“…In 2021, a method based on the Reactive Co-evaporation and Cyclic Deposition Reaction (RCE-CDR) of Cerium Oxide (CeO2) was proposed for CCs from STI Inc. to form the CFD layer (Ag/CeO2/REBCO) [13]. Unfortunately, the reactivity of the CeO2 with the REBCO at the interface during the REBa2Cu3O7-δ oxygen annealing process [14]- [16], led to a drastic degradation of the superconducting properties [13]. One year later, another method using the Chemical Solution Deposition (CSD) of amorphous Yttrium Oxide (Y2O3) was successfully tested on THEVA GmbH CCs to form a CFD structure Ag/Y2O3/REBCO.…”

The Current Flow Diverter (CFD) is an established concept that has proven to effectively reduce the probability of destructive hot spots by boosting the normal zone propagation velocity (NZPV) in commercial REBa2Cu3O7 (REBCO; RE= Rare Earth) coated conductors (CC). However, incorporating the CFD concept requires finding a scalable method that is also compatible with the already established R2R fabrication process used by CC manufacturers. This study presents a new simple & cost-effective proof-of-concept technique capable of recreating the CFD architecture in commercial CCs coated with silver. The technique is based on promoting a locally controlled thin film diffusion reaction between the silver stabilizer and pure indium. Due to fast diffusion in the Ag-In system, stable Intermetallic Compounds (IMC) are formed throughout the whole thickness of the silver layer reaching the REBCO interface. The presence of Ag-In IMC in the interface safely increases the interfacial resistance (Ω-cm 2 ) by orders of magnitude, thus allowing to safely form the CFD interlayer. Silver-coated tape samples altered using this CFD-IMC have shown an NZPV increase of 5-8x when compared with pristine samples.

“…An industrially compatible method to produce CFD tapes was proposed for CCs from STI Inc. and was based on reactive co-evaporation and cyclic deposition reaction [24] of cerium oxide (CeO 2 ) as the CFD layer (Ag/CeO 2 /REBCO). However, the CeO 2 showed significant reactivity with the REBCO at the interface, leading to a drastic degradation of the superconducting properties [25]. More recently, another low-cost method using the chemical solution deposition of amorphous yttrium oxide (Y 2 O 3 ) was proposed to form a CFD trilayer Ag/Y 2 O 3 /REBCO on THEVA GmbH CCs.…”

The current flow diverter (CFD) is a known concept that has proven to effectively reduce the probability of destructive hot spots in REBa2Cu3O7 (REBCO; RE = rare earth) coated conductors (CCs) by boosting the normal zone propagation velocity. However, the implementation of the CFD concept requires additional steps in a fabrication process that is already complex and has struggled to find a simple reel-to-reel fabrication method. This work reports on the details of a fabrication route for the buffer-layers-CFD (bCFD) architecture using a solid-vapor silver sulfurization technique to tune the geometry of the metal stabilizer in the high-temperature superconductor tape. The analysis of the microstructure and superconducting properties of the Ag2S/Ag/GdBCO trilayer processed under different conditions shows how we achieved a new customized functional CC with the bCFD architecture. In DC limitation experiments, this bCFD-sulfide architecture allowed to generate an electric potential much faster than the conventional architecture (60 V s−1 vs. 1.2 V s−1) thanks to the strong enhancement of the NPZV.
