Abstract/Summary
Scanning Tunneling Microscopy (STM) works by scanning a fine metal wire over a conductive sample in order to image samples on the atomic level. The microscope uses a feedback loop with a PID controller to maintain a constant tunneling current between the sample and the tip. In order to obtain clear imaging at the atomic level, the microscope and the sample need to be isolated from external vibrations in a vacuum chamber. The scope for this project is to build and test a single-stage vibration isolation system that effectively attenuates the amplitude of external vibrations acting on the microscope. This document summarizes the preliminary design process, including the customer interviews we performed, the background research we collected about existing patents and designs, and the technical journal articles dealing with this subject that we read. In addition, this project defines the final design along with manufacturing and testing results to validate the design. The final design includes a final design description, design justification, manufacturing results, as well as the testing plan and results. These sections serve to overview the process for our final design selection and the results of the manufacturing and testing phases of the final design.
