• ### Optimization of the Stress Distribution of Helical Coils With a Cable-in-Conduit Configuration

Publication Year: 2011, Page(s):3494 - 3500
| | PDF (641 KB) | HTML

Virial-limit coils for application to magnetic confinement nuclear fusion devices are hybrid helical coils that level electromagnetic stresses. In past research, a possibility that a large bending stress is caused in helical coils made of a cable-in-conduit configuration (CICC) was pointed out. In this paper, we analytically evaluated the stresses of helical coils made of CICC by modeling them as ... View full abstract»

Thermal stability and protection in the event of quench are key issues in the design of superconducting magnets. Quench development and propagation strongly depend on the conductor characteristics and the magnet configuration. An adequate quench protection method must maintain both the peak temperature and the peak voltage during the event within acceptable limits. This paper presents quench model... View full abstract»

• ### Numerical Field Calculation in Support of the Hardware Commissioning of the LHC

Publication Year: 2011, Page(s):3509 - 3513
| | PDF (391 KB) | HTML

The hardware commissioning of the Large Hadron Collider required the testing and the qualification of the cryogenic and vacuum system, as well as the electrical systems for the powering of more than 10 000 superconducting magnets. Non-conformities had to be resolved within a tight schedule. In this paper, we focus on the role that electromagnetic-field computation has played during hardware commis... View full abstract»

• ### Viable Inductive Superconducting Fault-Current Limiters Using Autotransformer-Based Hybrid Schemes

Publication Year: 2011, Page(s):3514 - 3522

| | PDF (1098 KB) | HTML

Among superconducting fault-current limiters (FCLs), the inductive type has some distinctive merits such as large design flexibility due to the turn ratio, isolation between a current-limiting device and a power transmission line, and low heat losses. This paper highlights the future perspective for an inductive-type superconducting fault-current limiter (LSFCL) by using an autotransformer (AT) in... View full abstract»

• ### A Homopolar HTSG Topology for Large Direct-Drive Wind Turbines

For offshore wind energy, there is a trend toward larger wind turbines. The increased mass of a power-takeoff system increases the installation cost of the turbine. Direct-drive superconducting generators have the potential to reduce the installation cost of wind turbines. For a successful entry to the offshore-wind-energy market, a high-temperature superconducting generator should be as reliable ... View full abstract»

| | PDF (1242 KB) | HTML

A numerical model based on the critical-state approximation and on a magnetic-energy minimization procedure is presented to simulate the levitation of a system composed of two isolated infinitely long superconductors levitating over permanent-magnet guideways. Three different sets of magnetic guideways are simulated and compared with experimental tests of a linear superconducting magnetic bearing ... View full abstract»

• ### Numerical Study of Josephson Junction Qubits With an Unharmonic Current–Phase Relation

Publication Year: 2011, Page(s):3541 - 3547

| | PDF (988 KB) | HTML

This paper numerically analyzes the influence of second harmonics on the characteristics of Josephson junction quantum bits (qubits). It is shown that the splitting of energy states of phase qubits is sensitive to energy scale and unharmonicity parameters. On the other hand, for charge qubits, the expectation value of the Cooper-pair number is not affected by the inclusion of unharmonicity paramet... View full abstract»

The Laboratory for Applied Superconductivity of the Federal University of Rio de Janeiro (LASUP) has been developing a superconducting magnetic levitation urban train named MagLev-Cobra. It is a kind of light rail vehicle where the conventional wheel-rail track is substituted by a rail of Ne-Fe-B magnets and carbon steel interacting with superconductor bulks installed in the vehicle to promote lev...

• ### Slip–Stick Mechanism in Training the Superconducting Magnets in the Large Hadron Collider

Publication Year: 2011, Page(s):3555 - 3560

| | PDF (793 KB) | HTML

Superconducting magnets can exhibit training quenches during successive powering to reaching nominal performance. The slip-stick motion of the conductors is considered to be one of the mechanisms of training. In this paper, we present a simple quantitative model where the training is described as a discrete dynamical system matching the equilibrium between the energy margin of the superconducting ...

• ### Reliability Evaluation of Distribution Network With DG Considering the Reliability of Protective Devices Affected by SFCL

Publication Year: 2011, Page(s):3561 - 3569

| | PDF (710 KB) | HTML

This paper proposes a reliability model for a superconducting fault current limiter (SFCL), which is a new alternative in limiting the fault current recently increasing in a network. An evaluation technique for distribution reliability that uses the improved failure rate of all protective devices in a network, depending on the location of the SFCL, is also proposed. As a result, it is expected tha... View full abstract»
