Modelling of pinching capillary discharge in Nitrogen for X-ray laser dumping (l‘ Aquila experiment).
Vrba, Pavel; Vrbová, M.
2005 - English Computer simulations reported here were done in the frame of collaboration among Czech Technical University in Prague, Institute of Plasma Physics AS CR and Italian University of l’Aquilla as a preparation of autumn 2005 experiment in l’Aquilla laboratory. Presuming that the current quarter cycle t1 = 87.5 ns is invariant, we have come to the conclusion that a measurable gain factor may achieved only if the peak value of the current Imax is approaching to the value of 43 kA and if it is used a capillary, with diameter 2R0 approximately equal to 6 mm. More efficient laser pumping is expected with a shorter quarter cycle as it was presented in [1]. Validity of our model may be checked even with a thinner capillary currently used and lower values current amplitudes on the basis of comparison of the pinch time delays and spectra measured and calculated. Byly provedeny simulační výpočty společného česko-italského experimentu KE CVUT, UFP AVČR a University v l’Aquille. Za předpokladu, že čtvrt perioda t1 = 87.5 ns proudového pulsu je neměná bylo spočteno, že maximálního zisku lze dosáhnout jestliže hodnota proudu Imax= 43 kA pro kapiláru o průměr 2R0 = 6 mm.Efektivnějšího laserového pumpování lze očekávat pro kratší čvrt periodu. Platnost našeho modelu byla kontrolována pro tenší kapiláry a menší hodnoty proudu, přitom byly porovnávány údobí trvání pinče a emitovaná spektra .
