Ch. 19. Air Temperature Controller Sec. 19.2. Parts List
C above the average room temperature.
The ATC is not designed as an environmental controller to drive the working temperature of the sample.
19.1.1. Good Practices
To get the most out of your Air Temperature Controller, please follow these guidelines (even if you
don’t own an ATC, they will improve your imaging stability):
• A laboratory with decent temperature control will always lead to improved imaging stability.
Typically a windowless room with air conditioning operating at all times is preferred.
• Do not place your Cypher AFM in strong air currents, such as from an air conditioning vent. If
you have no choice, fashion some sort of air deflector panel.
• It can take between 6 and 12 hours for all the metal and components of the cypher AFM to
thermally stabilize. Therefore the best approach is to always leave the Cypher AFM turned on
and the ATC regulating the instrument temperature. If you wish you can turn off the laser at night
to extend its lifetime, but note that there may still be a period of thermal drift even from turning
on the laser.
• Keep the enclosure door closed as much as possible. Only open it briefly when exchanging
samples or cantilevers.
• Keep critical items, such as spare cantilever holders, somewhere inside the Cypher enclosure. This
will ensure all parts are at the same temperature. Some people also leave the cantilever holder
changing station (see
Step 9 on page 21) inside the enclosure to prevent the cantilever holder from
cooling down during tip exchange. Needless to say, work quickly when replacing tips.
