    An experimental device has been developed which exhibits the characteristics of a vertical seismometer with a long natural period, the experimental device having demonstrated periods to 20 seconds. The device achieves long-period seismometer action through magnetic field support of the mass and electronic feedback. With suitable device parameters the performance equations will be of the same form ... View full abstract»

    A description is given of a sampling oscilloscope technique in which the sampling pulse recurrence rate is not in any way synchronized with the signal waveform. The technique eliminates the need for a signal channel delay line. An experimental system which employs only semiconductor devices is described, and experimental data demonstrating the practicality of the system is presented. View full abstract»

    An instrument which is well suited for use in rocket and satellite work and is capable of measuring the ion composition of the upper atmosphere is described. The theory of operation of a Paul-type mass spectrometer is presented. A system consisting of a Paul mass spectrometer and an electron-multiplier type detector, capable of measuring ion composition, is then described. The electronic system, w... View full abstract»

    This report describes a system now in operation for the purpose of calibrating microwave noise sources at three selected frequencies in the range 8.2 to 12.4 Gc. Included are a discussion of the reference standard noise source, an error analysis of the standard source and the comparison system, and evidence of system performance. Results of measurements indicate that the excess noise ratio of a sp... View full abstract»

    A new method of measuring voltages across cavity gaps and deducing the cavity's parallel resistance is discussed. The method is based on velocity modulation of a beam of monoenergetic charged particles (electrons) from a radioactive source. The change in the line spectra of an energy-selective particle detector (a semiconductor detector), when the particles pass through the gap, is used for calcul... View full abstract»

    An attenuator calibration system is described consisting of a waveguide-beyond-cutoff attenuator operating at 31.25 Mc and electronic equipment designed for parallel-substitution, series-substitution, and heterodyne measurements. Radio-frequency power is supplied by a crystal-controlled signal generator, stabilized so that variations in the power output do not exceed 0.001 db per hour. Measurement... View full abstract»
