The high voltage (HV) insulation on the ITER magnet feeder superconducting busbars and current leads will be prepared from R-glass fabric, pre-impregnated with an epoxy resin, which is interleaved with polyimide film and wrapped onto the components and cured during feeder manufacture. The insulation architecture consists of 7 half-lapped layers of glass/Kapton, which is then enveloped in a...
Recent studies on prototype undulator magnets showed that second-generation high temperature superconducting (2G-HTS) tapes are suitable for use in undulators to enhance their performances substantially. However, providing sufficient mechanical stability and rigidity to the magnet windings have remained a challenge. Vacuum epoxy impregnation is a widely employed technique to improve the...
Composite materials, due to their high strength to weight ratio, are deployed in various aerospace applications such as skins of the empennages (aircraft), launch vehicle bodies, support structures in spacecraft, etc. However, the cryogenic tanks for storing super cooled fuels such as liquid nitrogen (LN2), liquid oxygen (LOX), liquid hydrogen (LH2), etc. in spacecraft are still constructed by...
The special test facility consisted of 15.5 T superconducting magnet and a variable temperature insert (VTI) has been installed in the radiation control area at Oarai center in Tohoku University in Japan. The VTI has a high purity aluminum rod with over 6 nine to remove the heat from a sample holder to GM refrigeration. Also, it has a pair of pure copper bus bars of 500 A. Since these...
One major inhibitor to a hydrogen society is economical systems to support safe storage and transportation of this fuel. Magnetic refrigeration has emerged as a promising technology for hydrogen liquefaction due to its potential high efficiency and environmentally friendly operation. Magnetic refrigeration utilizes the magnetocaloric effect (MCE), which is the temperature variation of a...
Wire drawing is a tremendously expanding industry which incorporates manufacturing of steel wires having applications in automotive, construction, agriculture, and equipment manufacturing industries. The wire drawing die is usually manufactured from tungsten carbide and cobalt binder, commercially called as cemented carbide.The tungsten carbide die plays a vital role in shaping wires. In this...
