  • the present invention relates generally to the field of plasma physics. More particularly, the invention concerns a method and apparatus for compressing plasma to a high energy state.
  • MCF Magnetic Confinement
  • ICF Laser Inertial Confinement
  • ITER International Thermonuclear Experimental Reactor
  • NEF National Ignition Facility
  • ICF attempts to hold a high-density 10 m " plasma for nanoseconds.
  • Magnetized Target Fusion mitigates the problems encountered at either extreme by sustaining a medium-density 10 24 m "3 plasma for only several milliseconds, while simultaneously reducing the minimum reactor size and cost as compared to MCF or ICF.
  • the University of Washington Plasma Physics Laboratory has long advocated cleanliness requirements to avoid plasma impurities. They also utilize newer and more efficient methods to form and accelerate compact toroids.
  • the pure research of the University is not focused on advanced plasma compression for MTF and the University has not attempted to translate a CT along a curved wall made of beryllium or lithium-silicon, which are much lower-Z materials than their walls (made of silicon dioxide).
  • Prior art compact toroid compression mechanisms include, but are not limited to the following:
  • Hydraulic hydro-forming wall
  • Such mechanisms which require sub- microsecond-precision timing, require highly complex control systems.

  • the thrust of the present invention is to provide a compact toroid plasma structure compression assembly that is superior to and overcomes the problems associated with the various mechanisms described in the preceding paragraphs. More particularly, through analysis of the disadvantages of the aforementioned prior approaches, it has been possible to derive a unique set of design features that yield a novel approach with a distinct advantage. The details of these novel design features will be described further in the specification that follows. With the foregoing in mind, it is an object of the present invention to provide a compressor assembly of novel design within which a plasma can be efficiently compressed to a high energy state.

  • Another object of the invention is to provide a method for compressing a CT to a high-energy state using a compressor having an elongated spiral passageway by injecting the CT into the spiral passageway in a manner to avoid ricochet of the CT along the walls of the passageway. More particularly, in accordance with the method of the invention, ricochet is avoided by ensuring that the bulk axial kinetic energy of the CT at the point of injection is greater than the design "target" thermal energy sought to be achieved at the end of compression.
  • Another object of the invention is to provide a method of the character described in the preceding paragraph in which thermal conduction losses and particle diffusion losses are avoided by embedding a large magnetic field within the CT during formation, prior to launching the CT into the elongated spiral passageway.
  • a highly magnetized CT impedes both thermal conduction losses and particle diffusion losses perpendicular to the embedded magnetic field lines.
  • Another object of the invention is to provide a method of the character described in the preceding paragraphs, in which thermal conduction losses and particle diffusion losses are avoided by applying a plasma-impurity impeding coating to the walls of the elongated spiral passageway.
  • these coatings include low atomic number materials, such as beryllium or lithium-silicon.
  • Another object of the invention is to provide a method of the character described in the preceding paragraphs in which, following compression of the CT to the design "target" thermal energy, the CT is introduced into a burn chamber comprising a toroidal ring of constant cross-section having at least one entrance port for the compressed CT and having a multiplicity of smaller exhaust ports.
  • Another object of the invention is to provide a method of the character described in which, following compression of the CT to the design "target" thermal energy, the CT is introduced into a burn chamber and after the burn is complete, the compressed CT is caused to dissipate into a neutral gas, which is pumped out of the burn chamber by means of a suitable vacuum pump.

  • beryllium alloy material in constructing the compressor is somewhat less desirable than the use of the more common materials such as steel, copper, silicon, magnesium, tungsten or other refractory alloys, all of which absorb x-rays better than beryllium. Additionally, the use of these materials is considerably less hazardous and the materials combine the function of a vacuum structural wall and x-ray shielding wall into one component.

  • the compression apparatus is used to compress a deuterium-rich gas to ignition and/or "burn" conditions, a portion of the burn ash will contain the rare gas helium-3.

