of-mass energies considerably exceeding those attainable at circular $e^{+}e^{-}$ colliders. The proposed SLC-type facility would have the same luminosity as a conventional two-linac $e^{+}e^{-}$ collider. Using an optical free-electron laser, the facility could be converted into a $γγ$ collider. A superconducting L-band linac at the proposed facility may form a part of the injector chain for a 100-TeV proton collider in the FCC tunnel. The whole accelerator complex would serve as a source of $e^{+}e^{-}$, $γγ$, $pp$ and $ep$ interactions. The L-band linac could also be used to produce high-intensity neutrino, kaon and muon beams for fixed-target experiments, as well as X-ray free-electron laser (XFEL) photons for applications in material science and medicine.
