The plasma plume expansion could also lead to the generation of shockwaves. In addition, the laser-matter interactions are associated with mechanical stress due to thermal expansion or the propagation of shockwaves, which can cause another kind of ablation by spallation if the amplitude exceeds the binding strength of the lattice within the target.

Hosted by Brian Greene and based on his best-selling book of the same title, \textit{The Fabric of the Cosmos }is a new four- part NOVA series that explores the deepest mysteries of space and time. The program was kicked-off by 30 Cosmic Cafes'' being held around the country funded by an NSF grant which allows SPS-NOVA to fund SPS chapters.

[Eric J Pencil; United States. plume is therefore more energetic than a resistojet plume. As a result of the arc, electronic excitation, ionization, and dissociation occur in the nozzle.

Immediately downstream of the nozzle, the plume is a rapidly-expanding, partially-ionized plasma in which recombination and de-excitation take place.

In order. 10 Lau, M. and Herdrich, G., “Plasma diagnostic with inductive probes in the discha rge channel of a pulsed plasma thruster,” Vacuum, pp. The simulation of stationary plasma thruster plume is important for spacecraft design due to possible interaction plume with spacecraft surf ace.

Such simulations are. a follow up to a previous study 5 where only partial far-field planes of a PPT were examined.

The objective of the research presented in this article was to determine the symmetry/asymmetry of a PPT plume by characterizing the films deposited on local witness plates.

The films collected from the thruster discharge were characterizedFile Size: 1MB. from the far field to very near field of a Hall thruster plume.

Recent work in this vein has applied statistical methods to create transfer functions between the thruster discharge current and spatially resolved plume plasma properties, permitting a time-resolved reconstruction of plume properties from temporally disparate probe measurements.

on how the plasma potential in the thruster plume and the ionization and acceleration processes internal to the thruster were affected by changes of the magnetic field and discharge voltage.

EXPERIMENTAL APPARATUS The thruster hardware and configuration were the same as the experiments reported in Ref. This included the thruster, power. Computer models of Hall thruster plumes play an important role in integration of these devices onto spacecraft as the space environment is not easily reproduced in ground testing facilities.

In this article, a hybrid particle-fluid model of a Hall thruster plume is applied to model the SPT thrusters used on the Russian Express by:   This site uses cookies. By continuing to use this site you agree to our use of cookies. To find out more, see our.

Although there have been many studies of Hall thruster plume characteristics, the combined data of the very-near-field and the near- and far-field plume studies provided the most comprehensive collection of plasma parameters in the Hall thruster by: In operation, gaseous xenon effuses from the thruster acceleration channel.
