Are you a master student with a background in Physics, Computer science, Mechanical Engineering or Mathematics? Are you familiar with Python and do you have strong drive for ownership? Then this internship could be interesting for you!

Background Information

In the past, ASML has investigated whether a free electron laser would be a suitable light source for our products. As a spin-off, another application was identified in which the same technology can be used to generate radioactive isotopes for medical diagnostic procedures (i.e. for SPECT scans). Since 2018 ASML is partnering with the Institut National des Radioéléments (IRE) in Belgium, to realize a facility that can come to an industrial production of molybdenum-99. In essence an electron beam is irradiating a molybdenum-100 target. The current of this electron beam, in combination with the irradiation duration, are optimized by using a production planner in order to meet the daily demand. This production planner has been written in Python and it contains several different strategies that enable a day to day optimization.

Your Assignment

During this internship it is important to:

  • Become familiar with the known physical processes that take place in the generation of molybdenum-99;
  • Familiarize yourself with the current production software framework;
  • Invent and implement new irradiation strategies and test/model their performance;
  • Set as goal to optimize the molybdenum-99 production in the actual production phase of the facility.

Your Profile

  • You are a master student with a background in Physics, Mathematics, Mechanical Engineering or Computer Science;
  • You are familiar with Python;
  • Strong drive for ownership and self-propelling ability is highly essential;
  • The English language is required both written and verbally.

This is a full-time master apprentice internship with a duration of minimum of 6 months. The start date is as soon as possible.

Please note that we can only consider students who are enrolled at a school for the entire duration of the internship.

Other information

What ASML offers
Your internship will be in one of the leading Dutch corporations, gaining valuable experience in a highly dynamic environment. You will receive a monthly internship allowance based on your educational level and number of days per week, plus a possible housing or travel allowance. More information on the allowances can be found on our website. In addition you will get expert, practical guidance and the chance to work in and experience a dynamic, innovative team environment.

ASML: Be part of progress
We make machines that make chips – the hearts of the devices that keep us informed, entertained and safe; that improve our quality of life and help to tackle the world’s toughest problems.

We build some of the most amazing machines that you will ever see, and the applications to run them. Never satisfied, we measure our performance in units that begin with pico or nano.

We believe we can always do better. We believe the winning idea can come from anyone. We love what we do – not because it’s easy, but because it’s hard. At ASML we are always pushing technology further.

Students: Getting ready for the real-world
Teamwork is key within ASML. Our R&D team is more than 5,500 people strong and worldwide we form one big team with over 25,000 employees. These colleagues have 123 different nationalities and work at our major sites on three continents.

Dozens of diverse, interdisciplinary teams work in parallel to meet a challenging development schedule. In this inspiring environment, your colleagues may be sitting next door, or they could be thousands of kilometers away in a different country, or even working for a different company.

An internship at ASML is your opportunity to get to know this world and get a feel for that excites you most. Use your education, gain real-life working experience and explore the world of high-tech – all at the same time.

How will you be part of progress?
