Development of a Closed Cycle Cryostat for Full-Vector, Low-Temperature Magnetic Measurements of Geologic Materials

0929807 Feinberg该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助。 获得的资金将支持开发一种低温恒温器，该恒温器能够在磁性矿物中进行全矢量剩磁测量，直至低温（范围为25至350 K）。 低温恒温器的设计将匹配标准的2-G企业射频和直流SQUID岩石磁力计。 所开发的低温恒温器的研究应用可能导致用于确定岩石、沉积物、陨石和合成磁性介质中铁磁矿物的相特异性低温磁性行为的新技术，过去环境条件的新岩石磁性代理的开发，以及工业应用可能导致改进的磁性介质设备的开发。 拟议的低温恒温器设计涉及明尼苏达大学和美国低温设备制造商（ColdEdge Technologies）之间的合作。 该基金资助了两名早期职业科学家。

0929807Feinberg This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). Granted funds will support development of a cryostat capable of full vector magnetic remanence measurements in magnetic minerals to low temperatures (range 25 to 350 K). The cryostat design would mate to standard 2-G Enterprises RF and DC SQUID rock magnetometers. Research application of the developed cryostat is likely to result in new techniques for determination of phase specific low temperature magnetic behavior of ferromagnetic minerals in rocks, sediments, meteorites and synthetic magnetic media, the development of new rock magnetic proxies of past environmental conditions, and industrial applications may result in the development of improved magnetic media devices. The proposed cryostat design involves a collaboration between the University of Minnesota and a U.S. cryogenic device manufacturer (ColdEdge Technologies). The grant supports two early career scientists.
