项目摘要

0521644KellerThis Major Research Instrumentation (MRI) Program supports upgrade of 370 RefTek 125 single channel "Texan" seismic recorders located at the University of Texas at El Paso (UTEP). A current pool of 440 Texan instruments have limited on board memory, proprietary CPUs that are no longer supported and cannot be replaced upon failure, and require a proprietary bridge computer for data download. The upgrades (to RefTek 125A standards) will include replacement of the CPU, increased random access memory (RAM) by a factor of eight, and replacement of power supply boards. The upgraded instruments will offer a 400 times improvement in bit transfer rate and will include a USB port for data download from any USB port equipped PC. The instruments will be community accessible through the IRIS-PASSCAL instrument facility for support of active source and passive seismic imaging studies of the crust and upper mantle. The instrument pool will give UTEP students regular access to this state-of-the-art equipment. UTEP is a Hispanic Serving Institution with a student body that is 71% Hispanic and 10% Mexican. The enhance versatility and usability of the Texan seismic recorders will expand opportunities for underrepresented student research and educational experiences with seismic subsurface exploration techniques.***

0521644 Keller这个主要研究仪器（MRI）计划支持位于埃尔帕索德克萨斯大学（UTEP）的370个RefTek 125单通道“德克萨斯”地震记录仪的升级。目前有440台德克萨斯仪器的板载内存有限，专有CPU不再受支持，故障时无法更换，需要专有桥接计算机进行数据下载。升级（到RefTek 125 A标准）将包括更换CPU，将随机存取存储器（RAM）增加到8倍，以及更换电源板。升级后的仪器将提供400倍的比特传输速率提高，并将包括一个USB端口，用于从任何配备USB端口的PC下载数据。这些仪器将通过IRIS-PASSCAL仪器设施向社区提供，以支持地壳和上地幔的主动震源和被动地震成像研究。仪器池将让UTEP学生定期使用这种最先进的设备。 UTEP是一所西班牙裔服务机构，学生人数为71%西班牙裔和10%墨西哥裔。德克萨斯地震记录仪的增强的多功能性和可用性将扩大代表性不足的学生在地震地下勘探技术方面的研究和教育经验的机会。
