In preparation for a demonstration of optical stochastic cooling in Cornell Electron Storage Ring, we have developed a particle tracking simulation to study the relevant beam dynamics. Optical radiation emitted in the pickup undulator gives a momentum kick to that same particle in the kicker undulator. The optics of the electron bypass from pickup to kicker couples betatron amplitude and momentum offset to path length so that the momentum kick reduces emittance and momentum spread. Nearby electrons contribute an incoherent noise. Layout of the bypass line is presented that accommodates optics with a range of transverse and longitudinal cooling parameters. The simulation is used to determine cooling rates and their dependence on bunch and lattice parameters for bypass optics with distinct emittance and momentum acceptance.

康奈尔电子存储环中传输时间光学随机冷却过程的模拟

为了准备在康奈尔电子存储环中演示光学随机冷却，我们开发了粒子跟踪模拟来研究相关的光束动力学。拾取波荡器中发射的光辐射对喷射波荡器中的同一粒子产生动量冲击。电子从拾音器到喷射器的光学器件将电子加速器振幅和动量偏移与路径长度耦合，从而使动量喷射降低了发射率和动量扩散。附近的电子会产生非相干噪声。旁路管线的布局可容纳具有一系列横向和纵向冷却参数的光学器件。该模拟用于确定冷却速率及其对具有不同发射率和动量接受度的旁路光学器件的束和晶格参数的依赖性。
