NanoSIMS 50

Our NanoSIMS 50, the first one produced by CAMECA, was designed specifically for the presolar grain research that we do. This new type of ion microprobe offers a lateral resolution of better than 100 nanometers, high sensitivity and multi-collection capability. In May 2018, we installed a Hyperion 201 RF plasma ion source that will allow us to measure secondary positive ions with a beam size of 50-100 nm. Visit the NanoSIMS homepage for more information.


 

Field-Emission Scanning Electron Microscope

Our Tescan Mira3 FEG-SEM is a state-of-the-art scanning electron microscope that features a high-brightness Schottky emitter, wide-field optics for a large field-of-view, EDAX EDX system for X-ray analysis, integrated STEM detector, ImageSnapper software that automatically collects multiple SE or BSE images while adjusting focus, contrast, and brightness. Its open software platform allows for complete and customized control of the microscope through Python scripting.

Auger Nanoprobe

Our PHI 700 Auger Nanoprobe operates with a field emission electron source and can be operated as a field emission scanning electron microscope (FE-SEM). In addition, qualitative and quantitative analyses (for all elements except H and He) can be carried out with a spatial resolution on the order of tens of nanometers, making it an ideal complement to the NanoSIMS.

Focused Ion Beam Instrument

Our focused ion beam (FIB) instrument extends the reach of our studies into the submicron realm. Our instrument is a FEI 3D FEG Dual Beam (electron beam and gallium ion beam) FIB with an in situ Omniprobe manipulator. The FIB allows us to image and manipulate submicron presolar grains as well as to cut and extract sections sufficiently thin for transmission electron microscopy (TEM).

FEI Titan3 G2 60-300 dual aberration-corrected TEM/STEM

The University of Hawai‘i’s Titan monochromated and dual aberration-corrected (scanning) transmission electron microscope.

A dual reservoir liquid nitrogen environment chamber built by Infrared Laboratories. It features two windows, one for illuminating the sample with a solar simulated source, and one for viewing the sample with the Designs and Prototypes Spectrometer (2.5 to 14 microns). Samples are illuminated with an arc lamp to produce solar-like illumination. Environment control ranges from room temperature down to 80K (-315° F or -200° C).

California State University, San Marcos

The laboratory at CSUSM is a state-of-the-art facility for studying isotope exchange and infrared spectroscopy of materials with 10-20 nanometer lateral resolutions. Dr. Dominguez uses multiple instruments in his research.

  • A Bruker AFM-IR with Scanning Near-field Optical Microscopy (SNOM)
  • A customized Picarro L2120-i cavity ringdown isotope ratio mass-spectrometer for the simultaneous determination of D/H, and D18O and D17O ratios in water samples (liquid or vapor)
  • A Thermo-Nicolet FTIR and Nexus 470 IR microscope (for bulk IR characterization of materials and standards)

And backed by advanced equipment:

  • A 12” diameter custom built UHV chamber with an assortment of CF ports (2.75”,6”) to accommodate UHV qualified instrumentation
  • Two ColdEdge helium closed cycle cryostats (UHV CH-204 Cold Head, 5-350 K)
  • Two Kimball Physics electron gun (2-2000 eV, 1mA max and (2-5keV, 0.1 mA max)

University of Winnipeg

The University of Winnipeg’s Centre for Terrestrial And Planetary Exploration (C-TAPE) conducts research to support the exploration of planetary solid surfaces. It is equipped with an array of field-portable instrumentation (e.g., Raman and reflectance spectrometers, X-ray diffractometers and X-ray fluorescence spectrometers), as well as an array of environment chambers that can reproduce a range of planetary conditions and that can be interfaced to various spectrometers. C-TAPE also hosts an extensive spectral database.
