PhD ‘Real-time contact-less vibration detection in lithography systems’(V35.1320) in the section Dynamics and Control of the Department of Mechanical Engineering The Department of Mechanical Engineering considers as the core of their activities design, realization and analysis of new products, processes and materials. Besides the basis of (solid and fluid) mechanics, materials, control and thermodynamics, parts of mathematics, physics, chemistry and computing science are important supporting tools. The field is explored by a combination of modeling using fundamental concepts and applied engineering and technology. Automotive Engineering Science and Micro- amp; Nano-Scale Engineering are important departmental themes. The Mechanical Engineering Department comprises about 1000 students and 250 staff members. In the section Dynamics and Control of the Department of Mechanical Engineering, research is focused on the sub-areas nonlinear dynamics, engineering acoustics and noise control, nonlinear control and robotics, structural optimization and vehicle dynamics. The present vacancy plays a key role within the sub-area on engineering acoustics and noise control. Besides contributing to the teaching of the master curricula in Mechanical Engineering, also research in the area of engineering acoustics and acoustic signal processing is expected from the successful candidate. Eindhoven University of Technology has a PhD vacancy at the Department of Mechanical within the project “Real-time contact-less vibration detection in lithography systems”. This project is a collaboration between Eindhoven University of Technology, and the companies ASML and SORAMA. ASML is the world leading manufacturer of lithography systems for the semiconductor industry, while SORAMA specializes in high-precision acoustic imaging systems. The project concerns the development of a real-time contact-less distributed vibration detection system, with particular focus on lithography applications. Project description: The PhD position is aimed for design and application of a real-time contact-less distributed vibration detection system based on Near-field acoustic holography (NAH). NAH is a well-known sound source identification technique based on measurements with an array of microphones on a plane (hologram plane) close to the source surface. The array data is then transformed to obtain not only the sound pressure but also the vibration velocity distribution on the source surface. This makes NAH a potentially powerful method for contactless vibration detection. The goal of this PhD project is to extend the NAH formulation to confined spaces and investigate the potential of acoustic array measurements for distributed vibration detection in lithography systems, both numerically and experimentally. For successful accomplishment of the project, a PhD candidate must address problems of sound wave propagation, acoustic field modeling in confined spaces, acoustic signal processing and inverse acoustics. The PhD student will work in close co-operation with the companies, which are responsible for the embedded system development and its application in motion control. Requirements A candidate for this challenging position should have a Master’s degree or equivalent in Mathematics, Electrical Engineering, Mechanical Engineering or in Applied Physics. He/she should have a strong interest in engineering acoustics and acoustic signal processing and affinity with embedded system design and motion control.
