| 摘要 |
A method for triggering of lightning discharge which is high in lightning triggering efficiency and capable of surely triggering lightning discharge is provided. The method comprises collimating muons emitted from a high energy proton or electron accelerator, and irradiating the collimated muon beam toward a thundercloud to thereby promote ionization of air in the thundercloud and trigger lightning discharge. An apparatus for implementing the method for triggering of lightning is also provided. The apparatus comprises a high energy proton or electron accelerator from which a proton beam or an electron beam is emitted, a target from which pions are emitted by irradiating the target with the proton or electron beam, a collimator for collimating muons generated by the decay of the pions, and an accelerating tube for accelerating the collimated muon beam and irradiating the muon beam toward a thundercloud.
