Radiographic method for measuring the continuum hard X-ray output spectrum of a Plasma Focus device
(Elsevier Science, 2009-12)
A radiographic method is proposed and then applied to infer the continuum part of the hard X-ray spectrum of a 4.7 kJ Plasma Focus from differential absorption measurements on metals. Copper, nickel, titanium and silver ...
Considerations of a high repitition Capillary Discharge operated in nitrogen as a water-window X-ray microscope source
(IEEE, 2009)
The capillary discharge is a very bright radiation source. When operated as a ns discharge at a peak current of order 10 kA and at a high repetition rate of order 200 Hz a very bright source at 13.5 nm is obtained. We ...
Efficient picosecond x-ray pulse generation from plasmas in the radiation dominated regime
(Optical Society of America, 2017-10)
The efficient conversion of optical laser light into bright ultrafast x-ray pulses in laser created plasmas is of high interest for dense plasma physics studies, material science, and other fields. However, the rapid ...
Small Plasma Focus Studied as a Source of Hard X-ray
(Institute of Electrical and Electronics Engineers, 2001-06)
An experimental study on hard X-ray pulses emitted by a small plasma focus is performed, regarding its application to biological radiographs in fast dynamic situations. It is found that the radiation intensity in a single ...
X-ray and plasma dynamics of an intermediate size capillary discharge
(2002)
A small pulsed power generator, 150 kA and 120 ns, is used to form a plasma in a 5-mm diameter alumina ceramic tube. A hollow cathode geometry is used and a preionized plasma is formed in an initial vacuum background by ...
Plasma focus based flash hard X-ray source in the 100 keV region with reproducible spectrum
(Elsevier Science, 2010-10)
A pulsed hard X-ray source with shot to shot reproducible spectrum, based on a 4.7 kJ small-chamber Mather-type plasma focus device, is presented. The hard X-ray output spectrum was measured in a single shot basis by ...
A model of hard X-rays emission from free expanding Plasma-Focus discharges
(IOP Publishing, 2014-05)
A planar-piston model of the hard x-ray production in Plasma-Focus devices is presented. The model applies Von Karman approximations to represent the inner structure of the pinch. The hard x-ray emission is calculated ...
Ion beam measurements in a small plasma focus operating in hydrogen/gas mixtures
(IEEE, 1998)
Dense transient plasmas of high energy density, can be easily produced in a plasma focus device, on a cost effective basis. High energy ion beam emission is one, among several others, of the very interesting transient ...
Dense plasma focus PACO as a hard X-ray emitter: a study on the radiation source
(IOP Publishing, 2014-06)
The radiation in the X-ray range detected outside the vacuum chamber of the dense plasma focus (DPF) PACO, are produced on the anode zone. The zone of emission is studied in a shot-to-shot analysis, using pure deuterium ...
Experimental investigations of hotspots in a low energy plasma focus operating in hydrogen-argon mixtures
(IEEE, 1998)
We present experimental results on the investigation of hotspot formation in PFP-I, a small 3.8 kJ plasma focus device operating in hydrogen-argon mixtures, at pressures from below 0.2 torr upward. A combination of ...
