fei titan g2 60-300 holo @er-c

The FEI Titan G2 60-300 HOLO is a field emission gun transmission electron microscope designed for electron holography and in situ TEM analyses. The instruments is equipped with a high-brightness electron gun, an objective lens with an ultra wide pole piece gap, an imaging spherical aberration corrector element, a post column energy filter system as well as a system of two electron biprisms.

Digital images are to be taken with a Gatan 2k slow scan charged coupled device camera system. Specifications for the instrument operated under optimum conditions are given below.

Microscopists planning to use this instrument should contact Vadim Migunov or Amir Tavabi.

Users of the Titan G2 60-300 HOLO are kindly asked to quote a tecnical description of the instrument published in the Journal of large-scale research facilities 2 (2016) A44. http://dx.doi.org/10.17815/jlsrf-2-70 when referring to the use of this instrument in publications.