  • the first step in carrying out the method of the present invention is to form a compact torus (CT) plasma structure.
  • CT compact torus
  • FRC Field Reversed Configuration
  • An FRC is formed in a cylindrical coil which produces an axial magnetic field.
  • an axial bias field is applied, then the gas is pre-ionized, which "freezes in” the bias field, and finally the axial field is reversed.
  • the ends reconnection of the bias field and the main field occurs, producing closed field lines.
  • the CT which is identified in the drawings by the numeral 68, is launched at high speed into the inlet port component 42 of the plasma compressor of the invention.
  • the CT As will be discussed in greater detail in the paragraphs that follow, as the CT travels through the plasma compressor it is crushed against a low atomic number material wall of the elongated spiral by means of its own inertia, inducing heating by conservation of energy.
  • the internal thermal energy of the CT increases as its kinetic energy decreases.
  • the pressure force it exerts has a vector component in the opposite direction to its forward motion (unless the walls are of constant cross-section). Therefore, it is important that the bulk axial kinetic energy of the CT at the point of ejection be greater than the design "target" thermal energy at the end of compression, to avoid a ricochet effect along the walls.
  • a highly magnetized CT impedes both thermal conduction losses and particle diffusion losses from its core to the walls.
  • the compressed CT 68a Once compressed to the design "target" thermal energy, the compressed CT 68a enters a comparatively short transfer conduit 70, which guides it away from the plane of symmetry of the compressor, and into the burn chamber 41.
  • the burn chamber comprises a toroidal ring of constant cross-section, with a single entrance port for the compressed CT 68a ( Figures 3 and 7), and multiple smaller exhaust ports 72 ( Figure 5) which are in communication with the vacuum system 24.
  • the compressed CT 68a dissipates into neutral gas, which is pumped out through the main vacuum exit port 74.
  • the inner ring is provided with a circular hole 78, which is adapted to receive an alignment gauge pin during assembly (not shown). After assembly, the alignment gauge pin is removed, leaving two through-holes that can be conveniently used for the insertion of diagnostic probes, such as a Rogowski coil loop.
  • a major advantage of the method of the present invention is that neutral beams are not necessary for heating the plasma, maintaining the compact toroid plasma thermal energy, or providing stability to the plasma structure. Another advantage of the method is that collapsible walls are not needed for compressing the plasma. Additionally, in practice, the compression apparatus of the invention can be used multiple times.
  • the reaction cycle consists of the following five equations:
  • These features will minimize losses due to impurities entering the plasma from the walls.
  • Bremsstrahlung radiation is strongly affected by the average ion charge Z of the plasma, as the multi-pole non-relativistic equation A.2 ( Figure 10) indicates.
  • Bremsstrahlung occurs in the x-ray spectrum and leaves the plasma.
  • Bremsstrahlung is dominant only at high energy levels that are commensurate with burn conditions. For this reason, and the fact that the plasma is transparent to x-rays, Bremsstrahlung is usually the primary loss mechanism considered in simulation programs.
  • recombination and excitation line radiation dominate the plasma's radiative loss mechanisms. This is especially the case for high-impurity content plasma.
  • Recombination radiation governed by equation A.3 ( Figure 10) is the loss most strongly affected by Z. As can be seen inside the integrand, recombination radiation is extremely sensitive to increases in Z. It can be orders of magnitude less than Bremsstrahlung for a pure hydrogenic plasma, but can rapidly exceed Bremsstrahlung at lower energy levels from even moderate impurity content. Thus, by controlling impurities, the recombination radiation loss mechanism can be minimized Similarly, excitation line radiation in equation A.4 ( Figure 10) is affected by Z. Although not as apparent from this top-level equation, the calculation of N a utilizes a nonlinear function with Z as a directly dependant variable.
  • Recombination and line radiation are often over-looked in sizing calculations, as they are assumed to be negligible as compared to Bremsstrahlung. This is the case under certain circumstances, but it is important to include their equations in case impurities enter the plasma. Overall, it is always beneficial (loss-reducing) to minimize the average Z. This is best accomplished by keeping impurities out of the plasma by utilizing clean, low-Z walls that sputter at as low a rate as possible.
  • simulating sputtering of impurities from the wall (equation A.16 - Figure 12) and tracking magnetic dissipation (equation A.7 - Figure 10) allow estimation of how many impurities a wall will impart to a transient plasma and how long its internal magnetic field will last, respectively.
  • the remaining effects of ion-to-electron kinetic transfer collisions (equation A.12 - Figure 1 1), product energy ion apportionment (equation A.13 - Figure 1 1), product energy ion thermalization (equation A.14 - Figure 12), and particle thermalization (equation A.17 - Figure 11) are essential to accounting for the allotment of energy and particles coming from core burn dynamics. In effect, they determine not the burn rate, but rather how to apportion the fusion energy coming from the original gain equation A.1 , given the state of the plasma as instigated by an external device.
  • a convenient diameter for the starting and ending CT is 137 and 19 millimeters, respectively.
  • the initial embedded magnetic field is preferably on the order of 6 ⁇ 1 Tesla and the minimum initial plasma ion density is approximately 5xl0 15 particles per cubic centimeter.
  • the ejection speed of the CT requires a minimum of 4.8x10 6 meters per second and the minimum amount of time required for compression is on the order of 2 microseconds.
