| Magic number captures complex plasma behavior |
|
|
What if extremely complex behavior could be captured with simple mathematics? To his surprise, John Sheil and his team members, managed to do exactly this. In collaboration with researchers from ASML in San Diego, they discovered that the average charge state of the plasma consistently scales with the kinetic energy raised to the power of 0.4. Do you want to know more about this 'magic' number?

| Farewell symposium for Stefan Witte |
|
|
On February 26th, 2025, ARCNL and Vrije Universiteit Amsterdam will organize a public farewell symposium on the occasion of the departure of ARCNL/VU group leader Dr. Stefan Witte. He accepted a new position as full professor in the Imaging Physics Department at the Faculty of Applied Sciences, Delft University of Technology. Stefan has been with ARCNL since its start ten years ago, witnessing and contributing to a remarkable period of growth. He now looks forward to starting a new phase in his career.

PhD defenses full steam ahead
|
| A new tradition: the Theses Wall |
|
|
Upon completing their doctoral trajectory, PhD students at ARCNL add a metal tile featuring their thesis cover to the Theses Wall at the entrance of the Matrix VII building. Over the past few months, three ARCNL researchers had the honor of contributing to this tradition. The first to take the stage was Klaas Bijlsma, followed by Alessandro Troglia (see photo) and Xiaomeng Liu.
- Klaas Bijlsma, ‘Electron capture in collisions of tin ions with molecular hydrogen’
- Alessandro Troglia, ‘Optimizing thin-film properties via atomic-scale modification’
- Xiaomeng Liu, ‘Spectrally resolved Extreme Ultraviolet Lensless Imaging With High-Order Harmonic Generation Sources’

'Wetenschapsdag' attracts diverse public
|
|
|
| On October 5th, ARCNL joined other organizations at Amsterdam Science Park to celebrate science with a broad audience. Children experimented with friction and created their own light-separating devices, while others attended lab tours and lectures. Wetenschapsdag is an annual event held as part of the national Weekend of Science. |

Light source technology in the spotlight
|
|
|
|
Light source technology is at the heart of the computer chip revolution. Researchers in this exciting field gathered in Amsterdam for the Source Workshop, held from October 21st to 23rd. The workshop focused on the latest scientific and technical advancements in extreme ultraviolet (EUV) and soft X-ray sources. It was organized by ARCNL and EUV Litho. Curious about the speakers?

| High Harmonics unveil fascinating features |
|
|
| The research group led by Peter Kraus brings exciting news for those studying extremely small structures. Kraus and his team use a technique called High Harmonic Generation (HHG) to produce light with ultra-short wavelengths that could make tiny structures (around 100 nm) visible. Advancements have been made to observe much smaller structures and also in more complex geometries, particularly in solids. Do you want to know more about the publications? |
