Abstract

A microcylinder target is proposed for a recombination X-ray laser generation and is investigated by a numerical simulation. The size of the target is of the order of 1 cm in the axial direction and 100 μm in the inner radius. The target has an axial slit of 20 μm wide through which a line-focused laser illuminates the inner wall. The hot plasma produced inside is confined, and a part of this is blown out through the slit. This plasma cools due to the free expansion, so that a gain of a recombination X-ray laser appears outside the microcylinder. When a large enough amount of hot plasma is produced inside, it plays the role of a reserver. Numerical results show that the quasi-cw (continuous wave) gain of Hα line is obtained outside the aluminum microcylinder when the plasma, which has not recombined yet, is supplied continuously.
