  • Micro-Cathode Arc Thruster Development and Characterization
    2020
    Co-Authors: Taisen Zhuang, Alexey Shashurin, Dereck Chiu, George Teel, Michael Keidar
    Abstract:

    The performance of the micro-cathode arc thruster (μCAT) and coaxial micro-cathode arc thruster (CA-μCAT) have been investigated. In particular, Mass Consumption rate of these thruster variants was measured. Using the Mass Consumption rate, the specific impulse of the μCAT was calculated from the thrust data and compared to the ion velocity measurements. This comparison suggests that plasma plume is highly ionized. Moreover, two thruster performance have been compared. The potential application for both thruster have been discussed in the paper.

  • performance characteristics of micro cathode arc thruster
    Journal of Propulsion and Power, 2014
    Co-Authors: Taisen Zhuang, Alexey Shashurin, Michael Keidar, Thomas Denz, Patrick Vail, Anthony Pancotti
    Abstract:

    This paper describes measurements of performance characteristics of micro-cathode arc thruster. In particular, influence of an applied magnetic field B on the impulse bit, specific impulse, and the Mass Consumption is investigated. The micro-cathode arc thruster was operated in a quasi-steady-state mode to ensure that a measurable thrust stand deflection was produced. It was found that the impulse bit increases from about 0.1  μN·s in the case without a magnetic field up to about 1.1  μN·s in the case of a magnetic field of about 0.3 T. A magnetic field leads to an increase of the Mass Consumption from about 10  μg/C at zero magnetic field up to about 50  μg/C at a magnetic field of about 0.3 T. Average ion velocity is measured to be about 18  km/s (at B=0  T) and about 31  km/s (at B=0.3  T). Maximum efficiency of the thruster is estimated to be about 7%.

  • Mass-Consumption as an activator of sustainable consumerist potentials
    2020
    Co-Authors: Magnus Boström, Mikael Klintman
    Abstract:

    This chapter focuses on the relation between Mass-Consumption and sustainable Consumption.Mass-Consumption concerns the omnipresent role of Consumption in contemporary societieswith its problems of excessive resource use in current practices of Consumption. The latemodern context and forces of Mass-Consumption can both trigger and prevent sustainableConsumption as well as shape its outcome. Through a literature review, both the examples ofalternative Consumption (e.g. buycotts) and various kinds of anti-Consumption, which involvepolitically motivated ambitions to cut down on Consumption, are addressed. The chapteraddresses different ways in how Mass-Consumption activates sustainable consumeristpotentials, including sentiments towards anti-Consumption. It also shows how MassConsumptionmakes people unable to link Consumption to political considerations, and enterspaths towards political anti-consumerism or realise their ambitions. Finally, the chapteranalyses possibilities and difficulties transforming niche sustainable consumerist initiatives tothe mainstream in a society dominated by Mass Consumption.
