“…Gatsonis et al [1,2], Eckman et al [3], Bryne [4], and Zwahlen [5] measured the profiles of electron temperature, density, and velocity of the plume field using the triple and quadruple Langmuir probe. Also, Yin [8] and Gatsonis and Yin [9] developed an axisymmetric model in a cylindrical coordinate system and employed the particle-in-cell (PIC) [12] and direct simulation Monte-Carlo (DSMC) [13] hybrid method to simulate the flow field.…”

“…The plume characteristics have been studied by many researchers [1][2][3][4][5][6][7][8][9][10][11] because it is of interest in the contamination assessment of electric thrusters and important for the investigation of plume-spacecraft interactions. The plasma plume of a rectangular geometry ablative PPT using solid Teflon for propellant is investigated.…”

“…Both experimental [1][2][3][4][5][6][7] and numerical [8][9][10][11] studies of the plume characteristics of the laboratory PPT have been carried out. Gatsonis et al [1,2], Eckman et al [3], Bryne [4], and Zwahlen [5] measured the profiles of electron temperature, density, and velocity of the plume field using the triple and quadruple Langmuir probe.…”

“…Based on comparisons with data by a triple Langmuir probe, the two-dimensional (2D) model predicted well the electron density of the flow field and was verified by the triple Langmuir probe measured data. Since the flow field of a rectangular PPT is inherently three-dimensional (3D), experimental measurements are commonly carried out in both parallel and perpendicular planes [1][2][3][4][5].…”

The plume characteristics of a pulsed plasma thruster (PPT) are considered necessary in the evaluation of plume/spacecraft interactions. In this article, the rarefied plasma plume of a laboratory PPT is characterized. First, a three-dimensional (3D) physical model with boundary conditions is presented. Then, the particle-in-cell and direct simulation Monte-Carlo hybrid methods are employed to study the flow field. The profiles of the plasma density and potential and their variations versus time are analysed. Also, the computational results are compared with experiment data as well as with results from existing two-dimensional (2D) simulations. The comparisons show that the computational model can predict the electron density of plume in both parallel and perpendicular planes. It is also shown that the 3D predictions are more accurate than those of the 2D model. Analysis of the plume backflow indicates that less than one thousandth of the mass that is released from the solid propellant enters the backflow region at the end of a pulse period.

“…23 When operated at 5, 10, and 40 J, the LES 8/9 PPT had a time averaged electron temperature of 1-3 eV and an electron density that varied from PPT studies by Thomassen and Tong found 40% of the exhaust plume is ionized at 3.5 mm from the Teflon surface, but that this percentage decreases to 18% by 16 mm.…”

This review details the state of the art in in-space plasma diagnostics for characterizing the Earth’s ionosphere. The review provides a historical perspective, focusing on the last 20 years and on eight of the most commonly used plasma sensors—most of them for in situ probing, many of them with completed/in-progress space missions: (a) Langmuir probes, (b) retarding potential analysers, (c) ion drift meters, (d) Faraday cups, (e) integrated miniaturized electrostatic analysers, (f) multipole resonance probes, (g) Fourier transform infrared spectrometers, and (h) ultraviolet absorption spectrometers. For each sensor, the review covers (a) a succinct description of its principle of operation, (b) highlights of the reported hardware flown/planned to fly in a satellite or that could be put in a CubeSat given that is miniaturized, and (c) a brief description of the space missions that have utilized such sensor and their findings. Finally, the review suggests tentative directions for future research.
