Open for Collaboration

Short Description

The transmission electron microscope (TEM), which is equipped with a cold FEG electron source (energy dispersion of 0.3 eV), can image both inorganic and organic sample structures down to the sub-nanometer range (TEM: 0.08 nm & STEM 0.15 nm). The TEM can be operated at acceleration voltages of 60 kV, 80 kV, and 200 kV, making it suitable for the examination of biological and radiation-sensitive samples. The instrument has two 4k x 4k cameras. The microscope is characterized by the high brightness of the electron source, the large solid angle of the windowless EDX detector (almost 1 steradian), a backscatter and secondary electron detector, and the ability to capture high-resolution images with elemental contrast using the High Angle Annular Dark Field (HAADF) detector.

The equipment with a CEFID energy filter additionally enables the recording of energy loss spectra (EELS) and elemental distributions as well as contrast-enhanced images. This allows, among other things, the improved visualization of low-contrast structures, such as biological systems. The microscope is equipped with a cryo-plunger and a cryo-transfer holder, so that samples in aqueous medium or radiation-sensitive samples can be prepared and observed.
