Abstract:

Future generations of gravitational wave measurements will be polluted with Newtonian noise. For
studying this noise, the ultimate goal of being discovering how to subtract it, seismometers are used at the
former Homestake mine in Lead, South Dakota. A problem with seismometers is that these are designed
for high sensitivity at low frequencies of which wave measurements are not concerned. To obtain a
seismometer that has better sensitivity at higher frequencies (1-30 Hz) the SS-1 Ranger has been looked
at and its parts designed on AutoCAD for sensitivity at 1-30 Hz and modifications made for less
mechanical and electrical noise.
