In this thruster geometry, the electrically biased metallic anode is positioned at the base of the channel where the majority of the propellant gas is injected into the thruster. The remainder of the propellant gas used by the thruster is injected through the exterior hollow cathode. In the second version of this type of thruster, called a thruster with anode layer (TAL), the dielectric channel wall is replaced by a metallic conducting wall, as illustrated in Fig. 7-2. This geometry considerably shortens the electric field region in the channel where the ion acceleration occurs—hence the name “thruster with anode layer” from the Russian literature [1], associated with the narrow electric field region near the anode. However, this configuration does not change the basic ion generation or acceleration method. The channel wall, which is usually also part of the magnetic circuit, is biased negatively (usually cathode potential) to repel electrons in the ionization region and reduce electron-power losses. The defining differences between these two types of Hall thrusters have been described in the literature [3].PDF Image | Fundamentals of Electric Propulsion: Ion and Hall Thrusters

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
