Applied Physics | Mechanical Engineering internship: acoustic source modeling
IntroductionWithin ASML's Mechanical Development and System Dynamics team in Veldhoven, you will contribute to advancing the understanding of acoustic disturbances in highly precise lithography systems. Acoustic loads can influence system performance, particularly in environments where accuracy and throughput are essential. This internship focuses on extending an existing reduced-order acoustic modeling framework by introducing stochastic acoustic sources. Through this Internship, you will combine theory, simulation, and validation to help improve acoustic disturbance modeling. If you are interested in computational acoustics, numerical methods, and signal processing, this internship offers an opportunity to work on a relevant and challenging research topic.Your assignmentIn this Internship you will investigate how stochastic acoustic sources, which have no known time relationship, can be represented within an existing reduced-order modeling framework. You will explore theoretical concepts, develop modeling approaches, and validate results using simulations and measurements. Your work will contribute to a more realistic representation of acoustic disturbances while maintaining computational efficiency. Your main responsibilities will be:Conduct a literature review on stochastic acoustic source modeling Develop modal descriptions for stochastic acoustic sources Investigate modeling approaches for point, line, and surface sources Implement stochastic source representations within a reduced-order framework Create and evaluate a modal stochastic source matrix Compare simulation results with experimental measurements Document findings and provide recommendations for future development This is a master’s thesis internship for minimum 9 months, minimum 5 days per week (3 days on-site). The start date of this internship is flexible from October 2026 onwards.Your profileTo be suitable for the internship, you: Are pursuing a master's degree in applied physics, mathematics, mechanical engineering, or a related field at a university Have an interest in computational acoustics and acoustic modeling Have basic knowledge of numerical methods and simulation techniques Have an interest in dynamic measurements and signal processing Have basic experience with MATLAB Are analytical, proactive, and able to communicate effectively in English This Internship is suited for students who enjoy combining theoretical research with practical validation. You will work alongside experienced engineers and researchers while contributing to innovative solutions for complex acoustic challenges. The internship provides an opportunity to deepen your technical expertise, broaden your research experience, and create meaningful impact within ASML's technology development environment. Through this Internship you will gain hands-on experience in advanced modeling techniques and contribute to future improvements in p...
