New Capabilities
EMSL is starting a multi-year process to upgrade and replace some instruments. Some of these capabilities are already online while other instruments are at differing stages of the procurement and installation processes.
New Capabilities currently in place include:
- X-ray Diffraction: microbeam – microbeam diffractometer with Cu and Cr anodes and spatial resolution as high as 10-µm
- Electron Microscope: Dual-Beam FIB/SEM – performs FIB/SEM, EBSD, EDXS, and STEM and has a focused spot size of 7nm or smaller
- Electron Spectrometer: Scanning Multiprobe Surface Analysis System Versaprobe – new generation time-of-flight secondary ion mass spectrometer, including C60 ion beam
- Microscope Photoemission Electron (PEEM) – two-photon PEEM upgrade allows users to obtain PEEM images with greater than 30-nm spatial resolution and greater than 30-femtosecond time resolution for surface dynamics measurements
- Mass Spectrometer: Aerosol time-of-flight, high resolution high-resolution mass spectrometer for in situ chemical analysis of catalyst surfaces and particle imaging using novel atmospheric pressure surface ionization techniques
- Time of Flight Secondary Ion (ToF SIMS)
The following capabilities are planned to be in operation in the near term. At this time, these capabilities cannot be selected on user proposals. Researchers interested in requesting these capabilities should contact the Capability Steward listed.
- 600 MHz LC-NMR instrument to support biological interactions and dynamics and, in particular, metabolomics science. The system has an HCN triple resonance cryoprobe optimized for 1H observation, has better salt tolerance and increased 13C sensitivity from previous cold probe technology, and can be run in automated tube or flow modes. A broadband probe will also be available for limited study with 31ρ-15N direct observation. System allows automated tuning and gradient shimming (available Summer 2008).
Contact: David Hoyt - Microfluidics capabilities for studying reactive chemical transport in micron or smaller confined spaces are being developed to better understand geochemical and biogeochemical reactivity as well as to help bridge the gap between molecular and continuum scales (available Fall 2008).
Contact: Nancy Hess - Second harmonic generation and sum frequency generation capabilities for probing interfacial reactions in situ are being developed (available Fall 2008).
Contact: Nancy Hess - EMSL's new Hewlett Packard supercomputer, named Chinook, will offer users 2,310 compute nodes, 162.624 trillion calculations per second peak performance, and 36.96 TB of memory
