Aurora mine Slow Ground Motions Studies



      The  goals  of  this  work are  to  develop  a  high-resolution
    system for slow ground motion studies, to perform measurements in 
    the 300  foot depth dolomite Aurora mine to analyze experimental 
    results  and  to  develop  conclusions  and  proposals   for  the
    Next Linear Collider Project.
      The  SGMM   System  is  the universal and power system based on 
    PC-AT to collect simultaneously  the data of up to 20 hydrostatic
    level sensors of different types,of 2 air pressure sensors and of
    up to 8 SM-3KV seismometers.  System  presents   measured data on 
    computer display and stores results on hard disk.
