A current pulse with an amplitude of 500A and duration of 10 mu s has created the discharge in the tube. Instantaneous electron densities are estimated from the interference pattern in Mach-Zehnder interferometer using femtosecond Ti: sapphire laser beam. Laboratory results are compared with results of computer modelling by MHD computer codes NPINCH and ZSTAR. Time development of the discharge resistance according to experiment is measured and evaluated. Minimum measurable value of the electron density in the experiment is determined as 2x1015cm-3.
