Where and how flares efficiently accelerate charged particles remains an unresolved question. Recent studies revealed that a \"magnetic bottle\" structure, which forms near the bottom of a large-scale reconnection current sheet above the flare …
A number of double coronal X-ray sources have been observed during solar flares by RHESSI, where the two sources reside at different sides of the inferred reconnection site. However, where and how these X-ray-emitting electrons are accelerated …
