Introduction to the job

ASML's Development & Engineering (D&E) sector is responsible for the specification, design and integration of the ASML machines. In this sector, the department of Machine Conditioning (MC), specifies, designs and does the functional integration of the various (sub-)modules and architectures related to the flow and thermal domains. The department consists of discipline- and function oriented groups where emphasis lies on particular knowledge/skills, architecture or modules in ASML machines.

Your assignment

EUV systems use hydrogen (H2) for several reasons. The Gas Facility Unit (GFU) is a cabinet that regulates H2 flow from bulk in a controlled manner towards the EUV system. These cabinets are build, tested and qualified (on cabinet level) at the vendor. During these testing and qualification steps, nitrogen (N2) is used as test gas instead of H2.

It is less understood if testing with N2 gas predicts the behavior of the module well enough when it's operational with H2 gas.

The scope of this apprentice internship is to improve understanding on how testing with N2 gas predicts behavior of the module when in operation with H2.

Tasks may include, but are not limited to:

• Familiarize yourself with the module design and it's critical components for gas handling.
• Understand the current way of working.
• Theoretical Investigation on how well testing with N2 predicts module functionality when in operation with H2.
• Theoretical guidance from university counterpart.
• Depending on the outcome of above, come up with a strategy to experimentally validate theoretical findings.
• Report out on findings

This is a master's level internship lasting minimum 4 months with possibility to extend. For fulltime or 4 days per week (hybrid and onsite). Starting in September 2025.

Your profile

To be a good fit for this internship assignment, you are a master student in Mechanical or Aerospace Engineering, Applied Physics or a related discipline. Additional skills requirement:

• Able to analyze mechanical components.
• Affinity with Fluid Dynamics & Physical Transport Phenomena
• You are eager to learn, structured, independent with a pro-active attitude.
• Have good communication skills in English (verbal and written)

Other requirements you need to meet:

• You are enrolled at an educational institute for the entire duration of the internship;
