NLC光束特性和在IP上具有光束偏移的提取线性能
NLC Beam Properties and Extraction Line Performance with Beam Offset at IP
摘要:
在相互作用点(IP)和提取线中的粒子损失的中断的NLC光束的属性进行了分析,作为在IP的光束到光束的位置和角度偏移的函数。模拟结果表明,中断和波束损失最大时,垂直波束分离在IP是约20倍的均方根垂直波束大小。水平偏移不会增加干扰和光束损失。角偏移导致提取线中的粒子损失,主要是因为束轨道振荡。
英文摘要:
Properties of the disrupted NLC beam at the Interaction Point (IP) and particle loss in the extraction line are analyzed as a function of beam-to-beam position and angular offset at IP. The simulations show that disruption and beam loss maximize when the vertical beam separation at IP is about 20 times the rms vertical beam size. The horizontal offset does not increase the disruption and the beam loss. The angular offsets cause particle loss in the extraction line mainly because of the beam orbit oscillations.
