摘要： A superconductor filter is stored in a hermetic filter case so that electrical connection can be provided between the superconductor filter and the outside of the hermetic filter case. The hermetic filter case is stored in a hermetic outer case so that electrical connection can be provided between the superconductor filter and the outside of the hermetic outer case and so that air/gas flow through pipes can be implemented between the inside of the hermetic filter case and the outside of the hermetic outer case. The hermetic filter case and the hermetic outer case are evacuated into vacuum, and the superconductor filter is cooled below its critical temperature. After the superconducting state of the superconductor filter could be observed, gas that does not deteriorate or react with the superconductor filter is gradually packed in the hermetic filter case and thereby the dielectric constant around the superconductor filter is raised from the dielectric constant of vacuum. The amount of the gas packed in the hermetic filter case is increased/decreased while observing transmission characteristics (center frequency etc.) of the superconductor filter, until desired transmission characteristics are obtained. Thereafter, the hermetic filter case is hermetically sealed so that the amount of the gas in the hermetic filter case will thereafter be fixed.

摘要： A two-dimensional array of Josephson junctions is used as a high-frequency oscillator capable of emitting coherent power of predetermined frequencies since the geometry of the two-dimensional array allows the individual Josephson junctions to phase lock at predetermined frequencies. The array is controlled at a given voltage and excited by the application of DC current through the array, in effect providing a rapidly tunable DC-to-AC converter at GHz and THz frequencies. The oscillator operates without the application of external high frequency signals or a connection to a cavity resonator. Load matching and other adjustments can be made by selecting the appropriate number of Josephson junctions in the array, selecting a damping factor which determines non-hysteretic operation, adding resistive shunts or a superconducting ground plane. The two-dimensional array used as an oscillator has advantages over one dimensional arrays in that voltage equalization from junction-to-junction occurs naturally so that phase locking is less likely to be affected by non-identical junctions, greater power output can be realized, an output having a narrower line width is produced and impedance matching is relatively easy.
摘要翻译：使用约瑟夫逊结的二维阵列作为能够发射预定频率的相干功率的高频振荡器，因为二维阵列的几何形状允许各个约瑟夫逊结以预定频率锁相。该阵列被控制在给定的电压并且通过施加直流电流通过阵列而被激励，实际上提供了在GHz和THz频率下的快速可调DC-AC转换器。振荡器在不施加外部高频信号或连接到空腔谐振器的情况下工作。可以通过选择阵列中适当数量的约瑟夫逊结，选择确定非迟滞操作的阻尼因子，添加电阻分流器或超导接地平面来进行负载匹配和其他调整。用作振荡器的二维阵列具有超过一维阵列的优点，因为从结到结的电压均衡自然发生，使得相位锁定不太可能受到不相同的结的影响，可以实现更大的功率输出，产生具有较窄线宽的输出，并且阻抗匹配相对容易。

摘要： A multimode oscillator is disclosed, comprising an array of interconnected oscillator elements distributed over at least two dimensions. The oscillator elements include a grid or network of impedance elements. Three or more inductive (capacitive) elements may radiate from each junction point in the grid, and a capacitive (inductive) element may be shunted to ground from each junction point. Other arrangements of impedance elements are also possible. The multimode oscillator may be either passive or active. In a passive oscillator, the oscillations are not sustained but rather are damped by the resistance elements and other losses in the oscillator. A passive oscillator may be excited into various simultaneous modes of oscillation by coupling the output of a white noise generator, or some other white signal source, to the multimode oscillator. The resulting oscillations are picked up and analyzed as to their frequency components. A bank of filters may be employed to separate the various frequency components. Digital logic circuits may be employed to analyze the signals from the filters. Sustained oscillations may be produced in a passive multimode oscillator by providing feedback means between the output and input of the oscillator. Such feedback means may include an amplifier and a nonlinear inductive element or some other nonlinear element which makes it possible to sustain a number of different modes of oscillation simultaneously. An active multimode oscillator employs active elements capable of sustaining the oscillations in the oscillator. Such active elements may include various negative resistance elements such as tunnel diodes. The multimode oscillator may utilize superconductive elements which may be arranged to form a superconductive grid or network to provide an array of inductive elements. The capacitive elements may be provided by the distributed capacitance between the superconductive grid and a superconductive ground plate or surface. The superconductive multimode oscillator may be either passive or active. Active elements may be provided by superconductive tunneling through thin barrier elements between portions of the superconductive grid and the ground plate. The active tunnel elements may also be radiation sensitive.

摘要： An electronic clock has a single Josephson junction connected in parallel to a resonant circuit, which is a delay line with a matching resistance at the input end to provide series termination. The opposite end of the delay line is an open end to reflect pulses, and the pulse transit time on the line determines the clock rate. A zero crossing detector is provided to initiate the clock operation when an input signal rises above a given threshold, and a reset circuit is included to turn off the clock when the input signal falls below this threshold. A flip-flop circuit allows the clock to be turned on by alternate initiating signal pulses. A modification includes a pulse rejuvenating circuit at the end of the delay line to offset pulse degradation. All of the circuits are fabricated with Josephson junction elements, and the zero crossing detector, reset circuit, flip-flop circuit and pulse rejuvenator circuits include dc-SQUID's. The clock is capable of operation at frequencies up to 100 GHz and can sample input single frequencies as high as 15 GHz.

摘要： A superconducting oscillator for generating millimeter and infrared radiation and a method for fabricating these oscillators. A Josephson junction (weak link or tunneling juntion) is located between electrodes which furnish DC current to the junction and also define a resonant cavity for electromagnetic radiation from the junction. Thus, an internal cavity is provided and increased power outputs over a wide frequency range are possible. The oscillator is produced by spark erosion between the electrodes at liquid helium temperatures, which forms a very small junction and cavity resonator.

摘要： An improved SNS supercurrent device comprises a pair of superconductive regions, a relatively thick insulative region contiguous with and separating the superconductive regions from one another, and a normal metal region contiguous with both superconductive regions. The insulative region is of sufficient thickness to prevent substantial supercurrent tunneling therethrough when a current source is connected between the superconductive regions. Consequently, current, following the path of least resistance, flows in a path including the normal metal region. The junction defined by the normal metal region has a significantly reduced cross-sectional area which in turn means the device has lower critical supercurrents and higher resistances than heretofore attainable in SNS structures.

摘要： The fluxon oscillators for producing electromagnetic radiation having a wavelength shorter than the shortest radio waves, but longer than the longest infrared radiation, may comprise two closely spaced superconductive ring-shaped members having a ring-shaped Josephson junction barrier therebetween capable of supporting the tunnelling of superconductive electrons across such barrier, a source of magnetic flux for initially producing at least one fluxon in the barrier, a power supply for producing an electrical biasing current between the superconductive members and across the barrier for causing movement of the fluxon along and around the ring-shaped barrier in a closed path, and a plurality of centers to produce enhanced superconductive electron current across the barrier, such centers being spaced around the ring-shaped barrier for causing cyclical variations in the velocity of the fluxon and thereby causing the radiation of electromagnetic energy at a frequency corresponding to the frequency of such cyclical variations. Such centers may comprise localized microshorts or weak links which are conductive to normal tunnelling electrons and exhibit enhanced tunnelling by superconductive electrons. Such weak links may be made of a normally conductive metal, such as copper, silver or gold. The superconductive members may be in the form of superimposed ring-shaped layers with the barrier sandwiched therebetween, or in the form of concentric inner and outer ring-shaped layers, with the barrier being disposed between the edges thereof. Such centers may also be provided by photoconductive material in the barrier, illuminated by a pattern of illumination.
