fei titan g2 80-200 crewley @er-c

The FEI Titan G2 80-200 CREWLEY is a remotely operated field emission gun (scanning) transmission electron microscope equipped with a high-brightness Schottky field emission electron gun, a monochromator unit, a Cs probe corrector, a Super-X EDX system, an UltraScan 1000XP-P charge coupled digital camera, an on-axis bright-field/dark-field STEM detector as well as a Gatan Enfinium ER (model 977) spectrometer with DUAL EELS option allowing a simultaneous read-out of EDX and EELS signals at a speed of 1000 spectra per second.

The Titan G2 80-200 CREWLEY is characterised by a STEM resolution of 80 pm and TEM information limit of 110 pm at 200 kV. Basic specifications for the instrument are given below.

Microscopists planning to use this instrument should contact András Kovács or Roland Schierholz.

Users of the Titan G2 80-200 CREWLEY are kindly asked to quote a tecnical description of the instrument published in the Journal of large-scale research facilities 2 (2016) A43. http://dx.doi.org/10.17815/jlsrf-2-68 when referring to the use of this instrument in publications.
