Optical and electrical diagnostic of underwater Zn-wire explosion

Study of hot dense plasma is very attractive from a few reasons. E.g. it is a source of EUV/soft X-ray radiation. Moreover, if one dimension of this plasma is significantly larger than the other two, and if this shape is quasi-stable, it can even amplify its spontaneous emission, which may result in EUV/soft X-ray lasing. Such elongated plasma can be easily (but expensively) generated by powerful linearly-focused visible/infrared lasers1. In comparison with that discharge plasma sources are much cheaper, but they deliver the required energy into plasma during longer time and, therefore, have very often problems with “stability”. That's why pinching discharges are usually closed in capillaries and this “proximity-wall stabilization” turns to be very efficient. However, for amplification of shorter wavelengths (below 25 nm) the discharge has to burn in metal vapors, which are difficult to feed into a capillary. As a solution we have suggested wire explosion in liquid2, at which a capillary with liquid wall is created.
