A portable germanium detector was used to detect gamma-ray emissions from a nuclear warhead aboard the Soviet cruiser Slava. Measurements taken on the missile launch tube indicated the presence of uranium-235 and plutonium-239-the essential ingredients of nuclear weapons. With the use of this equipment, these isotopes probably could have been identified at(More)
As the first generation of laser interferometric gravitational wave detectors near operation, research and development has begun on increasing the instrument’s sensitivity while utilizing the existing infrastructure. In the Laser Interferometer Gravitational Wave Observatory (LIGO), significant improvements are being planned for installation in ∼2007,(More)
Absorption of laser beam power in optical elements induces thermal gradients that may cause unwanted phase aberrations. In precision measurement applications, such as laser interferometric gravitational-wave detection, corrective measures that require mechanical contact with or attachments to the optics are precluded by noise considerations. We describe a(More)
Two acrylic cube phantoms have been constructed for BNCT applications that allow the depth distribution of neutrons to be measured with miniature 10BF3 detectors in 0.5-cm steps beginning at 1-cm depth. Sizes and weights of the cubes are 14 cm, 3.230 kg, and 11 cm, 1.567 kg. Tests were made with the epithermal neutron beam from the patient treatment port of(More)
Our purpose was to determine if a home-based faculty radiologist equipped with a high-resolution workstation could add new information to residents' readings on overnight computed chest images that was equivalent to the new information generated by faculty reviewers inside the hospital. Teleconferencing software was installed on home workstations for online(More)
