Electrostatic plasma confinement and magnetic electrostatic plasma confinement (MEPC) have been studied for four decades. The multiple potential well hypothesis, postulated to explain high neutron yields from Hinch's colliding beam experiment, has been supported by several pieces of evidence, but results were inconclusive. Magnetic shielding of the grid was developed to reduce the required beam current and to prevent grid overheating. Electrostatic plugging of magnetic cusps evolved to a similar confipuration. Due to low budgets, early MEPC experiments used spindle cusps, which are poor for plasma confinement. Later experiments used multipole cusps or a linear set of ring cusps, which have larger volnmes of field-free plasma. To keep the self-shielding voltage drop A+ S 100 kV, the electron density n, in the anode gap should be less than about 10'9m-3. The central plasma density can be an order of magnitude higher. The ATOLL toroidal quadrupole had anomalous electron energy transport, but the Jupiter-2M linear set of ring cusps achieved a transport rate about a factor of two above the classical rate. With near-classical transport, a power gain ratio Q = 1 0 is predicted for a reactor with r p = 3 m , B,=6T, and applied voltage + , =400 kV. Besides producing electricity and synthetic fuels, MEPC reactors could be used for heavy ion beams sources and neutIon generators. The main issues of concern for MEPC reactor development are electron transport, plasma purity and electrode alignment and voltage holding.= 100 kV, zP = 0.1 s and d = 0.001 m, this equation gives R > 2.5 m.

“…Understanding the behavior of the recirculating electron beam as it passes back and forth through the anode gap is crucial to the design of any MET reactor. Optimizing the geometric shape of hypothetical anode gaps to increase the power-balance Q is the subject of a second Yushmanov study [17]. Yushmanov only considered a rectangular gap, parameterized by width and depth.…”

Particle in Cell (PIC) simulation has been used to design a quasi-spherical, net power, deuterium fueled, fusion reactor incorporating high temperature superconducting (HTS) magnets. Using the principles of Magneto-Electrostatic Trap design of Yushmanov(1980) the reactor is predicted to have power-balance Q = 7, improving on the classic Polywell design by incorporating HTS magnets and a high-current deuteron ion beam. With these improvements, a hexahedral reactor of only 4m diameter is predicted to produce 100 megawatts of net power, in a design that is suitable for practical commercial fusion power production.
