Collimated RPA data for the BPT-4000 showing the angle- independent, high-energy main beam peaks and the angle-dependent, elastic scattering peaks (from [9]). transfer) between beam ions and neutral atoms. Numerical simulations using calculated differential scattering cross sections confirm that elastic scattering is the cause of the observed mid-energy peak [10]. 8.3 Plume Models 8.3.1 Primary Beam Expansion Before the advent of multi-dimensional computer models of thruster plumes, empirical models of the primary beam expansion were used. These models reproduce the general features of the ion beam angular distribution. Because they are very simple, they are invaluable for initial trades when planning electric propulsion system accommodation on spacecraft. Parks and Katz [11] derived an analytical model of the expansion of an ion beam with a Gaussian profile in its self-consistent, quasi-neutral electric field with or without an initial distribution of radial velocities. This model is very useful for analytically calculating thruster ion-beam plume characteristics. The steady-state ion continuity and momentum equations in the absence of ionization are 60° 0 50 100 150 200 250 300 Energy/Charge (V)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
