Rationale

The study of particle acceleration and transport is an important topic in Astrophysics, Heliophysics and Space-weather research. On the Sun and in the heliosphere, these particles are the sources of electromagnetic emissions at different wavelengths. Starting from electrons and protons to heavier ions are accelerated during the transient activities of the dynamic Sun. Energetic particle acceleration up to several MeV (electrons) and ions up to GeV have been studied theoretically and some of the results have been explored through experimental observations and modelling. Many of the spacecraft dedicated for solar and heliospheric observations have particle detectors of wide energy range. Also, solar energetic particle (SEP) events are one of the major causes of space weather impact on space-based technological systems. Impulsive SEP events are associated with solar flare reconnection sites while the gradual SEP events are accelerated by coronal mass ejection (CME) driven shocks . Many authors have proposed that the abundance of the ambient seed particles is also a determining factor in the large peak intensity of SEP events. These seed particles are believed to be supplied by flaring material from the preceding flares or coronal material from twin-CMEs. CME-driven shocks primarily accelerate protons and heavier ions, and differential elemental compositions and charge states are produced through different acceleration processes and seed populations. CME-driven shocks, in contrast to flares, have a much larger extent in the interplanetary medium. Gradual SEP events affect the natural and artificial satellites on their way. In addition, the abundance of particles in solar events, solar wind acceleration attracted the scientists recently. Large data base of particles from the sun is available from the space-based instruments like the recently launched spacecraft ADITYA L1. It has to be analysed and studied by solar data scientists. In general, a number of questions are to be discussed with experts in this field and presented to the younger audience (college/university research scholars, post-docs and teachers) from this part of geo-sphere. Hence the symposium on particle acceleration has been planned.
