Cryogen Reclamation for NMR Superconducting Magnets Launched by JEOL 

November 13, 2023 Editorial Staff Comments Off on Cryogen Reclamation for NMR Superconducting Magnets Launched by JEOL 

Liquid helium and nitrogen can be expensive ingredients for cooling the superconducting magnet in many nuclear magnetic resonance systems. The volatile elements are prone to evaporating away and requiring replenishment to maintain optimal performance of the instrument. Sometimes the instruments have to be shut down while fresh cryogen supplies are sought. But reclaiming them can make a difference.  […]

Luvata Pursues EV Market to Apply Hollow Magnet Wire in Direct Cooled Stators 

September 27, 2022 Editorial Staff Comments Off on Luvata Pursues EV Market to Apply Hollow Magnet Wire in Direct Cooled Stators 

Direct-cooled motors with hollow conductor stators offer several advantages over the indirect-cooled motors currently used in EVs, says Luvata of Finland, which has been making copper hollow conductors for more than sixty years. Adoption of the technology, typically used in more exotic applications such as superconduction, high-energy physics and magnetic resonance imaging, into mass-market electric vehicles faces considerable technical obstacles, however, and much higher cost than conventional magnet wire.  […]
