The effects of superconductor-stabilizer interfacial resistance on quench of a pancake coil made out of coated conductor
G. A. Levin, W. A. Jones, K. A. Novak +1
We present the results of numerical analysis of normal zone propagation in a stack of coated conductors which imitates a pancake coil. Our main purpose is to det…
Use of 2G coated conductors for efficient shielding of DC magnetic fields
J. -F. Fagnard, M. Dirickx, G. A. Levin +3
This paper reports the results of an experimental investigation of the performance of two types of magnetic screens assembled from YBa2Cu3O7-d (YBCO) coated conductors. Since effec…
Stability and normal zone propagation speed in YBCO coated conductors with increased interfacial resistance
George A. Levin, Paul N. Barnes, Jose P. Rodriguez +2
We will discuss how stability and speed of normal zone propagation in YBCO-coated conductors is affected by interfacial resistance between the superconducting film and the stabiliz…
AC-Tolerant Multifilament Coated Conductors
G. A. Levin, P. N. Barnes, N. Amemiya
We report the magnetization losses in an experimental multifilament coated conductor. A 4 mm wide and 10 cm long YBCO coated conductor was subdivided into eight 0.5 mm wide filamen…
Coupling losses and transverse resistivity of multifilament YBCO coated superconductors
M. Polak, L. Krempasky, E. Usak +6
We studied the magnetization losses of four different types of filamentary YBCO coated conductors. A 10 mm wide YBCO coated conductor was subdivided into 20 filaments by laser cutt…
Concept of Multiply Connected Superconducting Tapes
G. A. Levin, P. N. Barnes
The possibility of a substantial reduction of weight and size of electrical generators is the main incentive behind the effort to develop superconducting armature windings based on…
