Flare and CME activity in the solar corona is often associated with the in-situ detection of solar energetic particles (SEPs). However, the exact mechanism by which flares and/or CMEs produce SEPs is still subject to much debate. In this study, we analyse the coronal activity associated with multiple SEP events from the SEPserver catalogue. This involves observations of EUV waves using the Atmospheric Imaging Assembly (AIA), giving estimates of wave/shock kinematics. We combine this with a detailed investigation of the particle acceleration and shock activity using existing and new spectrographs (e.g., Orfées, Nançay) and the Nançay Radioheliograph. Added to this will be a detailed analysis of CME kinematics and energetics using both the SOHO and STEREO coronagraphs. We have so far compiled a list of ~50 events from the AIA era and created an online catalogue known as ELEVATE. This catalogue will aid the understanding of the coronal conditions that lead to the acceleration of energetic particles.
