Helicon Source for Ion Propulsion
نویسنده
چکیده
Electric thrusters are usually in one of two forms: gridded ion thrusters or Hall thrusters. Each of these accelerates ions and requires an injector of electrons to neutralize the ion beam. Ambipolar thrusters eject neutralized plasmas with equal numbers of ions and electrons. Helicon thrusters are a new type being developed which utilize both the high ionization efficiency of magnetized helicon discharges to produce dense plasma and the properties of an expanding magnetic field to accelerate the ions.

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 ...

The ongoing development of the Variable Specific Impulse Magnetoplasma Rocket (VASIMR) involves basic physics analysis of its three major components: helicon plasma source, ion cyclotronresonance heating (ICRH) module, and magnetic nozzle. This paper presents an overview of recent theoretical efforts associated with the project. It includes: 1) a first-principle model for helicon plasma source,...
متن کاملUsing a helicon source to simulate atmospheric re-entry plasma densities and temperatures in a laboratory setting
The purpose of this research is to develop a plasma system capable of reproducing plasma densities found during atmospheric re-entry of a capsule. We developed a 150 mm diameter helicon source at the University of Michigan Plasmadynamics and Electric Propulsion Laboratory (PEPL) and used a Langmuir probe to characterize plasma properties downstream. The helicon source was operated with argon ga...
متن کاملFeasibility study of low power helicon thruster
Abastract Helicon thrusters have been recently considered a possible new electric propulsion system thanks to the acceleration mechanism called “current free double layer “ which allows specific impulse up to 1300 s applying Argon and 4000 s applying hydrogen. Although the primary interest of this technology was always regarding primary propulsion , on this paper is explored the possibility of ...
متن کاملDesign of an Experiment for Studying Ion Acceleration by Beating Waves
The design and implementation of an experiment dedicated to the testing of recently derived criteria for ion acceleration by beating electrostatic (ES) waves are discussed. The non-resonant energization of the magnetized ions by the beating waves is potentially a highly-efficient process and thus of interest to propulsion. A cylindrical magnetized plasma source was constructed and uses either a...
