Abstract
A series of experiments studying Mo wire X-pinch were carried out on “Yang” facility. This facility generated a peak current of about 520 kA with 80 ns rise time. The X-pinch load was composed of two identical Mo wires with a diameter of 10 μm, 15 μm or 20 μm, crossing at an angle of 32°,45° or 60°. X-ray power meter and X-ray framing camera were utilized to measure the power of the X-ray radiation and take X-ray imaging respectively. The results showed that one or more intense X-ray bursts occured and hot spots emitting X-rays of energy exceeding 3 keV were formed. The smallest hot spot was less than 30 μm in diameter.
