9404891 Van Schmus This award provides one-half the funding necessary to upgrade the counting system of a mass spectrometer purchased in 1986. The thermal ionization mass spectrometer will acquire new Faraday cups and a new ion counting system. The upgraded equipment will continue to be operated for research and teaching purposes in geochemistry in the Department of Geology at the University of Kansas. The University is committed to providing the remaining funds needed to pay for the upgrade. Research applications include measurements of uranium- lead, samarium-neodymium, and rubidium-strontium isotopic systematics for dating and determining the origin of igneous rocks associated with regional tectonic processes and crustal evolution. ***

小行星9404891 该合同提供了1986年购买的质谱仪计数系统升级所需资金的一半。热电离质谱仪将获得新的法拉第杯和新的离子计数系统。升级后的设备将继续用于堪萨斯大学地质系的地球化学研究和教学。大学承诺提供升级所需的剩余资金。 研究应用包括测量铀-铅、钐-钕和铷-锶同位素系统学，以确定与区域构造过程和地壳演化有关的火成岩的年代和起源。 ***
