Summary form only given. As a highly intensive and subnanosecond pulse X-ray point source, X-pinch plasma could find many potential applications. A pulsed power generator (500 kV, 400 kA, 100 ns) was constructed and used as the power source of an X-pinch. The X-pinch load was made of two 25-??m Mo wires. The temporal and spatial X-ray emission from the X-pinch was studied by using diamond photoconducting...
Summary form only given. X-pinch plasma is a point-like source of radiation emitting in a wide spectral range. X-pinches are known to achieve very high density (n > 1021 cm) and temperature (>1 keV) at the same time resulting in energy density, much higher than 105 J/cm3. X-pinch radiation source has been proven to be useful for backlighting diagnostic in the keV range as well. A very compact...
Summary form only given. It is well known that implosions of X-pinches and wire arrays produce the powerful laboratory X-ray sources. X-ray spectroscopy is a very useful tool for diagnostics of X-and Z-pinch plasmas at stagnation while EUV spectroscopy seems to be an appropriate tool of diagnosing the plasma before and after the stagnation. Though X-ray spectra that characterize the stagnating plasmas...
A Faraday rotation diagnostic was applied for the investigation of magnetic fields in plasma of 1-MA wire arrays and X-pinches. Laser-probing diagnostics at the Zebra generator include a four-channel polarointerferometer and a four-frame shadowgraphy. The Faraday rotation diagnostic consists of shadow and Faraday channels, shearing air-wedge interferometer, and an additional schlieren channel. The...
Summary form only given. X-pinch plasma is a good soft X-ray source. It emits intense soft X-rays from a small localized point, which makes it of many potential applications. For the purpose of using X-pinch plasma as X-ray backlighting source, a X-pinch device was designed, installed and tested. A pulsed accelerator was constructed for driving X- pinch plasma. The accelerator consists of a MARX generator,...
Summary form only given. X-pinch plasmas are point-like X-ray sources with potential application for backlighting diagnostic in the keV range. A very compact LC generator (40 kV, 200 kA) has been used for driving X-pinches made of 18-25 mum diameter Cu, Mo and W wires with a current rise time of 200 ns. A series of XRD and silicon p-i-n detectors with various filters were used to study their X-ray...
Summary form only given. Between the output electrodes of a 500 kV/400 kA/100 ns pulsed-power generator, two Al wires each with diameter of 10-100 mum crossing and touching at a single point constitute an "x" shape load. The cross position explodes first and then pinches axially to form so-called X-pinch plasma as current is delivered to the "x" wires. In order to analyze the energy...
Summary form only given. The X-pinch plasma has established itself as an extraordinarily useful tool for studying the dynamics and kinetics of hot, dense plasmas as well as for high resolution imaging. An X-pinch plasma is formed when two or more fine wires, which cross at a point to form an "X," are used as the load of a pulse power machine. When this configuration is exploded to form a...
