Zenno Superconducting Magnetic Torquers Aim to Refine Satellite Positioning 

March 6, 2025 Editorial Staff 0

Superconducting magnetic torquers for high-precision satellite positioning from Zenno Astronautics in Auckland, New Zealand are bringing a new application for high-temperature superconductor tape into the spotlight. The novel devices are attracting innovation funding from Asia-Pacific sources and are set to use HTS tape from Faraday Factory Japan that can conduct electrical currents with zero electrical resistance and an extremely high current density of several hundred amperes per square millimeter.

The company’s Z01 torquer scales to address satellites from 50kg up to space station sized, powering their frequent needs to make spatial adjustments while in orbit. The torquer presents a fuel-free “non-propellant” solution that in 2023 became the first such device to go into space. […]

Magnetron Leader CPI Electron Devices Now Part of TransDigm 

February 27, 2025 Editorial Staff Comments Off on Magnetron Leader CPI Electron Devices Now Part of TransDigm 

CPI Electron Device Businesss is the new name for one of the world’s largest producers of magnetrons and a prolific developer of electromagnetic systems for aerospace and defense markets, as a result of its acquisition by TransDigm from Communications & Power Industries. Before it was spun out from CPI in mid-2024 and acquired by TransDigm for about $1.385 billion, it was formerly the Electron Device Business of Varian Associates and has long been a global manufacturer of electronic components and subsystems including radio frequency and microwave products. Now CPI-EDB operates as one of the more than 50 companies owned by Transdigm which primarily provide aircraft components for commercial and military fleets around the world.  […]

Magnetic Imaging with SQUID sensitivity by Quantum Design, and New CEO 

February 19, 2025 Editorial Staff Comments Off on Magnetic Imaging with SQUID sensitivity by Quantum Design, and New CEO 

The QDM.IO is the first system on the market which provides large area imaging of the magnetic field distribution using measurement based on nitrogen-vacancy centers implanted in a diamond. Conventional NV center-based microscopes use a single NV center in the tip and scan the sample, however, the heart of this microscope is a chip with many NV centers which can measure a large area simultaneously. The result is nanotesla sensitivity that not only detects the strength but also the local vector of the magnetic field.  […]
