Abstract

Particle-in-cell simulation is carried out for the expansion of a multi-charged dense plasma for X-ray laser systems. All Coulomb collisions among charged particles are taken into consideration. The rapid cooling of the multi-charged plasma, which is essential for X-ray lasing, is accomplished when this plasma is surrounded by a cold ambient plasma. The mechanism of this cooling is clarified by the simulation. The expansion spreads, accompanying with the expanding dense wave front. Existence of a double layer of electric charge at the wave front is confirmed.
