Efficacy of Muon detection for solar flare early warning : PSTP 03-412 CIP / by L. Trichtchenko ... [et al.].: D68-4/128-2013E-PDF

This project is motivated by the need for improved protection of Canadian critical infrastructure from solar disturbances. The feasibility study examines the possibility of using measurements of muons produced by cosmic rays (CR) to provide advanced warning of approaching solar disturbances. A literature review and workshops with invited specialists were an essential part of the work. These identified the need for a Canadian muon detector to fill the coverage gap existing in the current, global network. Two types of tasks were undertaken: theoretical investigations performed by the Lead Department, NRCan of the interaction of cosmic rays with solar disturbances; and review of the existing technology and development of the test detector, done by the Physics Department of Carleton University. The study identified two types of precursors associated with the interaction of CR with solar disturbance. The physics-based transport equation for CR has been analysed and the diffusion model was validated. Two types of technology for building detectors were assessed. This included building a prototype muon telescope and analyzing its data. The detailed design specifications and recommendations (roadmap) for a proto operational system are provided.
