Studies of the hard X-ray emission from the Filippov type plasma focus device, Dena

This article is about the characteristics of the hard X-ray (HXR) emission from the Filippov type plasma focus (PF) device, Dena. The article begins with a brief presentation of Dena, and the mechanism of the HXR production in PF devices. Then using the differential absorption spectrometry, the energy resolved spectrum of the HXR emission from a 37 U discharge in Dena, is estimated. The energy flux density and the energy fluence of this emission have also been calculated to be 1.9 kJ cm(-2) s(-1) and 9.4 x 10(-5) J cm(-2). In the end, after presentation of radiography of sheep bones and calf ribs, the medical application of the PF devices has been discussed.
