Summary
A new low vibration laboratory for microscopy was constructed using a 100-ton floating foundation on air springs. This advanced system achieves extremely low vibration levels, ideal for sensitive microscopy applications.
Area of Science:
- Engineering
- Physics
- Materials Science
Background:
- Microscopy applications demand exceptionally low vibration environments.
- Existing laboratory spaces often fail to meet stringent vibration isolation requirements.
Purpose of the Study:
- To detail the construction and vibrational performance of a novel low vibration laboratory.
- To achieve vibration levels suitable for advanced microscopy.
Main Methods:
- Construction of a 100-ton floating foundation supported by passive pneumatic isolators (air springs).
- Foundation rests on a 200-ton solid base plate.
- Optimization of the air spring system.
- Implementation of a room-in-room concept for acoustic and electromagnetic isolation.
Main Results:
- The optimized air spring system achieved vibration levels below 10 nanograms (ng) of acceleration for most frequencies.
- The laboratory provides significant acoustic and electromagnetic isolation.
Conclusions:
- The designed low vibration laboratory effectively meets the demanding requirements for sensitive microscopy.
- The combination of a floating foundation, pneumatic isolators, and a room-in-room concept provides superior vibration, acoustic, and electromagnetic isolation.
