Abstract
A variable temperature atomic force microscope (AFM) is being built at Houghton. The AFM will use a spring vibration isolation system with eddy current dampening in order to remove mechanical vibrations from both the machine and external sources. To approach and scan a sample, a modified “Johnny Walker” beetle will be built to move up, down, and across a ramp. Liquid nitrogen and resistive heating will be used to create a range of ~100K – 500K to measure in and increase the temperature range of the AFM.
