Custom Design In Situ TEM Holder for the Development of a Multimodal Ultrafast Electron Microscope to Investigate Chemistry and Physics in Energetic Materials
Abstract
Funds are requested for the purchase of a custom design in situ TEM holder to significantly enhance the ultrafast in-situ characterization capabilities in our lab to investigate the dynamical processes of energetic materials at extreme conditions. Currently, an ultrafast transmission electron microscope (UTEM), picoseconds time resolution streak camera with a spectrograph and ultrafast lasers are all available in our lab to perform simultaneous time-resolved electron imaging and optical spectroscopy for multimodal investigation of the energetic materials. The requested funds will be utilized to acquire a holder, which is specifically designed to collect light from small TEM samples. The requested equipment will enable very high light collection efficiency for high time-resolved, 1 picosecond, experiments drastically improving our diagnostic capabilities. One facet of this proposal, and related current work, is the development of a truly unique capability in the world, multimodal ultrafast TEM. The motivation for the proposed set of instrument enhancements is to considerably extend the laboratory capabilities to dynamically characterize energetic materials and is also applicable to many other materials and for various applications. A number of ongoing research projects in the PIs laboratory are directly related to DoD research and development interests and will greatly benefit from the proposed characterization system. This system is also widely applicable to numerous other current DoD projects, both inside and outside University of Connecticut. We anticipate collaborations with numerous other universities and labs because of the unique capabilities that will be developed. In summary, the requested instrumentation complements our current capabilities and would dramatically impact numerous programs and will also greatly benefit the education of our students.
