05 Developing New Imaging Techniques

David A. Hammer, Electrical and Computer Engineering, and colleagues in the Laboratory of Plasma Studies produced high-resolution x-ray images of tiny objects such as fly hairs, and living organisms such as ants. What makes these radiographs unique is their extremely fine resolution. They result from X-pinch imaging in which a powerful electrical current is run through a vacuum containing a pair of crossed wires finer than a human hair. This action causes the wires to explode and form a plasma—a dense gas that is so hot that the atoms in it break down. The plasma is called the X-pinch. This new imaging technique could have important applications for medicine or biology. The radiographs also help determine the size of the X-pinch plasma, which is estimated to be less than a thousandth of an inch.
