A novel experimental method is proposed for observing plasma dynamics subjected to magnetic fields based on a newly developed cylindrical theta-pinch device. By measuring simultaneously the temporal profiles of multiple parameters including drive current, luminosity, density, and temperature, it provides basis theta pinch, such as shock transport magnetohydrodynamic instability. We show that ev...

The blackout problem suffered by hypersonic vehicles as they re-enter the atmosphere is essential for effective communication of vehicles. Aiming to solve this problem, in paper, we proposed an antenna–sheath–plasma layer configuration, which a thin plasma covered cylindrical metal antenna model employed investigate radiation enhancement phenomenon solving dispersion equation electromagnetic mo...

Externally driven, vertically polarized transverse dust-lattice waves were observed in a one-dimensional strongly coupled dust chain levitated in the plasma-sheath boundary of a dc argon plasma at low gas pressure around 5 mtorr. Real and imaginary parts of the complex wave number were measured in the experiments. The experimental result clearly shows that the observed transverse dust-lattice w...

2014 Spatially resolved spectroscopic diagnostics such as plasma-induced emission, laser-induced fluorescence and laser optogalvanic spectroscopy are used to characterize the cathode sheath and the negative glow of an abnormal glow dc discharge in nitrogen. These diagnostics provide local information on the excitation and ionization functions, on the concentrations of ions and on the rotational...

Overview of recent progress in studies of magnetized dusty plasmas is presented. Dust dynamic under the influence of an applied magnetic field in various types of discharges and conditions (including dust dynamic in the magnetized plasma sheath) is examined. The various dust driven mechanisms in magnetized plasma are considered and comparison experimental and theoretical data is performed. Infl...

The peripheral nerves consist of sensory nerves that transmit somatic and visceral afferent information to the brain via the spinal cord and motor nerves that convey efferent outputs of the brain to effector organs such as skeletal muscles and glands. The nerve conduction velocities (NCV) of mammalian peripheral nerves range from 10 m/s to 150 m/s, depending on the type of information being tra...

The interaction of ultraintense laser pulses with solids is largely affected by the plasma gradient at vacuum-solid interface, which modifies absorption and ultimately, controls energy distribution function heated electrons. A micrometer scale-length has been predicted to yield a significant enhancement weight fast electron population play major role in laser-driven proton acceleration thin foi...

For a weakly collisional two-ion species plasma, it is shown that the minimum phase velocity of ion acoustic waves (IAWs) at the sheath-presheath boundary is equal to twice the phase velocity in the bulk plasma. This condition provides a theoretical basis for the experimental results that each ion species leaves the plasma with a drift velocity equal to the IAW phase velocity in the bulk plasma...

Silicon nanowires were selectively grown at temperatures below 400 °C by plasma enhanced chemical vapor deposition using silane as the Si source and gold as the catalyst. A detailed growth study is presented using electron microscopy, focused ion beam preparation, and Raman spectroscopy. A radio-frequency plasma significantly increased the growth rate. The Si nanowires show an uncontaminated, c...

CO2 laser-plasma interactions provide a unique parameter space for using a gas jet for Target Normal Sheath Acceleration (TNSA) of ions instead of a thin foil target. The generation of 1-5 MeV protons from the interaction of a 3 ps TW CO2 laser pulse with a gas target with a peak density around the critical plasma density (10 cm) has been studied by 2D particle-in-cell simulations. The proton a...
