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

该合同由美国国家科学基金会和美国地质勘探局共同资助，将允许加州大学伯克利分校伯克利地震实验室（BSL）与其商业合作伙伴Metrozet， LLC （Torrance， CA）合作开发和测试用于Streckeisen STS-1 Very Broad-Band （VBB）地震仪的新型机械传感器。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仪。它的持续运作对未来地震学中许多重要学科的基础研究至关重要。其中包括对地球深层内部的研究，确定特大地震的震源过程，以及海啸预警。然而，STS-1已不再商业化生产。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（低性能）传感器具有竞争力的成本制造，销售和支持。同样重要的是，与许多过去和当前的传感器相比，新传感器的交货时间更短。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。

0744021RomanowiczThis 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.
