HTS Tape Manufacturers Scale Up for Magnetic Tokamak Growth for Fusion Energy 

November 16, 2023 Editorial Staff Comments Off on HTS Tape Manufacturers Scale Up for Magnetic Tokamak Growth for Fusion Energy 

The prospect of carbon-free energy from fusion has accelerated the development of tokamaks in recent years, driving the demand for high-temperature superconductor (HTS) tape, the technology at the heart of the extremely strong electromagnets used to confine plasma in magnetic-confinement fusion reactors. Now, manufacturers of HTS tape, notably Faraday Factory and Fujikara, both located in Japan, are ramping up their production capabilities and deliveries as the global demand for HTS tape is expected to grow tenfold in the next five years. Lasers from Coherent Corp. are playing a key role.  […]

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.  […]

Magnetism May Have Given Life Its Molecular Asymmetry 

September 26, 2023 Editorial Staff Comments Off on Magnetism May Have Given Life Its Molecular Asymmetry 

Living things are asymmetrical, even at the molecular level: Although many essential biomolecules exist in distinct mirror-image forms, cells tend to use just one of those forms exclusively. An article in Quanta Magazine sheds light on the concept of chirality and research into its origins involving primordial magnetism. A few excerpts of the fascinating article here: […]

Hall-Effect Thrusters from Busek to Propel Artemis Gateway 

September 19, 2023 Editorial Staff Comments Off on Hall-Effect Thrusters from Busek to Propel Artemis Gateway 

As space missions probe deeper and last longer, electrified propulsion systems powered by Hall-effect thrusters are proving their mettle. One company leading the way is Busek, a pioneer in Hall-Effect technology for aerospace whose thrusters will be aboard NASA Artemis missions seeking the return of humans to the moon. […]
