Acquisition of a 2G Enterprises Superconducting Rock Magnetometer Optimized for U-Channel Samples at Oregon State University

该基金支持购买超导岩石磁力计（SRM），该磁力计配置用于对取自沉积物岩心标准剖面的1.5 m u形通道进行高空间（平均间隔为4.5 cm）分辨率的磁测量。利用最近开发的脉冲管制冷机的2g企业SRM系统将消除液氦冷却到超导温度的需要。该仪器将支持美国国家科学基金会资助的俄勒冈州立大学（OSU）海洋与大气科学学院（COAS）的教师及其学生的研究。将促进全新世及更深层地磁场行为（如倒转、偏移和古强度）、磁地层学、构造学和环境古磁学的研究。SRM将为更广泛的地球科学团体提供服务，对俄勒冈州海洋地质储存库中的沉积物进行磁测量，并研究从综合海洋钻探计划和国际大陆钻探计划中回收的岩心。该仪器将是美国西海岸首台此类仪器，收集的数据将通过社区数据库（MagIC）提供。他们担任俄勒冈州立大学荣誉独立研究项目、哈特菲尔德海洋科学中心REU项目和美国原住民海洋与空间科学项目的导师。

This grant supports acquisition of of a superconducting rock magnetometer (SRM) configured to make high spatial (averaged at 4.5 cm intervals) resolution magnetic measurement on 1.5 m u-channels taken from standard sections of sediment cores. A 2-G enterprises SRM system that utilizes a recently developed pulsed tube cryocooler will eliminate the need for liquid Helium to cool to superconducting temperatures. The instrument will support NSF funded research by faculty and their students in the College of Oceanic and Atmospheric Sciences (COAS) at Oregon State University (OSU). Research on Holocene and deeper time geomagnetic field behavior (e.g., reversals, excursions and paleointensity), magnetostratigraphy, tectonics and environmental paleomagnetism will be facilitated. The SRM will serve the broader geoscience community for magnetic measurements of sediments held at the Oregon State Marine Geology Repository and for study of cores recovered from the Integrated Ocean Drilling Program and the International Continental Drilling Program. The instrument will be the first of its kinds on the U.S. west coast and data collected will be made available through community databases (MagIC). The PIs serve as mentors for the OSU Honors independent study program, the Hatfield Marine Science Center REU program and the Native Americans in Marine and Space Science Program.
