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.

Low-frequency and high-frequency vibration both have a significant impact on electron microscopy laboratories and high-tech manufacturing facilities. These two types of vibration stem from different causes and the strategy for mitigating vibration for each is also different
