SUPPORTING FACILITIES

Planetary Electrical Properties and Geochemistry (PEPG) Laboratory

The PEPG ("Pep-gee") Lab characterizes planetary materials for basic research and to enable instrument and mission development for subsurface exploration of the Moon and Mars. Bob Grimm, Mark Bullock, and David Stillman collaborate.

* Solartron 1260 Impedance Analyzer with 1296 Dielectric Interface for highly resistive amples.Measures complex permittivity (dielectric constant and resistivity) <1 mHz - 1 MH

* Anritsu VNA Master MS2026A Vector Network Analyzer. Complex permittivity 2 MHz - 6 GHz

* Nicolet FT Infrared Spectrometer (1-20 microns).

* So-Low Freezer with LN2 boost.Create planetary-analog environments down to ~120 K.

* VWR Vacuum Oven

Geophysical Field Equipment

* MT-24-LF (Electromagnetic Instruments, Inc.). Magnetotelluric (passive/natural-field) sounding <1 mHz - 500 Hz.

*Super Mini-Res (L&R Instruments, Inc.). Resistivity/Induced-Polarization meter, 5 Hz.

* PulseEkko 100 (Sensors and Software, Inc.). Ground penetrating radar at 12.5, 25, 50, 100, and 200 MHz.

Through equipment rentals, we can also perform seismic (refraction, reflection, cross-hole), gravity, magnetic, and active electromagnetic surveys.

After completing a 50-MHz survey, Ron "Hoss" McGinnis (SwRI) breaks out 25-MHz antennas at the Volcanic Tableland near Bishop, CA, against a backdrop of early snow on the White-Inyo Mountains. GPR manufacturer Sensors and Software has eschewed black (my system shown here) for yellow, not orange.
