提出了一种基于电弧旁路设计的康奈尔电子储存环（CESR）光学随机冷却（OSC）实验。这种电弧旁路提供了比狗腿式弯道更长的光学延迟，开辟了多程或分级光学放大器的可能性，可以实现强子或重离子有效冷却所需的增益。除了介绍电弧旁路，在本文中，我们研究了包括它的偶极子的稳定性要求，并调查使用的光学反馈系统放松偶极子和光路的稳定性公差。
A proposed experiment to demonstrate optical stochastic cooling (OSC) in the Cornell Electron Storage Ring (CESR) based on an arc-bypass design is presented. This arc bypass provides significantly longer optical delay than the dog-leg style chicane, opening up the possibility of a multipass or staged optical amplifier that can achieve the gains required for effective cooling of hadron or heavy ions. Beyond introducing the arc bypass, in this paper we study the stability requirements for the dipoles comprising it and investigate the use of an optical feedback system to relax the dipole and light-path stability tolerances.
