  • Electron beam experiments, both those that have been carried out in space and those being planned, are reviewed. In these experiments, the emission of an electron beam from a satellite has made it possible to observe several types of wave excitation. The satellite potential and the energy spectrum of the returning electrons are measured by Langmuir probes and electrostatic energy analyzers. In the K-10-11, K-10-12, K-9M-57, K-9M-58, K-9M-61, and K-9M-66 rocket experiments, several types of electron guns were used with powers ranging from 1 mW to 1 kW. The rocket potential is measured by Langmuir probes and floating probes. Itmore » is noted that optical line emission measurements and wave measurements have also been carried out. It has been found that the rocket potential is not as high as expected from the balance with ionospheric plasma but that it is strongly affected by the plasma produced by the emitted electron beam and returning electrons.« less

  • The physical and technological concepts and barriers which are important for pulsed fusion of pellets using relativistic electron beams or lasers are discussed. Recent numerical calculations of pellet dynamics are given for the two cases in order to illustrate the similarities that exist and to indicate the significant differences which can be utilized in the spatial and temporal scale of the implosions. These calculations specify the experimental parameter regime which must be achieved, with input energy ranging as low as a few hundred kilojoules in the case of electron beams and a few kilojoules in the case of lasers; powermore » densities in the two cases tend to be comparable. An assessment of current technology, including some new results for electron beam pumped lasers, is then made for comparison. The remaining physical problems and the solutions required for achievement of fusion break-even experiments are discussed. (auth)« less
