Such monitor is useful for accelerator commissioning and beam alignment, and allows real-time monitoring of e⁻e⁺ beam loss position and intensity. Single optical fiber (OF) section can cover the entire accelerator instead of using a large number of local beam loss monitors. In this paper brief OFBLM selection in comparison with other distributed loss monitors was given. Methods to improve monitor spatial resolution are discussed. By selecting 45 m long silica fiber (with a large core of 550 um) and microchannel plate photomultiplier (MCP-PMT), less than 1 m spatial resolution can be achieved.
