iStOMPS at the Lange Nacht der Forschung 2024

On 24.05.2024, the Lange Nacht der Forschung (Long Night of Research) commenced in Austria. Lorenz, Rahul, and Sebastian from iStOMPS participated in this fantastic event with an exhibit at the main building of the University of Vienna. Together with members of the Backus group (laser spectroscopy), they presented a hand-built, do-it-yourself-style absorption spectrometer for visible light. We (and the visitors) had lots of fun in discovering how colors work. There even was a detective story about the ominous Prof. U. V. Vis for the kids to solve!

The spectrometer consists of easily available parts: an LED torchlight, a reading lens, two playing cards, a simple optical grating, a strip of white paper, and a webcam. The parts are arranged on a plywood frame with some 3D-printed mounts and contained in a black cardboard box that can be closed. When the torchlight is turned on, its light falls on the grating and is split into a rainbow on the paperstrip. The webcam sends pictures of the rainbow to a connected laptop that visualizes the absorption spectrum of colorful foils or table scatter gemstones.

Visit at the Paul Scherer Institute

From 21 to 27 November 2023, I visited Dr. Xinhua Xie, one of our project collaborators, at PSI (Switzerland). On the one hand, during that week I participated in an experiment on X-ray-induced Augen ionization of molecules. On the other hand, I learned a lot of background information about free electron lasers (FELs). In addition to academics, the SwissFEL and SLS tour guided by Dr. Xinhua was also very impressive.

iStOMPS goes (to the) wild (boars)

On July, 12th our team enjoyed a beautiful sunny summer day going hiking in one of the last pieces of the original Viennese Woods – that is the Lainzer Tiergarten (or Zoo), located on the outskirts of the city. Equipped with some good sandwiches and a lot of fun and joy, we made a “big round” in this special recreational area. Since Ale lives in Hütteldorf, as a local, she proposed the following route (highlighted below), entailing some nice panoramic view points, such as the “Hubertuswarte” (see first picture below) and the “Kaiserwiese” (second picture).

The Lainzer Zoo offers a unique natural landscape with a wealth of flora and fauna — e.g., there are generally lots of wild boars — as well as cultural-historical exhibitions in the Hermesvilla. In other words, it is a place that offers relaxation, experience in nature and education and, as you can judge from our smiles, our iStOMPS team enjoyed this excursion very much!

iStOMPS goes Salamanca

From 7.2.2023 to 22.2.2023 I was performing a research stay in the group of our collaborator Prof. Carlos Hernández-García at the University of Salamanca (Spain). Together with Rodrigo Martín-Hernández, a PhD student of his photonics group, I was performing further scans for the magnetic field enhancement and electric field suppression of different aperture shapes. Besides science, I also had the opportunity to do little sightseeing tours in the marvellous city of Salamanca and try out my (basic) Spanish speaking skills.

Gracias por la agradable estancia a mis queridos colegas Carlos y Rodrigo y a iStOMPS!

Stimulated Raman scattering in the News

The ACS Photonics article published by Edgar Kaksis and Valentina Shumakova about stimulated Raman scattering for the production of XUV radiation produced quite a lot of Media attention. Have a look for yourself at the News page of the TU Wien Faculty of Electrical Engineering and Information Technology!
