Acquisition of an Ultrasensitive Superconducting (SQuID) Rock Magnetometer System

小行星9628007 这笔赠款提供65,287美元，作为加州理工学院地质系购买新的2G企业直流（DC）超导磁力计（SQuID）费用的一半。 该仪器将取代具有高故障可能性的过时射频（Rf）SQuID。 新仪器将提供比Rf-SQuID更高的灵敏度和更宽的动态范围，并由于DC-SQuID更有效地使用液氦而显著降低实验室运营成本。 这次收购将使PI继续他在地磁学和生物磁学方面的极受尊敬的研究，并将为该实验室的频繁用户提供宝贵的资源。 ***

9628007 Kirschvink This grant provides $65,287 as one-half support of the cost of acquiring a new 2G Enterprises Direct-Current (DC) superconducting magnetometer (SQuID) for the Department of Geology at the California Institute of Technology. The instrument will replace an antiquated radio-frequency (Rf) SQuID that has a high potential for failure. The new instrument will provide much greater sensitivity and broader dynamic range than the Rf-SQuID and result in a significant reduction in lab operating costs due to the DC-SQuID's much more efficient use of liquid helium. This acquisition will allow the PI to continue his extremely well-respected research in geomagnetism and biomagnetism and will provide a valuable resource to the frequent users of this laboratory. ***
