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 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 ...
Symbiotic stars in X-rays
(Edp Sciences S A, 2012-11-27)
Until recently, symbiotic binary systems in which a white dwarf accretes from a red giant were thought to be mainly a soft X-ray population. Here we describe the detection with the X-ray Telescope (XRT) on the Swift satellite ...
Influence of silver additions on the aging characteristics of the Cu-10.4at.%Al alloy
(1998-03-27)
The influence of additions of 1.3, 2.5, 3.8, 5.1, and 6.3 at.% Ag on the aging behavior of the Cu-10.4at.%Al alloy was studied using microhardness measurements, scanning electron microscopy (SEM) and energy dispersive X-ray ...
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 ...

Hard X-ray emission from the SNR G337.2+0.1
(Springer, 2007-06)
We report the hard X-ray emission of the SNR candidate G337.2+0.1. The object shows centrally filled and diffuse X-ray emission, which peaks in the hard 3.0−10.0 keV band. A spectral study confirms that the column density ...
