Mechanical Engineering Internship: Design an indestructible aperture for 1um beampath

Be part of progress

Introduction to the job

The Source Laser Beam Delivery group is part of the Mechanical Development cluster, responsible for the design of different optical systems to guide laser beams with a wavelength of 10um and 1um. To be able to detect out of control laser beam alignment and to prevent human safety or machine damage incidents, laser safety apertures are placed in the beam path.

Role and responsibilities

The current design of the 1um safety apertures is based on the design of the 10um apertures that has been used for many years. It was accepted that these apertures would be damaged if they were hit by the laser beam and hence it was also accepted for the 1um system.
If there were apertures that would not be damaged during a hit, the availability of the system would be improved, which will have a positive effect on the costs of using the ASML scanner. In addition, there is a high probability that coating on 1um optics will be damaged as a result of a damaged aperture, so-called collateral damage, which only increases the costs during an incident.

The objective of this assignment is to find possible principles to get to an indestructible aperture for 1um as well as 10um wave length and to translate these possible principles into feasible implementations. The main deliverables for this internship are:

• Make an inventory of patents, common industrial solutions and investigations already done by ASML colleagues in the past years and gather this documentation properly.
• From the investigation select best principle that could serve both wave lengths and make a design only for the 1um wave length that is SIL-3 compliant.
• Build a test setup to validate the design.
• Make a test analysis report.

Education and experience

• Education: Master Graduation thesis level
• CAD experience and precision mechanics is preferred. Manufacturing knowledge is helpful and must be able to use standard hand tools to put together the test setup.

Skills

• Precision engineering, mechanical engineering, physics, basic electronics
• Multi disciplinary view is a must (Laser physics, LIDT, light/matter interaction, material knowledge, optics)
• Optomechanical knowledge is a preferred
• Knowledge of Construction Principles
• Solution oriented, communicative; hands-on mentality is required

Other information

• 5 days per week
• No non-EU students; students supposed to study in proximity to Eindhoven since frequent on-site work is needed

This position requires access to controlled technology, as defined in the United States Export Administration Regulations (15 C.F.R. § 730, et seq.). Qualified candidates must be legally authorized to access such controlled technology prior to beginning work. Business demands may require ASML to proceed with candidates who are immediately eligible to access controlled technology.
