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

这笔赠款支持购买超导岩石磁强计(SRM)，该仪器配置为对取自沉积物岩心标准段的1.5m u通道进行高空间(平均间隔4.5厘米)磁测量。利用最近开发的脉冲管制冷机的2-G企业SRM系统将消除对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海洋与大气科学学院(COAS)教职员工及其学生的研究。将有助于研究全新世和更深时间的地磁场行为(例如，反转、漂移和古强度)、磁地层学、构造和环境古地磁学。SRM将服务于更广泛的地球科学界，对俄勒冈州海洋地质库的沉积物进行磁性测量，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芯。该仪器将是美国西海岸第一个此类仪器，收集的数据将通过社区数据库(MAGIC)提供。这些私人投资者是俄亥俄州立大学荣誉独立研究计划、哈特菲尔德海洋科学中心REU计划和美洲原住民海洋和空间科学计划的导师。

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.
