    The rate of production of neutrons by geomagnetically trapped protons incident on a vehicle was measured by a neutron counting system carried into the trapped radiation belt by a pod flow piggy back on an Atlas rocket on December 19, 1961. The flux of neutrons produced by radiation belt protons incident on the pod was determined to be at least 700 neutrons/(cm2 sec); the actual value depends somew... View full abstract»

    In order to estimate the magnitude of the radiation hazard presented by solar flare and Van Allen belt proton radiation, a simple spherical-shell shield geometry was chosen and physical dose calculatved as a function of shell thickness. Both point-target and body-phantom definitions of dose were used to define the primary particle dose. The secondary particles formed in the shield are shown to con... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1212 KB)

    The damage by radiation that can be expected during the storage of hydrogen-bonded propellants in outer space is analized in terms of the available data on radiation levels. On this basis, the alternatives of storing the propellants as liquids or as solids, at low temperature, are discussed, and account is taken of recent results on their thermal behaviour obtained at this Laboratory. Vitreous sta... View full abstract»

    Circuitry has been designed and constructed which is able to analyze and reproduce accurately the slope and pulse height at various points along a rapidly changing signal which occurs only once. The signal is analyzed at 10-nanosecond intervals. This circuitry is also able to sense a zero slope per unit time and in this mode it can be used as a multichannel pulse height analyzer with a dead-time w... View full abstract»

    The most efficient use of telemetry channels is always a paramount problem of space flight projects. Monitoring radiation fields in space often requires coverage of large ranges of count rate which, if count rate meters are to be used, means either a decrease in resolution due to coverage of the entire range with one rate meter or use of several telemetry channels if several different rate meters ...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1815 KB)

    In the design of particle accelerators, magnets are sometimes used to bend the paths of charged particles in linear accelerators for focusing and defocusing purposes. These magnets, in the present case, are known as quadrupoles. Their design hinges on the solution of certain mathematical expressions of particle trajectories. A computer of the analog type was constructed to solve the equations and ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1752 KB)

    Improvements in detector resolution and increases in the sophistication of nuclear experiments have placed an entirely new emphasis on linear amplifier design. Just a few years ago it was necessary to have specialized amplifiers to deal with each specific problem. The lack of flexibility now plaguing most existing linear pulse amplifying systems is often quite annoying to the user. Invariably, the... View full abstract»

    The design of the nuclear instrumentation system for the Pluto series of nuclear ramjet test reactors is an attempt to provide a very flexible nuclear sensing system that will be adequate for Tory II-C and following test reactors. The nuclear detectors will be exposed to the leakage neutron flux from the reactor during operation. Since the leakage flux is proportional to reactor power, the neutron... View full abstract»

    This paper describes a method for predicting transistor reliability as a function of nuclear radiation exposure, through the use of the Weibull distribution. Graphical plots of seven different types of transistors show ac gain degradation as a function of integrated neutron exposure. The plots on Weibull graph paper are extended to include probability of failure to 0.1 and 0.01 percent. The graphs... View full abstract»

    The effects produced by different types of nuclear radiation can be compared by making use of the available information on radiation-effects mechanisms. One can separate radiation-effects manifestations into three categories: transient radiation effects, which are due to excited and ionized electrons; displacement radiation effects, which are manifestations of atoms displaced from their normal lat...

    The electrons and protons of the Van Allen Belt cause radiation damage to silicon solar cells which results in a gradual reduction of the power output of solar power plants on satellites passing through the Belt. The study of the radiation damage caused by monoenergetic electrons and by monoenergetic protons of various energy indicates that N on P solar cells are substantially more radiation resis...

    Space radiation can cause damage to satellite electronic systems. The amount of damage can be determined if the radiation induced component changes are known and if the behavior of the electronic system as a function of component changes can be determined. By relating space radiation damage to neutron damage, a large amount of semiconductor device data becomes available for satellite damage predic... View full abstract»

    Collisions involving electrons, photons, and atomic systems are important in upper atmospheric and astrophysical phenomena and in the exploration of space. Some of these types of reactions are enumerated and described. Examples are given of their significance with respect to diffusion in the atmosphere; radio communications and radar tracking; the excitation and study of the airglow and aurorae; t...

    The acceleration of a gas undergoing ionization in a crossed electric-magnetic field leads to the formation of current sheets similar to those observed in coaxial plasma guns. The dynamics of such sheets is of great interest to workers in plasma physics in view of their application to controlled thermonuclear fusion experiments and to space propulsion. In the present paper a detailed mapping of th... View full abstract»

    Experiments are reviewed which measure the three-body volume recombination coefficient of neutral nitrogen atoms in nitrogen gas making use of an electron spin resonance (ESR) technique to determine the atomic concentration. The nitrogen atoms were created in an electrodeless discharge and were carried to the ESR detector by a stream of flowing gas. The temperature dependence of the atomic recombi... View full abstract»

    The propagation of electromagnetic radiation from 500 to 4200 Mc in a coaxial cage transmission line passing through a cylindrical discharge chamber is investigated experimentally. Measurements were conducted in argon, helium, and nitrogen gas at pressures between 0.09 mm Hg and 2 mm Hg for a discharge-electromagnetic radiation interaction length of 30.48 cm. The results are compared with theory u... View full abstract»
