    This paper was written to present the subject of magnetic amplifiers to those scientists and engineers who have not had an opportunity to observe the progress which has taken place in this field. No detailed technical discussions have been attempted and many aspects of magnetic amplifier operation and applications are only briefly mentioned. The basic operation, along with certain fundamental circ... View full abstract»

    This paper presents theoretical and experimental results concerning the "M Carcinotron." In particular, the influence of space charge has been considered, thereby permitting an explanation for the measured values of starting current, the influence of the coupling impedance on efficiency and the existence of parasitic oscillations. The "rising sun effect" which should be present in these tubes, as ... View full abstract»

  • Power Flow in Electron Beam Devices

    Publication Year: 1955, Page(s):425 - 427

    This paper discusses power flow in devices in which electrons are constrained to move in the z direction only. Besides the electromagnetic power flow given by Poynting's vector, there is a kinetic power flow per unit area in the z direction. In a linear system equivalent to the electron beam at low levels of operation this power flow is PR = ---(- J0+J)(u02+2u0v). Here -J0 and J are the dc and ins... View full abstract»

  • The Effective Surface Recombination of a Germaniun Surface with a Floating Barrier

    The effect of heavily doped (alloyed) p-type and n-type surface layers on n-type base, and of metallic plating on n-type base, on the surface recombination velocity s has been computed on the basis of one-dimensional junction theory. The results indicate that s should be of the order 1 cm/sec for the heavily doped surfaces, and several thousand cm/sec for the electroplated surface. The low s comes... View full abstract»

  • A Chart for Analyzing Transmission-Line Filters from Input Impedance Characteristics

    Filter calculations become difficult when network elements consist of transmission-line sections, since transcendental equations are involved. It is the purpose of this paper to describe the application of familiar impedance methods and Smith chart techniques which simplify many of these calculations. A chart is developed by means of which the most important characteristics of a filter may be read... View full abstract»

  • Concerning the Noise Figure of a Backward-Wave Amplifier

    Publication Year: 1955, Page(s):444 - 449
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1362 KB)

    The noise figure of a traveling-wave amplifier has been derived as a function of circuit loss and space charge. The minimum-obtainable noise figure of the backward-wave amplifier is shown to be the same as the minimum-obtainable noise figure of the forward-wave amplifier, i.e., about 6 db. The noise figure of an ordinary backward-wave amplifier has been measured as a function of gain. The calculat... View full abstract»

  • The Nature of the Uncorrelated Component of Induced Grid Noise

    Publication Year: 1955, Page(s):449 - 454
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1547 KB)

    An investigation of induced grid noise in vacuum tubes has been made. It was found that the uncorrelated component of grid noise can be explained in terms of electrons elastically reflected from the plate of the tube. Experimental and theoretical justifications of this explanation are presented. The accuracy of methods for predicting grid noise from measurements of input admittance is affected bec...

  • On the Possibility of Amplification in Space-Charge-Potential-Depressed Electron Streams

    Hahn-Ramo theory is used to derive a characteristic wave equation for an electron stream whose single-valued velocity is a function of spatial co-ordinates. A means of solving this equation is found, for the particular case of two-dimensional Cartesian coordinates. A specific, but practical, linear velocity distribution is assumed. It is shown that for several types of boundary conditions, the onl... View full abstract»

  • RLC Lattice Transfer Functions

    Cited by:  Papers (2)

    Necessary and sufficient conditions that a real rational function be the transfer function of an RLC symmetric lattice are derived. The range of allowable values of the multiplicative factor (which determines the gain level) in the transfer function is determined and an algorithm for its calculation is given. While the zeros of the transfer function may be anywhere in the complex number plane, the... View full abstract»

  • Modes and Operating Voltages of Interdigital Magnetrons

    Methods have been discussed for obtaining a desirable frequency spectrum of the modes of an interdigital resonator, so that it may be possible to get useful operation in more than one mode. The consequences of phase reversal at certain locations in the anode, in the case of nonzero order modes, have been analyzed, together with the effects of phase-shifting fingers. Experimental results have been ... View full abstract»

  • Measurement of Minority Carrier Lifetime and Surface Effects in Junction Devices

    Publication Year: 1955, Page(s):477 - 483
    Cited by:  Papers (112)  |  Patents (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1481 KB)

    The characteristics of junction devices are influenced to a considerable degree by the lifetime of the minority carriers. Accordingly, methods for the measurement of this quantity are of considerable importance. Methods have been described for the measurement of the lifetime of minority carriers when these carriers are produced within the volume of a semiconductor. When the minority carriers are i...
