92 Chapter 4 Hollow Cathode Gas Feeds Anode Wall Xe+ e− Magnetic Confinement Fig. 4-1. Illustration of a DC-discharge electron bombardment ion thruster. ionization probability of the in- jected electrons. Proper design of the magnetic field is critical to providing sufficient confinement for high efficiency while maintain- ing adequate electron loss to the anode to produce stable discharges over the operation range of the thruster. Several power supplies are re- quired to operate the cathode and plasma discharge. A simplified electrical schematic typically used for DC-discharge plasma genera- tors is shown in Fig. 4-2. The cathode heater supply raises the thermionic emitter to a sufficient temperature to emit electrons, and is turned off once the plasma discharge is ignited. The keeper electrode positioned around the hollow cathode tube is used to facilitate striking the hollow cathode discharge, and also protects the cathode from ion bombardment from the discharge chamber region. The cathode and keeper are discussed in Chapter 6. The discharge supply is connected between the hollow cathode and the anode, and normally is run in the current-regulated mode in order to provide a stable discharge at different power levels.

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
