The Dual Beam FEI Helios | The Dual Beam FEI Helios nanoLab 600 consists of two independent charged particle sources: 1- electrons, 2- gallium ions (Ga+). FEG-SEM with versatile characterization capabilities. At the time being, this microscope SEM provides highest resolution among all operational SEMs at DTU-Cen, when operated for high resolution imaging (i.e. using low kV , in-lens detector, and in immersion mode). This microscope is equipped with the following detectors BSE (backscatter electrons), [http://en.wikipedia.org/wiki/Electron_backscatter_diffraction electron backscatter diffraction (EBSD)] (backscatter diffraction pattern), [http://en.wikipedia.org/wiki/Energy-dispersive_X-ray_spectroscopy Energy-dispersive X-ray spectroscopy (EDS)] (X-Rays), CDEM (secondary ions), etc. | ||
Gal+ focused ion beam (FIB) provides the possibility of characterization of microstruture by imaging and serial sectioning via sputtering. Since the microscope is equipped with a micro manipulator for high quality TEM sample preparation. | Gal+ focused ion beam (FIB) provides the possibility of characterization of microstruture by imaging and serial sectioning via sputtering.

'''Irregardless of their prior experience any new user with no official DTU Nanolab training or approval cannot operate the instrument, not even under close supervision by experienced users. | ||
*'''Users may only use the instrument to the extent they have been trained.''' This means that one should not try to operate the following options/capabilities without explicit training: | *'''Users may only use the instrument to the extent they have been trained.'''
