N2 – Design of the proper power system for an improved ablation-fed pulsed plasma microthruster PPT requires the ability to specify amplitudes, risetimes, waveforms and pulsetimes in relation to propellant properties and thrust chamber dimensions. Modeling of ablation-fed pulsed plasma thrusters P. In particular, the thin approach leads to large velocity gradients at implosion not found with the non-local model. Such erosion tends to increase with higher currents, blocking higher yields. Analysis of an Experimental Pulsed Plasma Accelerator.

N2 – Design of the proper power system for an improved ablation-fed pulsed plasma microthruster PPT requires the ability to specify amplitudes, risetimes, waveforms and pulsetimes in relation to propellant properties and thrust chamber dimensions. Gas puffs imploded onto the axis before the peak of a generator current at ns.

This result suggests that the reduced line opacity due to the inclusion of Doppler shifts could significantly affect the plasma dynamics and Kr K-shell emission. The mass ablated per shot then scales as the stored electrical energy, in pulsinf with experiments over a wide range of operations.

The experimental results, that include ionization of Puosing impurities up to the H-like stage, support model simulations in showing that rapid ohmic heating of micro-capillary channels with relatively modest currents can generate very hot dense plasma columns which electron temperature could approach 1 KeV.

Magnetic field generation during the nonlinear phase of the Rayleigh–Taylor RT instability in an ablatively driven plasma using ultrafast laser-driven proton radiography has been measured. Extreme degree of ionization in micro-capillary plasma columns heated by ultrafast current pulses Jorge Rocca, Jing Li, Gonzalo Avaria, Michael Grisham, Fernando Tomasel, Vyacheslav Shlyaptsev The efficient generation of dense large-scale plasma columns with very high degree of ionization and high homogeneity can enable fundamental plasma studies and a variety of promising applications.

Our fully kinetic particle-in-cell simulations have reproduced observed DPF ion beams.

Ultimate results in a 2J portable PF device as non radioactive neutron source for field applications are presented. In addition, simulations have indicated that if the initiation points on the inner edge of the cathode are set too closely, filaments of current will collide chaotically, rather than emerging as isolated and identical structures, also impairing symmetrical compression.

The experimental data are in good agreement with predictions from 2-D magnetohydrodynamic simulations. Instabilities are seen to develop in the downstream regions.

Heat transfer to the surface occurs in a thinner layer within this discharge, and provides a mass flow rate proportional to the electrical power. Skip to main content. Plasmas 19, ; Y.

Initial 2D modulations with spatial pulsinh of 30, 70, and um were imprinted on targets by laser beams using special 2D phase plates. We show how the current pulse can be shaped in order to isentropically compress the DT ice layer.

In experiments with FF-1, a mega-amp PF facility, we have found that going beyond this plateau requires elimination or extreme minimization of erosion of metals into the plasma sheath. Abstract The purpose of this study was to gather and analyze data taken from a laboratory Pulsed Plasma Accelerator to understand its operation, and also for future comparison of the experimental data with predictions made with computer simulations based on the codes named MACH2 and GEMS.

For best results, right-click and select “save as The obtained pulse shape enables us to simulate a cylindrically convergent ramp wave, which quasi-isentropically compresses the Deuterium fill to densities much higher than achievable by using a standard pulse.

We also show measurements of the B-field inside the liner, using miniature Bdot probes, which show a dependence on the liner diameter and thickness. Plasmas 17, In this work we study the power and yield from a Kr gas puff on the refurbished Z generator using the MACH2-TCRE simulation code in R-Z coupled to four different models for the radiation transport of bound-bound transitions within the probability-of-escape formalism: Outer, middle, and inner nozzle diameters were mm, 80 mm and 30 mm, respectively.

Data was collected from three different instruments: We present a study investigating the initiation of plasma in solid, metallic liners where the liner thickness is large compared to the collisionless skin depth.

This in turn allows a study of the response of the liner to the current pulse.

We have addressed these various obstacles in a set of experiments and report on results.
