FEI Titan G² 60-300 Holo

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 Amir Tavabi or Yoshie Murooka.

Users of the FEI 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 when referring to the use of this instrument in publications.

Instructions

The operation instructions given below and on the subsequent pages are ment as guidelines and knowledge base. They do not replace the direct introduction to the microscope usage by the instrument officers or your project manager. There are many steps and pitfalls in the operation of this microscope that can seriously harm you or the expensive equipment.

Since the Holo microscope is a very complex machine, please do not edit the instructions below before discussion the changes with the instrument officers.
