文摘The paper discusses a possible energy transformation that leads to the acceleration of fast ions and electrons.In plasma-focus discharges that occur during deuteriumfilling,which have amaximumcurrent of about 1MA,the accelerated deuterons produce fast fusion neutrons and fast electrons hard X-ray emissions.Their total energy,which is of the order of several kilojoules,can be delivered by the discharge through a magnetic dynamo and selforganization to the ordered plasma structures that are formed in a pinch during the several hundreds of nanoseconds of the pinch implosion,stagnation,and evolution of instabilities.This energy is finally released during the decay of the ordered plasma structures in the volume between the anode face and the umbrella front of the plasma and current sheath in the form of induced electric fields that accelerate fast electrons and ions.
