    Presentation Title-

    Laboratory noise and vibration design for highly sensitivity Electron Microscopes and Quantum Computing facilities

    Presentation Synopsis-

    This paper presents recent experience for the design and construction of sensitive laboratories applying the vibration criteria and requirements of manufacturers for equipment which is used for micro and increasing nano scale imaging or quantification. Vibration sensitivity has long been recognised for sensitive equipment within laboratories. The Vibration Criteria curves or VC curves [1] are widely used for laboratory design with challenges associated with their interpretation. Different equipment manufacturers apply the VC curves and often apply subtle differences in their interpretation and usage in the validation of laboratory performance. The most sensitive equipment in laboratories generally include equipment such as Transmission Electron Microscopes, Scanning Tunneling Microscopes and the like.

     

    The vibration in a new, refurbished or existing laboratory will depend on many aspects including the building structure, ventilation equipment location and isolation, support equipment, human activity and external activity such as vehicle movement. There is the possibility of excessive vibration depends on all these variables and hence relies on coordination with multiple parties in the laboratory design process.

     

    In designing laboratories, the equipment and building vibration performance need to be understood. A typical laboratory design will include site surveys or measurements, engineering design, consultation with users, reference to manufacturer requirements, quality assurance inspections and commissioning. The presentation associated with this paper provides examples of design, construction and commissioning results.
