Definitions

  • the present invention relates to improvements in processes and devices for producing energy by nuclear fusion, and seeks to increase the efficiency of thermonuclear reactors, while mitigating the disadvantages enumerated above.
  • a cylindrical reactor in which a high degree of vacuum has previously been set up, has introduced into it a gas or a mixture of gases through orifices situated in the curved wall of the reactor, and the said gas or mixture of gases, which takes the form of a cylindrical layer, is then subjected to an electrical discharge.
  • the gas is preferably a mixture of deuterium and tritium.
  • the vacuum which has been set up in the cylindrical reactor may be of the order of 10 mm. of mercury, and an applied potential may be used from a source producing an electrical discharge of the order of ten kilovolts.
  • the gas or mixture of gases may advantageously be ionised before being introduced into the reactor.
  • the reactor for use in this process comprises a cylinder with circular ends, whereon the curved wall is of insulating material, preferably ceramic, and includes orifices.
  • FIGURE 2 represents a partial plan view of the device of the invention.
  • FIGURE 1 represents a cross-section of the device of the invention along line A--B of FIGURE 2.
  • FIGURE 2 the perspective view is shown corresponding to that viewed along arrow C of FIGURE 1 and broken away along line DE of FIGURE 1.
  • the devices which will be described in connection with this example must be considered as forming part of the invention without limiting it, it being understood that any equivalent variants may be used without departing from the scope of the invention.
  • FIGURES 1 and 2 two circular electrodes 1 and 2 in the form of thin circular blades are attached to the inner parallel walls 24 and 25 of circular insulating material which form the ends of a cylindrical volume inside which the pressure is of the order of 10 mm.
  • a high voltage source 18 supplying about ten kilovolts is connected to electrode 1 through the lead 17 and connected to electrode 2 through switch 19, the condenser 3 and the lead 20;
  • the curved wall 10 of the cylinder is made of insulating material; this wall 10 includes a series of small orifices 11 situated at a distance R(12) from the central axis of symmetry 13 of the cylinder.
  • the device is enclosed in the annular insulating part 21 provided with four gas inlets 22.
  • a cylindrical layer of gas 14 is injected into the cylinder through the orifices 11 between the electrodes 1 and 2.
  • This gas may be previously ionised, but ionisation will in any case take place when high potential from the source 3 is applied between the electrodes 1 and 2.
  • the said layer will be subjected to a force IB (arrow 15), wherein I is the value of the discharge current, and Bcp the field produced by this current.
  • IB arrow 15
  • the layer of ionised gas will contract in the vacuum, and will not lose its kinetic energy.
  • the said layer will be radially compressed, and will attain a thickness 6 (16,
  • FIGURE 1 whereof the value is approximately:
  • the minimum radius R of the concentrated electrical discharge (pinch) thus formed is of the same order of magnitude as 5, that is to say 1.5 to 2 mm.
  • a discharge is thus produced at very high temperature on the one hand because of the absence of loss by contraction against a gaseous medium, and on the other hand because of the very small radius of the concentrated electrical discharge.
  • a reactor for nuclear fusion comprising a pair of spaced cylindrical electrodes, means for applying an electrical discharge between said electrodes, means for applying a high vacuum between said electrodes, a cylindrical insulating Wall between said electrodes forming a reaction chamber, said wall adapted to contain a low pressure atmosphere of a gas to be operated upon having small:
