Technician Support: EPS TIMS Facility at Harvard (Phase II)

0093645 Jacobsen该基金支持哈佛大学地球与行星科学系（EAPS）购置一台五倍频（193 nm波长）深紫外（DUV）激光器，该激光器将与电感耦合等离子体质谱仪（四极杆和多集电极）连接。 激光烧蚀系统将允许继续进行研究，需要对地质和地球外物质进行原位和空间分辨同位素分析。 该激光系统将支持哈佛的几位教职员工的研究，包括Stein Jacobsen（壳幔地球化学和宇宙化学），Dan Schrag（海洋化学和古海洋学），Paul霍夫曼（新元古代构造和气候）和Heinrich Holland（地球早期大气的演变）以及他们的研究生和博士后。 ***

0093645JacobsenThis grant supports the acquisition of a frequency quintupled (193 nm wavelength) deep ultraviolet (DUV) laser to be interfaced with inductively coupled plasma mass spectrometers (both a quadrupole and a multicollector) in the Department of Earth and Planetary Sciences (EAPS) at Harvard University. The laser ablation system will allow continued studies requiring in situ and spatially resolved isotopic analysis of geological and extraterrestrial materials. The laser system will support research by several faculty members at Harvard including Stein Jacobsen (crust-mantle geochemistry and cosmochemistry), Dan Schrag (marine chemistry and paleoceanography), Paul Hoffman (Neoproterozoic tectonics and climate) and Heinrich Holland (evolution of Earth's early atmosphere) as well as their graduate students and postdocs. ***
