TL;DR: In this article, two arcjet Power Conditioning Units (PCU) were recently tested wtih offsite arcjet thrusters, and the major thrust of the tests was on thruster performance, so the technical objectives and interests of these tests were not limited to the PCU performance.
Abstract: Two arcjet Power Conditioning Units (PCU’s) were recently tested wtih off‐site arcjet thrusters. The arcjet PCU’s used in these in these tests were designed and built by SPI. The design of PCU I.1 was based on our previous work in arcjet power conditioning funded by AFAL. SDIO‐SBIR funded the development of PCU II, modification of PCU I.1 and PCU I.2, as well as the testing of these PCUs. The first of these recent tests was conducted at NASA Lewis Research Center with a hydrogen arcjet. The second one was conducted in Jet Propulsion Laboratory with an ammonia arcjet. The major thrust of the tests was on thruster performance, so the technical objectives and the interests of these tests were not limited to the PCU performance. SPI’s major objectives of these tests were to demonstrate the stable operation of the PCU’s with arcjet thrusters, to prove the capability of initiating the arc breakdown with its built‐in starter, and to demonstrate the endurance of the PCU. The personnel at NASA LeRC and JPL successfully operated the SPI PCUs with their arcjet and obtained valuable test data.

TL;DR: In this paper, a plasma arcjet was constructed to study the fundamental reaction kinetics for decomposition of hazardous liquids and a surrogate liquid waste, 1,2 dichloroethane, was injected into the plasma jet and the decomposition byproducts were monitored using a residual gas analyzer.
Abstract: Summary form only given. A plasma arcjet reactor has been constructed to study the fundamental reaction kinetics for decomposition of hazardous liquids. The arcjet was operated at a power level of 1.5 kW and an argon flow rate of 17.5 LPM. The temperature profile of the plasma jet was measured using an enthalpy probe and the maximum temperature measured in the plasma jet was 1850/spl deg/C. A surrogate liquid waste, 1,2 dichloroethane, was injected into the plasma jet and the decomposition byproducts were monitored using a residual gas analyzer. A removal efficiency greater than 99% was obtained. The temperature profile was used to model the arcjet as a non-isothermal tubular now reactor.

TL;DR: In this article, a flame diagnostic Multiphoton Laser Induced Fluorescence (LIF) was applied to the excited-state plasma environment to investigate concentration levels of atomic ground-state hydrogen.
Abstract: : Pulsed Plasma Thrusters (PPT) have been the major technology under investigation for the Small Satellite Electric Propulsion Thruster Research program Arcjet technology is also under investigation with Electric Propulsion Space Experiment Optical Signature experiments underway and Multiphoton Laser Induced Fluorescence Measurements of Ground State Atomic Hydrogen have been performed in an arcjet plume At present PPTs are being tested in the laboratory environment with investigations under way to determine exact inefficiency mechanisms that can be corrected This work has already identified previously unknown physical behavior in the PPT The Electric Propulsion Space Experiment is a flight demonstration of a 30 kW ammonia arcjet propulsion system Optical measurements of the arcjet plume were performed using on-board optical equipment ground observatories and other space platforms Low power arcjet technology provided definitive work on atomic species plume concentrations in low power hydrogen arcjet plumes This work applied a flame diagnostic Multiphoton Laser Induced Fluorescence to the excited-state plasma environment to investigate concentration levels of atomic ground-state hydrogen
