Ion production cost of a gridded helicon ion thruster
Helicon plasma sources are capable of efficiently ionizing propellants and have been considered for application in electric propulsion. However, studies that estimate the ion production cost of the helicon plasma source are limited and rely on estimates of the extracted ion current. The ion production cost of a helicon plasma source is determined using a gridded ion thruster configuration that ...
متن کاملDevelopment of the Linear Gridless Ion Thruster
The design of the Linear Gridless Ion Thruster, or LGIT, is presented in detail. The LGIT is a hybrid thruster that combines an ionization stage similar to those normally found on gridded ion engines with the acceleration mechanism of a Hall effect thruster. This thruster also features a linear geometry, which simplifies the design of the magnetic circuit while making the LGIT particularly well...
متن کاملIon Thruster Optical Performance Enhancement via Ion-emissive-surface Shaping
Numerical results that demonstrate how ion emissive surfaces should be shaped to induce the formation of well-focused, high-current beamlets are presented. Results obtained when the sheath shape and position are established and then held constant as operating conditions are changed are compared to corresponding results obtained with a conventional plasma sheath that moves. These comparisons sho...
متن کاملPotential Contours in Ion Focusing Hall Thruster
The Embedded Electrode Hall Effect Thruster is a modified 10 kW T-220HT with embedded graphite electrodes within the channel wall to study ion focusing for improved thrust-to-power ratio. Previous experiments with the thruster have demonstrated increased performance on xenon with biased electrodes caused by increases in ion energy, propellant efficiency, and a reduction in the plume divergence ...
متن کاملImplementation of a 1⁄4 Inch Hollow Cathode into a Miniature Xenon Ion Thruster (MiXI)
Over the last decade, miniature ion thruster development has remained an active area of research do to its low power, low thrust, and high efficiency, however, due to several technical issues; a flight level miniature ion thruster has proved elusive. This thesis covers the design, fabrication, assembly, and test of an altered version of the Miniature Xenon Ion thruster (MiXI), originally develo...
