Nanotech I: Site Parameters and Nanotech II: Case Studies and Trends

The first important steps for planning nanotechnology facilities include site and facility assessment to see if the nanotechnology can be performed on the site.  “One site does not fit all” might be a good way to approach planning for nanotechnology.  The research carried out in these facilities is highly sensitive to excessive vibration, noise, electromagnetic […]...

Centile Spectra, Measurement Times, and Statistics of Ground Vibration

Facilities for advanced technology—particularly nanotechnology—impose very stringent requirements on the quality of the site. Ambient ground vibrations are among the most critical factors to consider when selecting a site. Commonly-accepted vibration criteria are available and they, in turn, dictate many of the measurement parameters such as bandwidth, frequency range, etc. However, there are still many […]...

Vibration Data Representation for Advanced Technology Facilities

Vibration control in vibration-sensitive advanced technology facilities generally involves interaction between a vibration consultant and several other engineering disciplines. It is important that the other disciplines have a rudimentary understanding of the consultant's measurement methodologies and design approaches. Practitioners have developed a specialized analytical approach which shares some commonality with traditional civil engineering dynamics, but […]...

On Generic Vibration Criteria for Advanced Technology Facilities: with a Tutorial on Vibration Data Representation

Abstract The design of vibration-sensitive advanced technology facilities generally involves considerable attention to structural and mechanical aspects. In most cases, the vibration control measures contribute significantly to a facility’s cost. The selection of a vibration criterion for use in design is an important step in the design process. Many process equipment manufacturers have provided tool-specific […]...

A Review of Several Methods for Processing Vibration Data

For many areas of acoustics, standards organizations or regulatory bodies have mandated vibration or noise criteria and defined the appropriate processing methods. No such standards exist for vibration-sensitive facilities at this time except as defined by equipment manufacturers, facility owners, and/or vibration consultants. The existing criteria from these groups differ widely in form. This paper […]...
