Very often, the performance of modern electron microscopes is limited by the poor quality of the laboratory rather than by the specifications of the microscope. Therefore, with microscopes aiming at subangstrom resolution microscopy and highest performing holography methods, special measures have to be taken to reach the needed low level of AC-stray fields, vibrations, and acoustic noise. in an ”organically“ grown institute, this is very difficult to realize, if possible at all.

• The Triebenberg Lab is newly built well outside the city of Dresden, in an area essentially free from disturbances, i.e. free from power lines, away from roads, trains and airplanes; fortunately, the site is shielded from wind by means of a dense belt of trees. The lab houses six microscope units each consisting of a microscope room, a room for peripheral devices (power supply, cooling units, computers, etc), and an office for up to three scientists. in view of the nearly ideal environment, the main challenge is to avoid any self-made disturbances which might arise by the operation of the lab. Therefore, without any compromise using the best art of engineering, we designed a special lab virtually free from disturbances. in the following, the main guidelines for the construction are sketched.
