Patents by Inventor Christopher James Macdonald-Bradley

Christopher James Macdonald-Bradley has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8138692
    Abstract: A magnetic field crosses non-uniform rotating electric radial fields which are generated between a central electrode and a series of circumferential outer electrodes. Synchronous charging and partial discharging is applied to the outer electrodes, generating a rotating non-axisymmetric field. Charged particles may then be accelerated and held in a circular orbit, regulated by the magnitude and frequency of the charging of the electrodes, with a radius given by Bqwr=Eq+mw2r. The circular beam of particles so formed may be used for a variety of applications, which also includes fusion energy applications due to the high kinetic energy possible in the apparatus and the mechanism of energy recovery of scattered particles. Isotopic separation by charge to mass ratio is also possible, the device being essentially a cyclotron with radial electrodes.
