The assignment:

Setting/background

VDL co-develops charged particle systems together with multiple customers, like electron microscopes, chemical analysis equipment and particle accelerators.

In all these systems, a vacuum environment of a certain quality is critical for the function of the system. As a result there is a need for connecting signals through a vacuum boundary, like a vessel wall or a flange on the vessel. These signals can be electrical or (fiber)optical, where the electrical signal usually can be grouped into three categories: High-Voltage (with different classes e.g. < 5 kV, < 50 kV, < 100 kV etc.), High-Speed (requires e.g. impedance control) and general signals for sensors, heaters, actuators etc.

Problem statement

Currently, in high-tech manufacturing, there is a growing demand for these type of systems, especially e-beam based inspection, diagnostic and writing equipment. One strong market trend is that these systems are often designed with multiple active columns in one vacuum environment, which usually make the requirements on signal integrity, shielding, etc. more stringent.

As a result, the amount of signals that needs to be fed through the vacuum barrier increases dramatically, while vacuum requirements remain tight, or become even tighter. Since available space on a vacuum vessel for feedthroughs is usually limited, this leads to big design challenges.

The current state-of-the-art for feedthrough manufacturing is usually not suitable for a combination of:

⦁ very high signal counts (up to several 1000 connections)

⦁ maintaining (Ultra)-High-Vacuum boundary conditions (10-8 - 10-10 mbar)

⦁ low volume/space/surface area required

VDL is looking for novel solutions to overcome these technology barriers in three areas:

A. High voltage connections, up to 50 kV

B. High speed signals that require impedance controlled transmission line properties (https://en.wikipedia.org/wiki/Impedance_matching)

C. High density fiber optical connections

Assignment for option A, B or C

⦁ Perform an investigation of available theory, regulations/norms and existing manufacturing technologies

⦁ Make one (or several) design proposals that can be manufactured with technology that is available within VDL, or its strategic suppliers

⦁ Design a prototype or functional model for one of these solutions

⦁ Execute experiments to validate the design and to define the process parameters of the manufacturing

Who are we looking for?

⦁ You are an Master Mechanical Engineering student looking for a graduation assignment

⦁ You have a passion for technology and want to make a real impact

⦁ You are driven, ambitious, entrepreneurial and eager to learn

⦁ You are motivated and know how to work on your assignment both independently and in a team

What do we offer?

⦁ Lots of room for your own input

⦁ You are part of the international, industrial family business VDL Groep, where continuity is of paramount importance

⦁ Working together in a professional manner in an informal, no-nonsense environment where open communication prevails

⦁ Ample opportunity for personal development and entrepreneurship

⦁ A generous internship remuneration

⦁ An annual VDL party with all colleagues of the VDL Groep.

⦁ Staff offers
