Formation of two-dimensional monochromatic images of a laser jet by a spherically bent mica crystal

Two-dimensional x-ray images were obtained for a laser-generated plasma jet as it collided with an obstacle and expanded in a static magnetic field. A mica crystal bent to form a spherical surface of 100 mm radius was used. The images were formed by the radiation representing the resonance and inter-combination lines of the Mg XI ion. A shock-compressed zone formed near the obstacle and the expansion cone of the Mg XI ions became narrower in a transverse magnetic field. The spatial resolution in the plane of the image was better than 100 μm for objects of large linear dimensions (~10 mm).
