One large (9ft long by 5ft diameter) and one small (2 ft long by 1 ft diameter) plasma chambers are used to study advanced plasma systems that would facilitate low cost in-space propulsion to further space exploration. Concepts presently being investigated include small scale micro-thrusters for small multi-spacecraft missions to very large high power systems for potential large spacecraft. Students participate in the development and optimization of prototypes using an array of plasma diagnostics and a fast data acquisition systems. For more information, contact Robert Winglee.
The Aeronomy and Optics Lab serves as an educational, training, research and development facility, as well as being the staging area for our field site experiments in Antarctica and New Zealand, where Global Climate Change studies in the Southern Hemisphere are in progress. The laboratory serves as the support arm for these far away experiments, as well as to provide new and improved optical instrumentation which will perform measurements with higher precision than previously attained, rugged instrumentation for unmanned sites, or to study atmospheric species which have not been used previously as tracers in our remote-sensing studies. In addition, design and fabrication of instrumentation which supports the main optical studies, such as an unmanned sunlight-insensitive cloud detector, have been carried out in the Aeronomy and Optics laboratory. As part of the support, the laboratory is where the Antarctic Research Associates receive their yearly training. The laboratory investigations provide a wide range of research possibilities for students. For more information, contact Gonzalo Hernandez or Michael McCarthy.
The Atmospheric Electrodynamics Lab in the Space Sciences Group is a space for electronics development and deployment, as well as for payload fabrication for suborbital flights. We have both fabrication benches, as well as operational network computers for the WWLLN lightning network in the Atmospheric Electrodynamics Lab. Additionally, we share a large Assembly Room with the other Space Science Labs for balloon and rocket payload buildup. Our lab has a conduit to the roof for VLF and GPS antenna deployment. We share a clean room for dust free flight instrument development. The Atmospheric Electrodynamics Lab is the home of the WWLLN: World Wide Lightning Location Network. We build the hardware, and process the incoming global data in this lab. Additionally, we have built electric field and optical transient detectors for dozens of stratopheric balloon and for several upper atmospheric rocket flights. These flight instruments led to the optical lightning detector now flying on the C/NOFS satellite. For more information, contact Robert Holzworth.

For more information, contact John Stone, Director.
Electron Microprobe Laboratory
The microprobe is a JEOL 733 Superprobe. This instrument combines four wavelength dispersive spectrometers (WDS) and one energy dispersive spectrometer (EDS) with scanning electron microscope (SEM) capabilities to create an extremely powerful, yet easily accessible, micro-analytical instrument. The WDS system has diffracting crystals capable of producing quantitative analyses of the elements boron (Z=5) through uranium (Z=92). We also have an extensive and well characterized collection of mineral and glass standards. We use the GELLER dQant-dPict automation and imaging system. The imaging system can be used to acquire and digitize backscattered (BSE) and secondary electron (SE) images and elemental x-ray maps. The dPict imaging system is integrated with the microprobe stage motors and can very easily produce large area (very low magnification) mosaic images of entire thin sections (BSE, SE or x-ray). For more information, contact Scott Kuehner, Electron Microprobe Laboratory! Manager (kuehner @ u.washington.edu)

GIS (Geographical Information Systems) Research Laboratory
The GIS Research Lab (known as the Puppet Lab for arcane historical reasons) specializes in the analysis of topographic data and geographical information systems applications. The lab is located next to the Quaternary Research Center (QRC) and houses a Spatial Data Engine, Internet Map Server, mammoth file server and web servers, and powerful student workstations with GIS and image processing software. Although the lab is open for use across the department, research projects in the lab tend to focus on geomorphological topics involving the analysis of digital topography on Earth and Mars. For more information, contact Harvey Greenberg, Senior Computer Specialist.
The IsoLab specializes in the analysis of light stable isotopes. The IsoLab is divided into sample preparation and sample analysis laboratories and has five mass spectrometers and one laser devoted to the analyses of carbon, nitrogen, hydrogen, oxygen, and sulfur. Research projects in the IsoLab are primarily focused on the application of stable isotopes to the study of paleoenvironments and the evolution of the earth system. For more information, contact Andrew Schauer, IsoLab Manager.
The Laser Ablation ICPMS Lab specializes in the analysis of trace elements concentrations and isotopic ratios of solid material at high spatial resolutions (10-100 microns spot sizes). Samples, in the form of rock thin sections, polished slabs or grain mounts, are placed in an ablation chamber equipped with a high-resolution camera. After choosing an area of interest, the sample is ablated by a short wavelength (193 nm) laser pulse and carried by a He flow to the ICPMS (Nu instrument multi collector or Finnigan SOLA quadropole ICPMS). Research projects focus on the trace elements characterization and radiogenic isotopic ratios of magmatic minerals to study volcanic processes and evolution of the Earth's mantle and crust. For more information, contact Bruce Nelson.
The Rockets and Instrumentation Lab designs and builds rockets to launch science payloads to high altitude using high power amateur rockets. Design, fabrication, testing, and integration all happen in house, with the rockets which are then launched at an offsite (Mansfield WA, Black Rock NV, and China Lake CA). Past projects include high altitude launch systems (via kite and weather balloon), cluster and multistage rockets, and a penetrating system for sample return.
The Remote-Sensing Lab supports the research efforts of the terrestrial and planetary remote-sensing efforts within the Department of Earth and Space Sciences. It has provisions for an optical bench, a fume hood, and room for a 2-m environmental chamber for spectral characterizations.
