Large-scale-length axial nonuniformities in imploding z pinches have been measured with a time-resolved framing pinhole camera and a filtered x-ray diode. The nonuniform initial conditions of the annular gas column result in a nonsimultaneous stagnation along the pinch axis. By tailoring the initial gas-puff density distribution we have reduced the time interval of stagnation from 10 ns to below 4 ns for a 2-cm-long pinch.

    X-ray pinhole images are formed on microchannel plate striplines to time-resolve Z-pinch emissions. Applications include a study of Z-pinch linearity necessary for x-ray lasers, the evolution of hot spots, and a study of Z-pinch heating mechanisms. In particular, multiple pinholes per strip with...

    The development of a preformed constriction in cylindrical agar-agar loads at currents of up to 3 MA is studied experimentally. The loads 3–5 mm in diameter have a mass density of 0.1g/cm[sup 3] and are filled with different materials. Due to the implosion of the constriction to a minimum...

    It is shown that the development of instabilities in a Z-pinch plasma formed by loading a relatively thick Al wire (an initial diameter of 120μm and a maximum discharge current of 2–3 MA) is slowed down due to the high plasma density in the wire corona. A cylindrically symmetric,...

    A study is made of the method for numerical modeling of pulsed plasma systems by simultaneously solving two-temperature MHD equations and the equations of ionization kinetics. As an example, the method is applied to simulate a relatively slow moderate-density Z-pinch, whose dynamics is well...

    A two-dimensional magnetohydrodynamic code that includes resistivity and viscosity has been used to study the growth of m=0 perturbations of a Z pinch in which the current increases with time. Stability for all wave numbers was found when the product SR was less than about 1000, where S is the...

    Recent experiments on gas-puff Z pinches using various ion mixtures have demonstrated that the plasma shell separates into two distinct annuli which implode concentrically. This phenomenon is quantitatively explained with the use of a semihydrodynamic model in which the electrons are treated as...

    A study of Z boson pair production in e[sup +]e[sup -] annihilation using the OPAL detector at LEP is reported. The ZZ production cross-section is measured, limits on anomalous ZZγ and ZZZ couplings are derived, and constraints on models of low scale quantum gravity in extra spatial...
