Lab facilities

Along with the geophysical instrumentation at CGISS, the ESLab has 7 quick deploy Nanometrics Meridian Compact PH broadband seismometers. We use these sensors for anything from volcano monitoring to white water rapid studies and everything in between.

Prepping for installation at the top of Llaima Volcano, Chile. The Meridian Compact PH is in the blue box. Everything but the battery and solar panel fit in the box!

The ESLab also maintains a laser ultrasonics laboratory. Below is a list of the larger ticket items within that lab that we use to study wave propagation at the ultrasonic scale.

  • Polytec Scanning Vibrometer (PSV-500)
  • Bossa Nova TEMPO normal incidence interferometer
  • Bossa Nova TEMPO 2D interferometer
  • Spectra Phyiscs Pulsed Nd:YAG laser
  • AlazarTech ATS660 PCI oscilloscope card
  • Computer-controlled X-Y translational stage system
  • Computer-controlled rotational stage
  • Optical bench (with vibration isolation and overhead shelving system)
  • Cold room with optical (sapphire) windows (-20 C +/- 0.1 C)
  • Function generators (SRS)
  • Low-noise preamps (SRS)
  • A lock-in amplifier (SRS)
  • Ultrasonic P- and S-wave video-scan transducers
  • Data acquisition PC
