Projects

A selection from our projects

PLD4Energy

Metal-oxide thin films have promising applications in many energy devices such as batteries, solar cells and electro-chemical cells. Hence, the Dutch Institute For Energy Research (DIFFER) has commissioned the development of a state-of-the-art pulsed-laser deposition research cluster for energy research (PLD4Energy). The research cluster contains multiple ultra-high vacuum deposition chambers to grow films up to 4" in diameter.

Researchers have access to a variety of conventional and novel in-situ diagnostics to determine material properties such as film stoichiometry, composition, thickness, opto-electrical properties and structure in real-time. This allows for fast optimization of growth recipes and better control over the deposition process.

The back-bone of the research cluster is being realized by DEMCON TSST, while separate diagnostics are being realized by third party companies.

As Ratio, we fulfill the role of system architect from initial idea, through conceptual design, tendering, detail design, testing and operational usage over a period of five years.

SMART*Light

SMART*Light is an innovative table-top synchrotron for coherent high-brightness X-rays being developed at the Eindhoven University of Technology. These X-rays have highly desirable properties required in the development of new medicines, new materials for the energy transition, and the study and conservation of cultural heritage.

The x-ray source is based on inverse Compton-scattering. That is, when ultra-short laser pulses (30 femto seconds) interact with bunches of electrons traveling nearly at the speed of light, the electrons emit X-rays.

With this project Ratio cooperates with TU Delft, Eindhoven University of Technology, University of Antwerp, Ghent University, Materials innovation institute (M2i), DIFFER and VDL ETG Technology & Development B.V. The project runs for three years from the 1st of September until the 31st of Augustus 2026.

MultiWaterWerk

In the coming decades, Rijkswaterstaat (RWS), the executive branch of the Dutch Ministry of Infrastructure and the Environment, has to replace or thoroughly renovate more than dozens navigation locks. Given the substantial number of locks that needs to be renewed in a relatively short time frame, Rijkswaterstaat is developing a productplatform for navigation locks to reduce the project duration and costs while improving the performance of their assets.

The productplatform enables one to quickly configure navigation locks and generate systems specifications that dictate which requirements apply for that specific configuration.

Ratio is involved in all aspects of the development of the productplatform. That is, the development of the underlying data model, the platform architecture, implementation and maintenance.

Nuclear Ecosystem Mapping

Strong innovation and technology ecosystems are key to tackling future challenges, but their development requires well-targeted policymaking. Since these types of ecosystems are complex in many facets, they need systematic approaches to understand them. The Nuclear Ecosystem project uses systems engineering methodologies to map various aspects of both the current and envisioned Dutch nuclear ecosystem, from which technology opportunities and strategic collaborations are found.

The project is a collaboration with DIFFER and ILO-NET, and supported by companies in the nuclear domain.

Optimal Maintenance

Rijkswaterstaat (RWS), the executive branch of the Dutch Ministry of Infrastructure and the Environment, maintains a heterogenous portfolio of locks throughout the Netherlands. Scheduling maintenance with minimal hindrance for waterborn traffic is non-trivial due to the large spread in expected life-time of components of locks and bridges. Ratio is involved in developing an algorithm to schedule maintenance procedures from a network perspective to efficiently synchronizing (or desynchronizing) maintenance activities within and across locks within the portfolio.

DICE

Molten salt reactors are emerging as a promising candidate for next-generation nuclear reactors. The materials in these reactors must be able to withstand corrosive and nuclear environments for a long time period. The DIFFER Irradiation-Corrosion Experiment (DICE) is a world-first capability, where materials are exposed simultaneously to irradiation and molten salt. It replicates the high temperature and high radiation conditions found in a molten salt reactors. Using a high-power ion beam, the effects of long-term radiation exposure can be reproduced in a shorter timeframe, giving a unique insight into material performance and durability.

The DICE project is a collaboration with DIFFER. Ratio is involved in the improvement of the current DICE setup and the conceptual design of DICE 2.0.
