Appendix A: Setting Up the TT-AFM
A.1. Selecting a Location:
;".
Structural vibrations from a building's floor and acoustic vibrations can greatly reduce the resolution of an AFM.
Ideally, the AFM would be placed in a vibration-free environment, but this is typically not possible. A few tips:
•
- Set the AFM up in a building's basement or lower floor near a bearing wall.
- Avoid setting the AFM near fans or other sources wind turbulence.
- Avoid locations where there are elevators, a lot of foot traffic or freeways.
- If you must place the AFM in an undesirable location, consider purchasing a vibration table and/or
acoustic enclosure.
- A simple test to see if a location has a problem is to fill a coffee cup with coffee and set It in the
potential location. If there are ripples in the coffee's surface, there are going to be problems.

A.2. Setting Up the Optical Microscope:
•
The video optical microscope is essential for efficient
operation of the TT-AFM. After setting up the
microscope, we recommend spending some time to

operate it by viewing some samples.
a) Assemble the video microscope:

1) Attach the post to the X-Y translator using
four screws and a hex wrench.
2) Place the

3) Install the zoom tube/CCO camera.
4) Attach the USB cable to the CCO and
