Considerations on the role of the Hall current in a laboratory-model thrusterIEEE Transactions on Plasma Science - Tập 30 Số 2 - Trang 687-697 - 2002
J.M. Haas, A.D. Gallimore
Hall current magnitude and spatial distribution are presented for the plasma discharge in the University of Michigan/Air Force Research Laboratory P5 5 kW laboratory-model Hall thruster. The data are calculated from direct, probe-based measurements of the electric field, static magnetic field, and charged particle number density. Thruster discharge voltage was fixed at 300 V and two current levels...... hiện toàn bộ

Nickel-chrome-iron alloy film deposited by pulsed arc depositionIEEE Transactions on Plasma Science - Tập 30 Số 2 - Trang 725-727 - 2002
Changlong Cai, Jimei Wang, Yixin Yan, Lingxia Hang, Chang Zhu
In this paper, a technique for depositing nickel-chrome-iron alloy film using a pulsed arc deposition is introduced. The plating technique has been developed and the properties of the film deposited with the developed technique are measured. The results show that the difference of composition between the film and cathode material is less than /spl plusmn/3% and by adding an collimating electrode, ...... hiện toàn bộ

Qualitative fuzzy logic model of plasma etching processIEEE Transactions on Plasma Science - Tập 30 Số 2 - Trang 673-678 - 2002
Byungwhan Kim, Jang Hyun Park
Plasma etching is key to transferring fine patterns. Accurate prediction models are highly demanded to gain improved insights into plasma discharges, as well as optimization and control of plasma equipment. As an empirical approach, a fuzzy logic referred to as adaptive network fuzzy inference system (ANFIS) was used to construct a qualitative model for a magnetically enhanced reactive ion etching...... hiện toàn bộ
