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 ...
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 ...
A HARD AND VARIABLE X-RAY EMISSION FROM THE MASSIVE EMISSION-LINE STAR HD 157832
(IOP PUBLISHING LTD, 2011)
We report the discovery with XMM-Newton of a hard-thermal (T similar to 130 MK) and variable X-ray emission from the Be star HD 157832, a new member of the puzzling class of gamma-Cas-like Be/X-ray systems. Recent optical ...
