The Eyes of Photon Science: Imaging, Simulation and the Quest to Make the Invisible Visible
Science advances by extending our senses beyond the limits of human perception, pushing the boundaries of what we can observe. In photon science, imaging detectors serve as the eyes of science, translating invisible processes into measurable and analysable data. Behind every image lies a deep understanding of how detectors see, respond and perform.
At facilities like the European XFEL, the world's most powerful X-ray free-electron laser located in the Hamburg metropolitan area, imaging detectors capture ultrashort X-ray flashes at MHz frame rates and with high dynamic range. Without these advanced detectors, even the brightest X-ray laser beam would remain invisible. They help to reveal what would otherwise stay hidden, such as the structure of biomolecules, the behaviour of novel materials, and matter under extreme conditions. But how do we know they will perform as expected? And how do we design systems capable of “seeing” the invisible?
I will take a closer look how imaging technology in large-scale facilities is simulated and designed to make the invisible visible. From predicting detector performance to evaluating image quality, we look at how performance simulation helps scientists and engineers understand the “eyes” of modern science.
X-ray imaging detectors have come a long way in the last 15 years, turning ideas that once seemed impossible into realities. Imaging detectors in photon science are more than just high-speed cameras. They are complex systems operating at the limits of what’s physically measurable. Understanding how they behave before, during, and after experiments is essential to advancing both the technology and the science it enables.
In this talk, I’ll take you inside the world of detector simulation and performance modelling. I’ll explore how tools like Monte Carlo simulations, sensor response models, and system-level performance evaluations are used to:
- Predict detector behaviour in extreme conditions (such as MHz X-ray bursts), and
- identify critical performance bottlenecks before production.
By linking imaging technology with simulation and modelling, we can better interpret experimental data and design the next generation of scientific cameras. Beyond the technical aspects, this talk reflects on the broader theme of how we “see” though technology, what it means to make the invisible visible, and how simulation changes not only how we build instruments, but also how we understand them.

Despite how it's often portrayed in blogs, scientific articles, or corporate test planning, fuzz testing isn't a magic bug printer; just saying "we fuzz our code" says nothing about how _effectively_ it was tested. Yet, how fuzzers and programs interact is deeply mythologised and poorly misunderstood, even by seasoned professionals. This talk analyses a number of recent works and case studies that reveal the relationship between fuzzers, their inputs, and programs to explain _how_ fuzzers work.

Die Legalisierung des Online-Glücksspiels in Deutschland im Jahr 2021 und die zunehmende Normalisierung von Glücksspiel und Sportwetten in den Medien haben ein Umfeld geschaffen, in welchem Glücksspielprodukte leichter zugänglich und gesellschaftlich stärker akzeptiert sind als je zuvor. Diese weit verbreitete Exposition birgt erhebliche Risiken für vulnerable Personen, insbesondere da die Grenzen zwischen Spielen und Glücksspiel zunehmend verwischen. Seit einiger Zeit ist beispielsweise ...

Did you ever wonder where all the drugs, which you can get at a pharmacy, come from? Who makes them, and how? Well, there is no easy answer, because the process of drug discovery and development is a very complex, expensive, and challenging journey, riddled with many risks and failures. This holds true for all types of drugs, from a simple pill to an mRNA vaccine or a gene therapy. Today, scientists support this process with a variety of AI applications, cutting-edge technologies, automation, ...

Zur Überraschung Vieler sind Juristen Wissenschaftler, die nach wissenschaftlichen Maßstäben arbeiten sollten und ihre Schriftsätze und Urteile auch nach stringenten wissenschaftlichen Kriterien gestalten und untereinander diskutieren sollten. Doch nur in einigen Rechtsgebieten funktioniert dies. Wie jede Wissenschaft ist auch die Rechtswissenschaft nur so gut wie das ihr zugrundeliegende Quellenmaterial – in diesem Fall sind das meist Urteile. Empirische Untersuchungen über diese Daten ...

It is 1976 and the USA long stopped going to the Moon when a Soviet automatic landing station called Luna 24 descends to the Lunar surface. It touches down on 3.3 Billion year old rock formations at a place no mission has ever gone before. What exactly happened remains a mystery to this day, but the space probe managed to take a 2.3 m long drill core from the Lunar regolith, packaged the sample in a genius way and launched it for its voyage to Earth. Some days later the sample entered earths ...

**Over the past few decades, nucleic acids have increasingly been investigated as alternative data storage media and platforms for molecular computing. This talk builds on past research and introduces another branch to the field: DNA cryptography based on random chemistry. This technology provides a platform for conceiving new security architectures that bridge the physical with the digital world.**

Der Trend geht dahin, aus Gesundheitsdaten große zentralisierte Datenbanken aufzubauen. Eine datensparsame Alternative dazu ist, in einem verschlüsseltem Netzwerk gemeinsam auf verteilten privaten Daten zu rechnen, ohne sie miteinander teilen zu müssen. Perspektivisch können so demokratischere Datenströme geschaffen werden, die Patient:innen als aktiv Teilhabende statt als passive Datenquellen einbinden. Kommt mit auf eine Reise, die vor sechs Jahren in Deutschland gestartet ist und jetzt ...
