The EM Tomography Core is housed within the Jensen lab at the California Institute of Technology in Pasadena, California.  Two electron cryomicroscopes are present there: a 300kV, FEG, liquid helium-cooled, energy filtered, dual-axis tilting, fully automated "G2 Polara" and a 120 kV, LaB6, liquid nitrogen-cooled "Tecnai T12."  The tomography core is involved in structure determinations as well as improving instrumentation, specimen preparation methods, data collection protocols, and image processing strategies
