An Extended Range Pendulous Velocity Gage,
LAWRENCE LIVERMORE NATIONAL LAB CA
This paper describes the modification of a transducer to extend its dynamic range. These transducers would be used to measure the response of geologic media to stress waves generated during and after underground tests performed by the Lawrence Livermore National Laboratory LLNL at the Department of Energys Nevada Test Site. Included are descriptions of the previously used transducers as well as the modified transducers, their calibration and fielding. The successful extension of range of these transducers will allow the existing measurements system to be more valuable tool for the LLNL data analysts. The system will be used in the continuing effort to understand geologic phenomena of underground testing.
