This paper presents the count rate enhancement observed across Canada's Fixed Point Surveillance network during the solar event on 20 January 2005 and explores the feasibility and value of applying the Fixed Point Surveillance network's long-term and continuous observations for space weather monitoring. The count rate, recorded in the high-energy channel of RS250 sodium iodide detectors, reflects the detector's response to muonic and electromagnetic components of the cosmic ray shower. During the event peak time, simultaneous count rate increases have been observed across many Fixed Point Surveillance network stations at enhancements varying from 10% to 18%, 12- to 15-fold less than relative increases in neutron detector observations.
本文介绍了 2005 年 1 月 20 日太阳活动期间加拿大固定点监测网络观测到的计数率增强，并探讨了应用固定点监测网络的长期连续观测进行空间天气监测的可行性和价值。在高能通道中，RS250 碘化钠探测器记录的计数率反映了探测器对宇宙射线簇射的μ子和电磁分量的响应。在事件高峰期，许多固定点监测网络站同时观察到计数率增强，增强幅度从 10%到 18%不等，比中子探测器观测到的相对增强少 12-15 倍。
