Collaborative Proposal: Development of a replacement for the STS-1; Mechanical Sensor Development and Test

0744045 VanZandt该奖项由NSF和USGS共同资助，将允许加州大学伯克利分校（BSL）的伯克利地震实验室与其商业合作伙伴Metrozet有限责任公司（加利福尼亚州托兰斯）合作，开发和测试用于Streckeisen STS-1甚宽带（VBB）地震仪的新机械传感器。STS-1被广泛认为是世界上最好的VBB传感器，目前是全球地震台网（GSN）和其他几个全球或区域地震台网使用的主要地震计。它的继续运行对地震学中一些重要学科的未来基础研究至关重要。这包括对地球内部深处的研究，对特大地震震源过程的确定，以及海啸预警。 然而，STS-1已不再进行商业生产。 该团队的最终目标是开发一种设计，使集成的三轴STS-1传感器能够以与当前（较低性能）传感器具有竞争力的成本进行制造，销售和支持。 同样重要的是，新传感器的交货期比许多过去和现在的传感器更短。 这项工作还将为加州大学伯克利分校的地震仪器工程师、博士后研究人员和研究生提供重要的教育和培训机会。

0744045VanZandtThis award, jointly funded by NSF and the USGS, will permit the Berkeley Seismological Laboratory of the University of California at Berkeley (BSL), in collaboration with its commercial partner, Metrozet, LLC (Torrance, CA), to develop and test new mechanical sensors for the Streckeisen STS-1 Very Broad-Band (VBB) seismometer. The STS-1, widely viewed as the finest VBB sensor in the world, is currently the principal seismometer used by the Global Seismographic Network (GSN) and several other global or regional seismic networks. Its continued operation is critical to future, fundamental research in a number of important disciplines within seismology. These include studies of the earth's deep interior, the determination of source processes of very large earthquakes, and tsunami warning. However, the STS-1 is no longer manufactured commercially. The ultimate goal of the team is to develop a design that allows an integrated, triaxial STS-1 sensor to be manufactured, sold, and supported at a cost that is competitive with current (lower performance) sensors. Of equal importance is that the new sensor be available with shorter leadtimes than is typical with many past and current sensors. This work will also provide significant educational and training opportunities for seismic instrumentation engineers, postdoctoral researchers, and graduate students at UC Berkeley.
