The University of Arizona Electron Microprobe Laboratory is equipped with CAMECA SX100 Ultra and CAMECA SX50 electron probe microanalyzers (EPMA) that perform rapid, non-destructive chemical analysis of solid samples.
As part of university core facilities, LPL houses an FEI Helios NanoLab 660 focused-ion-beam scanning-electron microscope (FIB-SEM). The Helios is equipped with an Elstar electron gun and monochromator and is capable of electron beam resolution down to 0.6 nm from 15 kV to 2kV. Its Tomahawk Ga+ ion column can be operated between 65 nA and 500 V for, respectively, removal of large volumes of material and final sample polishing. Under standard operating conditions, an ion beam resolution 2.5 nm at 30 kV is achievable. The Helios is equipped with in situ micromanipulation for creation and transfer of lamellae for TEM analysis. It is also equipped with an EDAX Energy Dispersive Spectroscopy (EDS) and Electron Backscatter Diffraction (EBSD) analysis system for compositional and crystallographic analysis in two and three dimensions. Multiple polygons are supported for device patterning as well as the ability to directly import customized shapes via BMP files for patterning or deposition. The Helios is equipped with C and Pt gas-injection systems.
The Arizona Noble Gases Laboratory (ANGL) has been in operation at the University of Arizona since 1990. Now under the direction of Dr. Timothy Swindle, it has been very productive in the age dating of meteorites and lunar samples.
Optical instrument fabrication and calibration lab
The LPL optical instrument development and calibration facility supports development and testing of spectroscopic and imaging instruments for use on ground and space based platforms. The laboratory maintains 3 monochromator-fed vacuum calibration chambers with detector systems covering wavelengths from 30-1000 nm. The chambers are installed in a main lab area, a 600 sqft clean room configurable to class 100, and a 300 sqft class 10000 staging room. Optical fabrication is supported by a dark room, electronics lab, and extensive inventories of emission line sources, optical components/stages, and computing resources (Zemax ray tracing software, CAD, and LabView). The facility is managed by Dr. Walt Harris and Dr. Jason Corliss.
The resources at PIRL consist of hardware, software, and people dedicated to providing support for projects in the planetary sciences. Access to PIRL’s electronic resources is via remote connection by SSH or the Web, or at PIRL's public user room, located at the Sonett Space Sciences building in Tucson, Arizona.
The Planetary Materials Research Group maintains a laboratory suite with capabilities in wet chemistry (perchloric acid-rated hood for dissolution of meteoritic materials), ultramicrotome sample preparation of thin electron-transparent samples, optical microscopy (petrographic and stereo microscopes with digital image acquisition), a workstation for graphics processing of three-dimensional data sets, and an 11 m2 class-100 cleanroom for handling/preparation of sensitive materials. The laboratory serves as a staging area for archiving, preparation, and documentation of samples for analysis via electron and ion microscopies described below.
