Electron microscope vibration is an increasing concern in modern laboratories because of improving resolution and extended duration imaging. At higher resolution, external vibrations have a proportionally greater impact on image quality. Also, extended duration imaging and 3D reconstructions cause image quality to be more susceptible to incremental sources of vibration

Active vs. passive vibration isolation, understanding the difference is critical to mitigating the impacts of vibration on equipment performance. Passive isolation systems use the natural properties of a spring and a dampener to reduce vibration.

Vibration Criteria Curves, or VC-Curves, are a standard way to report vibration. They are helpful because they allow users to compare vibration levels across locations using a standardized, widely accepted format. However, electron microscopes

An EMI cancellation system cancels electromagnetic interference (EMI) that degrades electron microscopes performance. Using a sensor, controller, and field canceling loops, the EMI cancellation

DC and AC magnetic fields create electromagnetic interference (EMI) that can degrade the performance of electron microscopes and e-beam lithography tools. Although AC and DC magnetic fields are related, each impacts equipment differently.

Lawrence Berkeley National Laboratory (LBNL) is a national laboratory located in Berkeley, CA, with a focus on bringing together multidisciplinary teams of researchers to advance scientific discovery.
