Oxford Instruments Superconductivity has announced that it has successfully completed the production and testing of the world's largest high-performance Nuclear Magnetic Resonance (NMR) magnet.
"Using Oxford Instruments patented technology, combined with high-performance superconducting material from our sister company, Oxford Superconducting Technology, the wide bore (65mm) 900 MHz superconducting magnet performs extremely well, and is exceeding initial specifications,'' explains the company's project manager, Mr Martin Townsend.
''This achievement builds on previous technology that we have developed within our Discovery 900MHz narrow bore (54mm) product range and will form the basis for further high field magnet designs of one GHz and beyond."
The latest development produces a high homogeneity magnet, which runs in persistent mode and utilises Oxford Instruments' unique technology with excellent drift characteristics. The magnet also safely manages 27 megajoules of stored energy, which is monitored using Oxford Instruments' unique Energy Management System (EMS)(tm). This also enhances reliability and the long-term stability of the magnet system.
"This is very important to our customers who intend to use the magnet to study the three-dimensional structures of molecules," points out Mr Townsend. "They require the high performance to obtain continuous reliable information on the molecular structure.''
