研究了钼X箍缩的X射线发射，作为动态压缩实验中高压态的潜在探针。研究了一种300kA，400 ns的新型发电机，它将负载直接耦合到一个低电感电容器和开关组合上。X-夹点负载由4根直径为13μm的交叉钼丝组成，以62°的角度交叉。加载高度为10 mm。在导线交叉点产生的初始X射线爆发，辐射在功率从1到7 mW的软X射线范围(hυ10keV)。时间积分光谱测量表明，较硬的爆发以K-α发射为主，但也存在至少30keV的较低水平的宽带连续谱。初步测试表明，该光源能够驱动劳厄衍射实验，探测未压缩的LiF和铝样品。
X-ray emission from a molybdenum X-pinch has been investigated as a potential probe for the high pressure states made in dynamic compression experiments. Studies were performed on a novel 300 kA, 400 ns generator which coupled the load directly to a low inductance capacitor and switch combination. The X-pinch load consisted of 4 crossed molybdenum wires of 13 μm diameter, crossed at an angle of 62°. The load height was 10 mm. An initial x-ray burst generated at the wire crossing point, radiated in the soft x-ray range (hυ 10 keV) whose power ranged from 1 to 7 MW. Time integrated spectral measurements showed that the harder bursts were dominated by K-alpha emission; though, a lower level, wide band continuum up to at least 30 keV was also present. Initial tests demonstrated that the source was capable of driving Laue diffraction experiments, probing uncompressed samples of LiF and aluminium.
