We analyze similarities and differences between electrostatic probe measurements and high-
speed visible light imaging measurements in a low-temperature argon helicon plasma …

Optical emission spectroscopy (OES) is an important noninvasive diagnostic tool for
providing insight into the plasmas of the negative ion sources. The plasma spectroscopic …

Amirkabir Helicon plasma source (AHPS) has been designed and developed at the fusion
laboratory of Amirkabir University of Technology for the neutral beam injection (NBI) system …

We calculate the intensities of the main rare gas plasma radiations, which are commonly
present in the plasma thrusters. Typical data used for these calculations are briefly reviewed …

In the present context, the extraction system of a helicon ion source has been simulated and
constructed. Results of the ion source commissioning at up to 20 kV are presented as well …

This thesis describes design, development and testing work on a plasma cathode electron
beam gun as well as plasma diagnosis experiments and Electron Beam (EB) current …

Non-invasive measurements are performed on a pulsed and steady-state argon helicon
plasma thruster with a static axial magnetic nozzle field (1 kG source, 1.5 kG nozzle peak) …

This work is motivated by the Variable Specific Impulse Magnetoplasma Rocket (VASIMR)
experiment. This device uses a helicon antenna to generate a plasma inside a dielectric …

A helicon thruster was developed to research the use of emission spectroscopy diagnostics.
Helicon thrusters differ from conventional electric propulsion systems in that the conductive …

Extrem ultraviolette (EUV) Lichtquellen sind zur Herstellung und Prüfung von immer kleiner
werdenden Transistorgrößen für die nächste Generation von Mikrochips erforderlich. Das …
