Introduction
Andrew John Varney is a notable inventor based in Oxford, GB. He has made significant contributions to the field of superconducting magnet systems, holding two patents that showcase his innovative approach to cryogenic technology.
Latest Patents
Varney's latest patents include a groundbreaking system for the cryogenic cooling of superconducting magnet systems below a temperature of 4.2 K. This system features a cryogenic vessel that houses a superconducting magnet, which is cooled by liquid helium. The design allows for the supply of current to the magnet through a removable current lead, enabling the magnet to maintain superconducting current flow even after the lead is removed. This innovative approach allows the system to operate at very low temperatures, producing high-strength and stable magnetic fields suitable for NMR spectroscopy.
Another significant patent is for a superconducting electromagnet apparatus. This apparatus includes a main coil assembly and a main current supply that energizes and de-energizes the coil. It is designed to maintain a constant current flow, generating a highly homogeneous central magnetic field. The apparatus also features a B shim coil assembly that provides fine adjustments to the magnetic field without degrading its homogeneity. This dual functionality simplifies the design and enhances the performance of the electromagnet.
