MOCVD of coated conductors on RABiTS

La2Zr2O7 single buffer layer for YBCO RABiTS coated Conductors

Chemical deposition methods like MOD and MOCVD are promising approaches for coated conductors (CCs) due to their reduced cost and easy scaling. High quality La2Zr2O7 (LZO) buffer layers were prepared by MOD on Ni-5%at.W (NiW) RABiTS and subsequent YBCO layers (450 to 800 nm thick) were deposited by pulsed injection MOCVD, leading to a simple low cost architecture NiWRABiTS/LZOMOD/YBCOMOCVD.

AC losses in coated conductors

Future use of coated conductors in electric power applications like transmission cables, transformers or fault current limiters is sensitive to the amount of dissipation in the AC regime. This paper analyses factors controlling AC loss of coated conductors in typical configurations: the self-field case when transport current generates the magnetic field, and the case of AC applied field where t...

Influence of neutron irradiation on high temperature superconducting coated conductors

High temperature superconductors (HTS) might be applied for the magnets in a next step fusion device. The magnets could operate in the temperature range of liquid nitrogen or slightly below. Apart from the special requirements on the mechanical properties, the conductors will be exposed to radiation. We examine the influence of neutron irradiation on coated conductors. These conductors were irr...

Near-adiabatic quench experiments on short YBa2Cu3O7− coated conductors

Minimum quench energy and normal zone propagation velocity are measured on short YBa2Cu3O7− coated conductors in self-field at temperatures ranging from 40 to 77 K. The sample is cooled via a cryocooler with a cryostat pressure of 10−4 Pa, creating a nearly adiabatic environment. A normal zone is created by pulsing a heater that is attached to the sample surface with a thin layer of alumina-fil...
