The Sun via its activity disturbs the heliosphere and affects the Earth. The Sun is unique by its proximity and hence accessibility for detailed studies of the non-thermal processes of particle acceleration, transport and escape into interplanetary space. In addition, understanding of the non-thermal particles is one of the key elements of Sun-Earth connection studies and as such an important element of Space Weather. Non-thermal electrons and hot plasma can normally be studied using X-ray and UV emission. However, higher in the corona, the plasma is too dilute to use either X-ray or UV emission, so only radio emission can be used to study the non-thermal processes at these heights. Over the last two years, we obtained a unique set of observations with unprecedented temporal and frequency resolutions using the Low Frequency Array (LOFAR). The new observations at sub-second scales require new models and a re-thinking of the current understanding of the non-thermal processes in the outer corona. In the view of the unprecedented radio data, we plan to complement these radio observations with the data from a suite of spacecrafts (RHESSI, SOHO, STEREO, SDO, Fermi) to gain a new level of understanding of the non-thermal processes in the outer corona. This is a particularly timely activity which can help to better plan future observations with the Square Kilometre Array and the future space missions Solar Orbiter and Solar Probe Plus. The team consists of active research scientists with diverse approaches and expertise, but as a team covering all necessary aspects the key experience in non-thermal processes in the corona.
