Single wire exploding experiments on fast linear transformer driver

Experiments about single wire exploding were carried out on the fast linear transformer driver (FLTD), which provides a current of about 100 ns rising time and about 100 kA maximum amplitude. Laser probe and visible framing camera have been set up for plasma diagnostics. In addition, visible detector PIN and XRD were used to measure the characteristic of radiation for single wire exploding. A series of images for single tungsten wire (15 μm W) and coated tungsten wire (15 μm W+2 μm Polyimide) exploding experiments have been obtained, which show the evolution of wire ablating and the instability development of ablated plasma. The results show that wire coating will add more energy to the wire at the initial phase, hence improve the characteristics of wire exploding.
