Abstract—The principle of operation of a distributed beam-loss monitor based on the Cherenkov radiation in optical fiber is considered. The monitor allows real-time monitoring the distribution of the beam loss along the entire accelerator. The methods for increasing the spatial resolution of the monitor implemented on the e^–e⁺ Injection Complex at the Budker Institute of Nuclear Physics are experimentally studied. For a 15-m-long quartz fiber with a diameter of 550 μm and a microchannel plate-based photomultiplier as a radiation detector, a spatial resolution of 0.5 m is achieved.

基于切伦科夫辐射的光纤中分布式光束损失监测仪空间分辨率的提高方法

摘要—考虑了基于切伦科夫辐射的光纤分布式光束损耗监测器的工作原理。监控器可以实时监控整个加速器的光束损耗分布。通过实验研究了在Budker核物理研究所的e ^- e ⁺注入复合体上实施的提高监测器空间分辨率的方法。对于直径为550μm的15米长的石英纤维和基于微通道板的光电倍增管作为辐射探测器，可以实现0.5 m的空间分辨率。
