 | In this work, experiments with the stacked Blumlein prototype pulsers were conducted under different conditions of operation at power levels bypassing 100 MW. Special attention was placed on broadening of the current channels in the avalanche photoconductive switch in order to improve lifetime. The mechanical and semiconductor properties of amorphic diamond were employed to improve the lifetime by coating the switch cathode or anode areas or both. Issues concerning the ... |

 | Nuclear spin isomers store electromagnetic energy at densities reaching 1.3 GJ/g for shelf lives approaching centuries. One example, Hf-178 has been shown to release such stored energy when triggered by x-ray flashes at modest power levels. In this work trigger pulses were derived from a familiar x- ray source typically used in dental medicine. Subsequent experiments using tunable x-rays from the synchrotron radiation source, SPring-8 showed that the triggering was ... |

 | In this work, Several photoconductively- switched stacked Blumlein prototype were developed and successfully tested at power levels approaching 100 MW. These devices had a compact geometry and commutated by a single avalanche photoconductive switch. Special attention was placed on broadening of the switch current channels. Device longevity was tested by fabricating switch with metal or diamond coatings and by implementing different switch/electrode configurations. A significant ... |

 | Studies of the 29 possible candidates to use as the working medium of a gamma ray laser have identified the 31-year isomer of Hafnium-178 as the best. This research was aimed at the development of a production cycle for this rare substance. A major success of this work was the discovery in byproduct debris from the synthesis of medical isotopes of a quantity of this material equal to 99% of ... |

 | This project concerns the demonstration of the feasibility of the tuning and perhaps even stimulation of nuclear radiation. Theory has indicated that anti-Stokes Raman upconversion of intense but conventional long wavelength sources of radiation produced by scattering from isomeric states of nuclear excitation could lead to significant sources of tunable Gamma-radiation characterized by the natural Mossbauer widths of the lines. This would result in lines with sub-Angstrom wavelengths and widths ... |

It embodies the simplest concepts for a gamma-ray laser and not surprisingly, the greatest rate of achievement in the quest for a subAngstrom laser continues in that direction. For ruby the identification and exploitation of a band width funnel were the critical keys in the development of the first laser. There was a ... |

 | A major effect was found that had defied the constructi on of a completely satisfactory explanation in terms involving only conventional processes of incoherent excitation. It was the generation of radiofrequency sidebands on the hyperfine Moessbauer spectra of Fe57 in ferromagnetic environments. Through the application to a ferromagnetic iron foil of a magnetic field oscillating at radiofrequencies, several new spectral lines were produced in addition to the usual six hyperfine ... |

 | This report focuses upon a breakthrough recently realized along the more complex direction toward the coherent pumping of a gamma-ray laser. The intent is to mix the quantum properties of long-lived nuclear states with those able to radiate freely. In this way the metastability of an isomeric state could be switched off. The critical experiment is to show that some laboratory level of coherent input power can affect the properties ... |
