  1. 1. A new model and tests of the JEM-EUSO Balloon pathfinders Fresnel optics

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Abraham Neftali Díaz Damián; [2016]
    Keywords : Cosmic Rays; Fresnel Optics; Extensive Air Showers; Instrumentation;

    Abstract : EUSO-Balloon and EUSO-SPB are balloon borne pathfinder projects designed to val- idate the techniques of the JEM-EUSO space observatory. They are nadir pointing UV telescopes that use experimental experimental Fresnel optics to detect the ultravi- olet emission of Extensive Air Showers (EAS) induced by Ultra High Energy Cosmic Rays (UHECR) in the atmosphere.
