Paper Abstract

A new clean room facility is in progress at the Division of Solid State Physics / Nanometer Consortium (FTF) at Lund University. On site measurement from road excitation at a speed bump located at a distance of 25 m from the site and from main roads situated at a few hundred meters distance revealed high vibration levels. A complicating matter was found in high lateral vibration levels at the 4 Hz range. Various set ups using piling and dig out were investigated and found not to improve the situation. A vibration isolation system with very low natural frequency was found to be the only way left to use the site. A modular set up has been used such that the system can be either 1-stage isolated or 2-stage isolated.
