In the large-scale superfluid helium cryogenic refrigeration system, the helium cold
compressor faces the complex operating conditions of low temperature, high speed and sub …

Drilling holes in a bulk high-T c superconductor enhances the oxygen annealing and the
heat exchange with the cooling liquid. However, drilling holes also reduces the amount of …

A new approach for growing large size single domains of Y–Ba–Cu–O by a top-seeded melt-
textured growth (TSMTG) process is reported. Contrary to the commonly used TSMTG …

Active magnetic bearings and superconducting magnetic bearings were used on a high-
speed flywheel energy storage system; however, their wide industrial acceptance is still a …

Рассмотрено общее состояние работ по созданию устройств на основе
высокотемпературных сверхпроводников. Изложены результаты разработки и …

Developing of 100Kg-class flywheel energy storage system (FESS) with permanent
magnetic bearing (PMB) and spiral groove bearing (SGB) brings a great challenge in the …

We reported a modified multi-seeding approach to grow multi-seeded single grain Y–Ba–Cu–
O (YBCO) bulk for overcoming the problem in conventional multi-seeding method, ie the …

It is well known that a fine and homogeneous distribution of Y 2 BaCuO 5 (Y211) phase
particles in single-grain Y-Ba-Cu-O (YBCO) bulk superconductors is essential for improving …

A successful simple multi-seeding approach to growing large size Y–Ba–C–O (YBCO) bulks
is reported. Compared with the common single seeding method, our multi-seeding method …

The external magnetic flux density and distribution of the permanent magnet (PM) rotor of
the high-temperature superconducting (HTS) magnetic bearing directly affect the load …
