  1. 21. The Role of Extensive Air Showers in the Inner Heliosphere
    Dr Hugh Hudson (UC Berkeley)

    Showers initiated by high-energy cosmic rays can inject secondary
    particles into interplanetary space. This will happen best if the
    primary particle arrives at an impact parameter such that the column
    mass corresponds to a nuclear interaction length. A tangential
    shower develops at this point in the atmosphere, and it will then
    project early secondary particles of all sorts in the...

  2. 1. Prediction of Solar Energetic Particle Peak Intensity using CME Speed and Direction in Solar Cycles 23 and 24
    Dr Ian Richardson (University of Maryland, College Park and NASA/GSFC)

    From a survey of solar energetic particle events observed by both the STEREO spacecraft and at the Earth in 2009-2012 during solar cycle 24, Richardson et al. (Solar Physics, 289,3059, 2014) obtained a formula relating the SEP peak intensity at 14-24 MeV with the speed of the associated coronal mass ejection and its direction with respect to the observing spacecraft. This suggests that the...

  3. 16. The Solar Origin of High-Energy Solar Energetic Particle Events
    Nariaki Nitta (Lockheed Martin Solar and Astrophysics Laboratory)
    24/04/2018, 14:40

    One of the remaining questions of solar energetic particle (SEP) events is their links to solar regions and eruptions from them. The solar origin is more strongly found in SEPs at high energies including electrons, and during the early phase. We experience SEP events that apparently contradict our expectation on the onset time, the flux of, and rise time to, the (first) peak, and the angular...

  4. 4. The Third class of Solar Energetic Particles
    Roksoon Kim (KASI)
    24/04/2018, 15:00

    In this presentation, we introduce our recent research results about the solar energetic particles (SEPs), including a basic introduction. Particularly, we discuss on the classification of SEPs. The conventional two classes of SEPs are sorted as impulsive events accelerated by reconnection process in the flaring site and gradual events accelerated in the CME-driven shock. However, in the point...
