Faraday Factory Japan (FFJ) has established the world’s largest facility for manufacturing of 2G HTS tape and is ready to further expand production capacity with anticipated demand growth. At present, the factory capacity exceeds 1,000 km of 12 mm wide tape per year (or 3,000 km of 4 mm wide tape).
Over more than a decade on the 2G HTS tape market, the selling price of FFJ HTS tape halved...
In the initial design phase of the Future Circular Collider (FCC), concerns arose regarding high beam impedance coupling of the inner walls, posing a risk of destabilizing the particle beam due to high image current. To address this challenge, a collaborative effort with CERN led to the development of a REBCO coating process that preserves their low surface impedance [1].
This endeavor...
With the progress of applications such as compact nuclear fusion reactors and power devices using high temperature superconducting wires, the need for REBCO coated conductors (CCs) is increasing, and manufacturing of the REBCO CCs is shifting to mass production stage. On the other hand, the combination of process parameters in the REBCO CC manufacturing is diversified, and it is still...
Iron-based superconductors (IBS) are promising candidates for high-field applications not only because of their advanced superconducting properties but also due to the cost-effective powder-in-tube method. While IBS tapes have achieved high critical current density (J$_c$) above J$_c$(4.2 K, 10 T)=2×10$^5$ A/cm$^2$, improving the J$_c$ of round wires has been challenging. Here, we fabricated...
Within the framework of the study of future high-energy particle colliders, high-field (15-16 T) Nb3Sn magnets are being developed. These magnets are usually impregnated using epoxy resin with glass fiber to provide electrical insulation and mechanical support to the conductor.
However, several phenomena are often observed: first, the high-stress conditions applied during pre-load, cool-down,...
REBCO superconducting coils for aircraft propulsion motors boost magnetic flux density and output power which in turn improves the power-over-weight ratio. However, self-heating which can be due to either an AC current or a short-circuited DC voltage could cause thermal quench in HTS stator coils. Therefore, it is needed to analyze the complex interactions between electromagnetic phenomena and...
High costs have hindered the practical use of REBCO coated conductors, despite their promising properties for a wide range of applications. A potential way for lowering the costs is by increasing the growth rate of the superconducting material while keeping high critical current density values [1]. The novel high throughput growing method Transient Liquid Assisted Growth (TLAG) [2,3] is...
CERN is developing high-current superconducting links (SC-Links) to power the superconducting magnets of the High Luminosity upgrade of the Large Hadron Collider (HL-LHC). These SC-Links consist of up to 120 m long magnesium-diboride (MgB2) cables containing multiple insulated circuits and feature a total DC capability of up to 120 kA at a temperature of 20 K. The MgB2 cables are spliced on...
