Modelování pinčujícího kapilárního výboje v dusíku pro rekombinační x-laser
Vrba, Pavel ; Vrbová, M.
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.
