NSLS-II Vibration Analysis

Nick Simos is responsible for the vibration stability analysis of the NSLS II conventional as well as experimental facilities. Nick’s responsibilities include the collection and analysis of pertinent field vibration data at the NSLS II site and other facilities as well the modeling of vibration propagation and its interaction with the NSLS II facilities required to meet stability criteria.

Nick is a member of the BNL scientific staff and has been with the Lab for 18 years. He has been the principal investigator in a wide spectrum of research and technical projects including the earthquake safety of nuclear facilities and accelerators, the stability of geostructures and the design and delivery of accelerator systems such as the collimating structures of the Spallation Neutron Source. In recent years Nick has led a series of comprehensive studies for the Department of Homeland Security and other agencies addressing the vulnerability of the national critical infrastructure through state-of-the-art modeling and simulation of large-scale, extreme events. Nick has also been a team member in several high power accelerator experiments focusing on the interaction of intense proton beams with targets. He has led a DOE-funded experimental research on radiation damage of critical accelerator components including production targets, collimating structures, detector components, etc. Nick has also been an adjunct professor of engineering at the graduate schools of Polytechnic Institute of New York and the City College of CUNY in the areas of Vibration, Finite and Boundary Element Analysis and Earthquake Engineering.

Nick holds a degree in Naval Architecture from the Technological Educational Institute of Athens, Greece, a Bachelor and a Master of Mechanical Engineering from the City College of CUNY, and a PhD in applied mechanics from the City University of New York. He is a Professional Engineer (PE) with the State of New York.
