  Impulsive solar energetic particle (ISEP) events show peculiar elemental
composition, with enhanced 3He and heavy-ion abundances, markedly different
from our solar system composition. Furthermore, the events are characterized by
a wide variety of energy spectral shapes from power laws to rounded spectra
toward the low energies. Solar sources of the events have been firmly
associated with coronal jets. Surprisingly, new observations have shown that
events are often accompanied by so-called extreme-ultraviolet (EUV) coronal
waves - a large-scale phenomenon compared to jets. This paper outlines the
current understanding of the linkage of EUV waves with jets and energetic ions
in ISEP events.
