A comprehensive analysis of reflex klystrons is developed by considering the electrons as particles acted upon by forces which modify their motion. The analysis is similar to earlier explanations of electron bunching in a field-free drift space and predicts a similar current distribution when bunching takes place in a reflecting field. The effect of the bunched electron beam is treated qualitatively by considering the effect of the beam admittance upon a simple equivalent circuit. A quantitative ...

This paper presents a new principle in wide-band amplifier design. It is shown that, by an appropriate distribution of ordinary electron tubes along artificial transmission lines, it is possible to obtain amplification over much greater bandwidths than would be possible with ordinary circuits. The ordinary concept of "maximum bandwidth-gain product" does not apply to this distributed amplifier. The high-frequency limit of the distributed amplifier appears to be determined by the grid-loading effects. ...

The theory, design, and some experimental results relative to linear electron accelerators are discussed. It is shown that, though the orbits are unstable, this instability is so small as to be negligible in general, provided the electrons are injected at relativistic velocities. Likewise, space-charge spreading may be neglected. The optimum loading design is found for various types of power feeds and curves are given by means of which any design may be evaluated. A number of illustrative cases ...

A traveling-wave tube designed to operate as a frequency multiplier (twfm) is described, together with experimental results. The tube employs two helices in cascade, the output helix being a dispersive forward-wave helix operating at S band. A wide range of input frequencies can be used, and the dispersive character of the output helix permits the selection of a particular harmonic by voltage tuning of the helix. The experimental tube was designed to operate with an input frequency range of 0.5 to ...

In the use of the impedance (Q-circle) method of measuring the cavity Q values, the presence of losses in the coupling network (between the cavity and the available external terminals) is usually neglected. If appreciable losses are present this simplification is not justitied, and its use can lead to significant errors. The losses in any coupling network can be described by means of an equivalent canonical circuit containing a series and a shunt resistor. The losses due to the series element are ...

Residual gas within the envelope of an electron tube forms positive ions by electron collision. Ordinarily these ions are quickly lost to the cathode; however, if they can be held within the beam space, the spreading due to the space charge of the beam might be considerably reduced. A "trapping" electrode, with an appropriate positive potential, placed at the cathode end of the drift tube was believed sufficient to affect trapping. Since this simple method was first proposed, attempts to make the ...

Values of R/Qf or re-entrant resonators are given for configurations for which neither the coaxial-field nor the radial-field approximations are valid. The values are calculated by net point methods, and agree well with experimental values obtained by perturbation methods. Some errors arising from the finite dimensions of perturbing plungers are also discussed.

The coaxial directional coupler of the Bethe-Hole type consists of two coaxial transmission lines crossed at an angle of 60° and coupled by a single circular hole. It has been previously shown that this device should have perfect directivity at any wavelength, provided that (a) the diameter of the coupling hole is small compared with λ/8, (b) the thickness of the hole is infinitesimal, and (c) only the dominant TEM mode is allowed to exist in the transmission lines. These requirements can easily be ...

A six-arm waveguide structure is described which is a true microwave equivalent of a Wheatstone bridge. A theoretical analysis of the equivalent circuit of the device has been made, using the symmetry properties of the structure. The resulting relation among the admittances of the various arms is exactly that of a Wheat-stone bridge with shunting susceptances across each pair of terminals. A device of this sort for use at 10 cm has been built and tested, and was found to behave as predicted. With ...

This paper describes a type of resistance-capacitance-tuned oscillator which operates with a single tube. A three- or more mesh phase-shifting network is connected between the output and input of an amplifier tube. When the gain of the amplifier is adjusted either manually or by an automatic-volume-control circuit barely to maintain oscillation, almost pure sine-wave output is obtained. Variations in the basic circuit have been analyzed and design formulas are included in this paper. Experimental ...

To obtain a clearer insight into the design of velocity modulated tubes, a more complete understanding of the bunching process is required. A theory, to be useful in the design of high power tubes, should include the effects of space charge and large signals. Although such a theory has not yet been developed, a small signal theory, due to Feenberg, including the effects of space charge, has been obtained for some useful physical configurations. This paper deals with the experimental confirmation ...

I first met Russell Varian in 1939 on a stairway landing in the Stanford University Physics Building. I had just been hired as a part-time research associate on the new Klystron Project at a then munificent $90 per month, and was going upstairs to meet the Varians and their small staff. I had heard of the invention of this new electron tube that could generate centimeter waves, but I did not know how it worked, and indeed I had never even seen one. Thus, when I stopped and introduced myself to Russ, ...

The following paper describes and analyzes mathematically a new principle in amplifier design. It is shown how noise, phase shift, frequency distortion, etc., can be largely eliminated by use of the "balanced feed-back principle" without reduction of the over-all gain of the amplifier. By means of balanced feedback the linear range of an amplifier using ordinary receiving-type tubes has been extended from an upper limit of 600,000 up to 2,500,000 cycles. Theoretical and experimental results were ...

This paper describes the development of three practical, sealed-off, tunable klystrons intended for operation in the region of 1 to 2 megw at the S, L, and X radar frequency bands. These tubes are an outgrowth of the previous development at Stanford of a 30-megw S-band klystron in conjunction with the billion-volt linear electron accelerator program. Similar design principles apply to all of these tubes, but the three smaller klystrons described make use of cavity tuning methods appropriate to the ...
