MAGNETICS, MATERIALS & ASSEMBLIES CMR Releases Desktop Magnetic Printer for Advanced Magnetics Assemblies Correlated Magnetics Research (CMR) has released the desktop version of its precision magnetizer. The Mini MagPrinter is targeted toward product design and prototyping with customized magnets made possible by CMR's new magnetics technology. The Mini MagPrinter system includes CMR's Polymagnet Catalog of pre-engineered magnetic functions, and the design software to customize magnet strength and behavior. The Mini MagPrinter is a rapid-prototyping magnetization system that "prints" arrays of magnetic regions onto a single piece of magnetic material to produce a Polymagnet. A Polymagnet is a patterned magnet tailored to perform novel magnetic functions that designers can integrate into consumer and industrial products. Each Polymagnet is a system of smaller magnets, both north and south poles, that are imprinted by the MagPrinter. A conventional magnet can be turned into a Polymagnet by placing the magnet into the MagPrinter, choosing a pattern from the Polymagnet Catalog and re-programming the magnet to exhibit a number of different functions. The Mini MagPrinter produces Polymagnets on the strongest Neodymium magnets, flexible materials, ferrites and specialized materials such as samarium cobalt. "CMR's first MagPrinter made programmable magnet systems possible by defining magnets in software for variable strength, reach and function. Defining a magnet in software is a huge improvement over conventional magnets, which are defined simply by their size and grade," said Andy Keane, president and CEO of Correlated Magnetics Research. "Our new desktop MagPrinter will do for magnetics what 3D printing systems did for mechanical prototyping. Designers now have a powerful prototyping tool for programmable magnetics in an affordable desktop system that is perfect for consumer and industrial engineering teams." Polymagnet applications range from advanced functions not possible with conventional magnets to very high strength magnets for traditional attachment. With more sophisticated patterns, Polymagnets behave as magnetic springs, latches or connectors that self-align with very high precision. When used for attachment, a Polymagnet concentrates the strength near the surface of the magnet. This not only increases the attachment strength more than five times that of a conventional magnet, but it also reduces the risk to magnetically sensitive electronics and the accidental attraction of nearby metal or other magnets. All of these behaviors can be customized using CMR's Polymagnet design software. Bruker Installs Compact 900 MHz Actively Refrigerated Magnet for NMR Spectroscopy Bruker Corp. has announced the successful installation of an Ascend Aeon 900 magnet, the first compact, single-story NMR magnet with active refrigeration at the University of California, San Diego (UCSD). The Aeon technology integrates advanced refrigeration technology into the magnet design, thus providing independence from the periodic cryogen refills customary with traditional NMR magnets. The Ascend Aeon 900 is a liquid nitrogen-free, superconducting magnet system with helium reliquefaction technology. It enables 18 Magnetics Business & Technology * Spring 2014 long-term, carefree operation without user maintenance and with essentially helium-consumption-free operation. Whereas traditional 900 MHz magnets require two-story laboratories, the new compact Ascend Aeon 900 magnet can be placed in singlestory labs due to advancements in superconductors, jointing technologies and novel magnet designs. Researchers with restricted laboratory space can now benefit from the sensitivity and dispersion of ultra-high field solid-state NMR with this first ever singlestory 900 MHz magnet. The reduced height and minimum stray magnetic fields of this magnet maximize siting flexibility and reduce site preparation costs. With the introduction of Aeon technology for 400 to 700 MHz NMR magnets earlier this year, and now the Ascend Aeon 900, Bruker continues to respond to concerns regarding potential Helium shortages and increasing Helium costs. Ascend Aeon magnets achieve this by combining the latest active-shielding technology with Bruker's advanced, proprietary refrigeration designs, featuring integrated lowvibration cryo-coolers for reliable long-term operation. The University of California, San Diego purchased the Ascend Aeon 900 magnet together with Bruker's AVANCE III HD NMR spectrometer to provide NMR capabilities at the UCSD Biomedical Technology Research Center (BTRC) for Molecular Imaging of Proteins. The instrument will be used for the development and application of high-resolution solid-state NMR spectroscopy to proteins in biological supramolecular assemblies, especially membranes. The Collaborative and Service activities of the BTRC ensure that the instrument is available to the UCSD biomedical research community. New Miniature, 3.3 V Linear Hall-Effect Sensor IC Allegro MicroSystems, LLC has introduced a linear, Hall-effect sensor IC specifically designed for applications that require medium accuracy in a very small package. Allegro's A1304 is a factory trimmed one-time programmable (OTP-ROM) 3.3 V linear Halleffect sensor integrated circuit that eliminates the need for customers to program the device to compensate for temperature effects on sensor performance. This device has been specifically designed for both consumer and industrial markets, and consequently supports an industrial temperature range of -40°C to 85°C. Allegro's A1304 has a typical programmable sensitivity level of 4 mV/G ±6 percent. Sensitivity and QVO TC are blind blown (trimmed) at the factory for improved accuracy relative to other low cost linear IC's from Allegro (A1301/02). A1304 device complements Al-
