“…The staged pinch dynamics can be divided into two parts namely the outer z-pinch plasma dynamics and the inner -pinch dynamics. The dynamical equation for the outer double gas-puff z-pinch plasma based on a modified snow-plow model [20] can be expressed as…”

“…In the past, Nasim et al [19], have investigated the dynamics of a two-gas gas-puff z-pinch plasma with different forms of applied current profiles by using a modified snow-plow model [20]. In this paper, we have investigated the detailed dynamics of double gas-puff staged pinch plasma using a modified snow-plow model with kinetic pressure effects.…”

The implosion dynamics of a dense θ-pinch plasma driven by a double gas-puff z-pinch is re-examined in the presence of kinetic pressure. A modified snow-plow model has been used to describe the dynamics of such a staged pinch plasma. The inclusion of kinetic pressure introduces the usual plasma β-term. Numerical results demonstrate that the thermonuclear fusion parameters can be achieved in a dense θ-pinch Deuterium-Tritium (D-T) fiber plasma for an optimum choice of density ratio of the test to driver gas at the interface position (α-parameter) of imploding z-pinch plasma and kinetic to magnetic pressure ratio (β-factor). Thus double gas-puff staged pinch device can be a more feasible approach to achieve fusion conditions with an enhanced stability.

“…The plasma propulsion has been reported in several pieces of research of high-density plasma in the last two decades. [1][2][3] The plasma propulsion can be classified according to the device input power to low-energy (few kJ) 4) and high-energy plasma propulsion (>50 kJ). 5) Pulsed electromagnetic propulsion devices usually use an intense surge of electrical current to create a high-speed jet of plasma 6) which can provide many advantages over the fusion-based thruster concepts and may be possible in the near-term and fusion space thruster based on the flow-stabilized Z-pinch.…”

This paper presents preliminary results for a new design of a pulsed linear plasma device that generates electromagnetic plasma propulsion. The current sheath dynamics and the plasma propulsion along an extension tube have been studied. Breakdown of helium gas occurs between coaxial electrodes when applying a high-voltage pulse. This paper presents measurements with a number of probes, as well as camera images of the plasma propagation. A plasma is ejected and fills a 40 cm length extension tube. Additionally, the measurements show that the length of the propelled plasma column and its intensity inside the expansion tube is increased by increasing the charging voltage, while the plasma propulsion current is decreased along the extension tube. It is noted that a lower critical time; 4.7 μs, is needed to ionize the gas and form the plasma current sheath.
