The Nova is, in it's normal configuration, a very versatile characterisation instrument. Capable of producing enlarged images of a variety of specimens and achieving magnifications of over 500.000 times with ultra high resolution imaging in both high and low vacuum. The Nova has become highly evolved in it’s life at DTU Nanolab and it is possible to carry out advanced processes including in-situ experiments using heat, gas injection and probing. At the time being this microscope is mainly designated for advanced microstructural characterisation and particle analysis techniques using [http://en.wikipedia.org/wiki/Electron_backscatter_diffraction electron backscatter diffraction (EBSD)] ,[http://en.wikipedia.org/wiki/Energy-dispersive_X-ray_spectroscopy Energy-dispersive X-ray spectroscopy (EDS)] and forward scatter electron imaging by detectors recently bought from [http://www.bruker.com/ Bruker]. | |||

*'''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.'''

When one combines the 6 different detectors, 2 vacuum modes and 3 SEM modes with the traditional SEM parameters such as high voltage, working distance, spot sizes etc. it is clear that the FEI SEM has a huge number of different ways to be operated in. The number of ways that produce ultra high quality images is, however, limited. It is therefore crucial that the operators share their knowledge of how to obtain great images. | When one combines the 6 different detectors, 2 vacuum modes and 3 SEM modes with the traditional SEM parameters such as high voltage, working distance, spot sizes etc. it is clear that the FEI SEM has a huge number of different ways to be operated in.
