• ### Zero-Compensation Method and Reduced Inductive Voltage Error for the AC Josephson Voltage Standard

Publication Year: 2015, Article Sequence Number: 1400806
Cited by:  Papers (5)
| | PDF (425 KB) | HTML

In the pulse-driven ac Josephson voltage standard, the low frequency (LF) component of a drive signal increases the system complexity and induces unwanted voltages through on-chip inductances. A novel zero compensation (ZC) method for pulse-driven ac waveform synthesis is presented in this paper. A pulse train is obtained through a two-level Δ-Σ modulation and then reconstructed by replacing each ... View full abstract»

Publication Year: 2015, Article Sequence Number: 1501512
| | PDF (4036 KB) | HTML

Public protection and disaster relief (PPDR, known also as public safety mobile broadband) is becoming an important issue in several countries, and a special frequency band will possibly be allocated to this service. A 5 MHz spectrum at 809 MHz for uplink (and at 854 MHz for downlink) has been under consideration by the Australian Communication and Media Authority for this purpose. This paper pres...

• ### High-Temperature Superconducting Bandpass Filter Using Asymmetric Stepped-Impedance Resonators With Wide-Stopband Performance

Publication Year: 2015, Article Sequence Number: 1501606
Cited by:  Papers (3)
| | PDF (923 KB) | HTML

This paper presents a wide-stopband high-temperature superconducting (HTS) bandpass filter (BPF). The filter is implemented by the asymmetric stepped-impedance resonators (SIRs) with only one step discontinuity, which leads to low loss and compact size. With varied characteristic impedance ratios and length ratios, the diversity of asymmetric SIR has been studied, and the spurious resonant-mode re... View full abstract»

The capability of an all-niobium superconducting quantum interference device (SQUID) array to operate as an electrically small antenna capable of detecting radio frequency from distant sources was demonstrated. The measurements were performed in three different arrays, with each array consisting of 2400 identical cells. The intrinsic broadband characteristics of the device were confirmed by the fl...

• ### Reducing Spontaneous Emission in Circuit Quantum Electrodynamics by a Combined Readout/Filter Technique

Publication Year: 2015, Article Sequence Number: 1700410
Cited by:  Papers (6)
| | PDF (689 KB) | HTML

Physical implementations of qubits can be extremely sensitive to environmental coupling, which can result in decoherence. While efforts are made for protection, coupling to the environment is necessary to measure and manipulate the state of the qubit. As such, the goal of having long qubit energy relaxation times is in competition with that of achieving high-fidelity qubit control and measurement.... View full abstract»

• ### Analysis and Simulation of AC-Biased TES Circuits

Publication Year: 2015, Article Sequence Number: 2101916
Cited by:  Papers (1)
| | PDF (1922 KB) | HTML

We systematically study the analysis and simulation of ac-biased superconductor transition-edge sensor (TES) circuits. In these ac-biased circuits, the current and voltage of the TES experience large swings in both directions, and small-signal analysis around a dc steady state does not apply. To understand their electrical and thermal behavior, we rely on concepts and techniques from radio-frequen... View full abstract»

• ### Galactic Distance Measurement System Design Using a High-$T_c$Josephson Junction Array for RF Burst Detection in Space

Publication Year: 2015, Article Sequence Number: 2401404
| | PDF (386 KB) | HTML

A design of a galactic RF distance measuring system based on a Josephson junction array is presented. The system can be used to measure the approximate distance to the origin of a radio burst in space, by measuring the frequency dispersion of the burst radiation and calculating the dispersion measure, which is then used to calculate the approximate distance to the source. The designed system can b... View full abstract»

This simulation explores the effects of insulation properties on quench propagation in ReBa2Cu3Oδ-7-based coils. At present, superconducting magnets primarily use insulators that are electrically and thermally insulating, for example, Kapton. Here, the impact of varying the thermal conductivity of the electrical insulation on quench behavior is reported. In particu... View full abstract»

Bulk high-temperature superconductors are being considered for use in several engineering applications, including passive magnetic bearings. These bearings, apart from being passive, i.e., inherently stable, also offer the promise of lower bearing losses; thus, they are being considered for use with flywheels for energy storage in applications related to frequency regulation and for correcting for...

| | PDF (1685 KB) | HTML

Shield-type superconducting fault current limiters (SFCLs), due to their outstanding advantages, form an important category of SFCLs. Tunable shield-type SFCL is a novel device that introduces the extra advantage of controllable fault current limitation. As different limitation currents may be required in a voltage level of the power system, the tunability characteristic, aside from the unificatio... View full abstract»

Recent advances in second-generation (YBCO) high-temperature superconducting wire could potentially enable the design of super high performance energy storage devices that combine the high energy density of chemical storage with the high power of superconducting magnetic storage. However, the high aspect ratio and the considerable filament size of these wires require the concomitant development of... View full abstract»

• ### Status Evaluation Method for SMES Used in Power Grid

Publication Year: 2015, Article Sequence Number: 5701310
Cited by:  Papers (6)
| | PDF (1216 KB) | HTML

Superconducting magnetic energy storage (SMES) is expected to be utilized in the power grid for dynamic power compensation. However, a SMES status such as magnet current (including parameters of power conditioning system) and temperature of superconducting (SC) magnet will restrict the output capability of SMES. This paper proposes a new method to evaluate SMES status, which will guarantee the dyn... View full abstract»

We fabricated 100-m-long class-MgB2 superconducting wires using an internal Mg diffusion (IMD) process. Coronene was added as a carbon source to enhance the in-field critical current properties. We prepared a coil with a 4.8-cm diameter with 12 turns from a 2.6-m wire cut from the long wire. We obtained uniform critical currents (the critical current (Ic), the critical curren...
