The Sheared Flow Stabilized Z-Pinch
The stabilizing effect of a sheared axial flow is investigated in the ZaP Flow Z-pinch experiment at the University of Washington. Long-lived, Z-pinch plasmas are generated that are 100 cm long with a 1 cm radius and exhibit gross stability for many Alfvén transit times. Experimental measurements show a sheared flow profile that is coincident with the quiescent period during which magnetic fluc...
متن کاملEvidence of Flow Stabilization in the ZaP Z Pinch Experiment
The stabilizing effect of an axial flow on the m = 1 kink instability in Z pinches has been studied numerically with a linearized ideal MHD model to reveal that a sheared axial flow stabilizes the kink mode when the shear exceeds a threshold. The sheared flow stabilizing effect is investigated with the flow-through Z pinch experiment, ZaP. An azimuthal array of surface mounted magnetic probes l...
متن کاملTemperature gradient driven short wavelength modes in sheared slab plasmas
The temperature gradient (h i and he) driven instability in the short wavelength regime, ukyr iu .1, is studied in a sheared slab. An analytical analysis is performed first to clarify the physics mechanisms for the modes in a shearless slab. The correlation between the growth rate and the real frequency of the modes is discussed in detail. The electron temperature gradient is found to have stro...
متن کاملHigh-Yield Z-Pinch Thermonuclear Neutron Source
Introduction: Neutron beams are useful for many applications, from noninvasive imaging and characterization of materials to producing medical isotopes and detecting hidden explosive devices. Some applications require high-energy neutrons created in fusion nuclear reactions between deuterium (D) and tritium (T). To achieve thermal fusion, deuterium or DT plasma must be heated to about 10 8 K, wh...
متن کاملRotational stabilization of pinch instabilities in Taylor-Couette flow.
The axisymmetric linear stability of dissipative Taylor-Couette flow with an azimuthal magnetic field is considered. The magnetic field can be unstable without a rotation. This is the well-known pinch type instability. The stable rotation stabilizes the unstable azimuthal magnetic field. The dissipative flow stability can be classified according to Michael's stability condition for an ideal flo...
