Název v původním jazyce

Investigation of X-Ray self-emission of plasma of targets heated by high-power pulses of soft X-Ray radiation

Popis výsledku v původním jazyce

Experiments aimed at investigation of X-ray self-emission of plasma of heated targets consisting of layers of different materials (Mylar, polypropylene, In, Sn, and Au) exposed to the action of energy flux of X-ray radiation (the so-called energy exposure of the target) of up to 10 kJ/cm(2) were carried out. A Z-pinch induced by implosion of a tungsten wire-array by current of up to 4 MA in Angara-5-1 facility was used as a source of high-power X-ray radiation. The temporal dynamics of intensity of self-emission of heated targets was studied. In the process, contribution of expanding layer of a material with high atomic number Z to self-emission of the target dominates that of a Mylar film with effective charge Z(eff) approximate to 4.5. It is demonstrated that the 1/e decay time of target emission depends on expansion dynamics of target plasma.
