Validation of MHD Code FLUX-rz Using Scintillation Measurements of Thermal Radiation in Nested Wire Array $Z$ -Pinch

This paper demonstrates the improved simulation of a Z-pinch experiment with 2-D magnetohydrodynamic code FLUX-rz developed in RFNC-VNIIEF. A Z-pinch load was nested wire array powered by a helical magnetocumulative generator with the current pulse
$I_{\max } \approx 4.2$
MA and effective rise time
$\tau \approx 400$
ns. Validation of X-ray spectral measurements carried out with scintillation detector filters pointed out a necessity to take into consideration both the scintillator “dead” layer and oxide films on the aluminum filter surface.
