Available in PDF, EPUB and Kindle. Book excerpt: During the 1962 high altitude test series, measurements of the energy spectra of the neutrons from three devices were made by the space physics group of the Los Alamos Scientific Laboratory. The explosions occurred at high altitudes, above the atmosphere, and near Johnston Island. The measurements were made with detectors flown from Kauai, Hawaii to above the atmosphere, on two-stage Nike-Apache rockets. The range between the explosion and the detector packages was about 1300 km. For each of the tests, two moderated fission detectors and two plastic fluor detectors were flown, except that on the third test, an extra fluor detector which had been recovered from the ocean, was also flown. Useful records were obtained for every rocket flown, which makes thirteen neutron spectrum measurements recovered out of thirteen attempts. Although the prime objective of the experiments was to measure the neutron energy spectra, a secondary objective was accomplished in the field of time-of-flight measurements on the resonance structure of various nuclides. Since the experiments were not designed specifically to make cross section measurements, the results are not as detailed as they could be, but some useful results were obtained.

Download or read book Nuclear Physics written by National Research Council and published by National Academies Press. This book was released on 1999-03-31 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dramatic progress has been made in all branches of physics since the National Research Council's 1986 decadal survey of the field. The Physics in a New Era series explores these advances and looks ahead to future goals. The series includes assessments of the major subfields and reports on several smaller subfields, and preparation has begun on an overview volume on the unity of physics, its relationships to other fields, and its contributions to national needs. Nuclear Physics is the latest volume of the series. The book describes current activity in understanding nuclear structure and symmetries, the behavior of matter at extreme densities, the role of nuclear physics in astrophysics and cosmology, and the instrumentation and facilities used by the field. It makes recommendations on the resources needed for experimental and theoretical advances in the coming decade.

Download or read book Radioisotope Power Systems written by National Research Council and published by National Academies Press. This book was released on 2009-08-14 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spacecraft require electrical energy. This energy must be available in the outer reaches of the solar system where sunlight is very faint. It must be available through lunar nights that last for 14 days, through long periods of dark and cold at the higher latitudes on Mars, and in high-radiation fields such as those around Jupiter. Radioisotope power systems (RPSs) are the only available power source that can operate unconstrained in these environments for the long periods of time needed to accomplish many missions, and plutonium-238 (238Pu) is the only practical isotope for fueling them. Plutonium-238 does not occur in nature. The committee does not believe that there is any additional 238Pu (or any operational 238Pu production facilities) available anywhere in the world.The total amount of 238Pu available for NASA is fixed, and essentially all of it is already dedicated to support several pending missions-the Mars Science Laboratory, Discovery 12, the Outer Planets Flagship 1 (OPF 1), and (perhaps) a small number of additional missions with a very small demand for 238Pu. If the status quo persists, the United States will not be able to provide RPSs for any subsequent missions.
