“…For the unlimited beam rise it took more than 10 ns to obtain the pressure driven currents and the confinement, while the plasma radius was more than doubled. In recent experiments an anomalous resistivity was obtained ( SETHIAN et al, 1984), which may point to much higher resistivities, even 100 times the Spitzer resistivity. At such resistivities the beam should reduce the expansion very strongly.…”

“…RECENTLY, THE INTEREST in Z-pinches has grown due to successful research on equilibrium pinches (HAINES, 1982;HAINES et al, 1984;HAMMEL et al, 1983;HAMMEL and SCUDDER, 1987;SETHIAN et al, 1984SETHIAN et al, , 1987. Discharges in these experiments have had a prolonged stable period up to 100 ns in contrast to the early experiments of compression pinches where the discharges were quickly disrupted.…”

Weak radial expansion of a Z-pinch plasma column during its strong initial ohmic heating phase is expected when the generation of a confining magnetic field is assisted by a correctly formed electron beam pulse. Appropriate one-dimensional magnetohydrodynamic equations are numerically solved, and the observed increase of plasma radius as a function of time for various discharge parameters is compared to a normal Z-pinch discharge initiation.
