Freek Pols published a paper in the Electronic Journal for Research in Science & Mathematics Education. In this practitioner contribution, he elaborates on how the first-year lab course was adapted to the COVID-19 measures.

Daan Boltje joins Hoogenboom group as industrial PhD. Daan is an experimental physicist working at Delmic, who will join ImPhys for about 3 years to work on a so-called industrial PhD position.

The paper of Maurice Krielaart on "Miniature electron beam separator based on three stacked dipoles" has been highlighted as editor's pick in the Journal of Applied Physics.

De eerste detector-array voor NASA's GUSTO-missie heeft zijn pre-shipment review doorstaan en wordt nu naar de Universiteit van Arizona verzonden voor integratie in de ballontelescoop. SRON ontwikkelt samen met TU Delft de drie 8-pixel-arrays, voor de frequenties 4.7, 1.9 en 1.4 terahertz. Ze hebben nu de array voltooid voor het 4.7 terahertzkanaal—het lastigste onderdeel. GUSTO is een ballonmissie die de emissies gaat meten van materiaal tussen de sterren; het interstellaire medium.

Myelination is a crucial aspect of brain development and is essential for the functioning of the nervous system. Demyelination, on the other hand, is a pathological process that plays an important role in certain diseases such as multiple sclerosis. Accurate measurement of myelin content has the potential to increase our insights into several disease processes. Magnetic resonance imaging (MRI) enables imaging of features related to (de-)myelination in vivo. Martijn Nagtegaal uses dictionary matching and a joint sparsity multicomponent T2 fit to obtain MWF maps.

Although many on-campus activities were cancelled, the development of the new MAKERSPACE continues steadily. In this makerspace students can tinker and build prototypes.

TU Delft is setting up eight new AI Labs to investigate how artificial intelligence (AI) can accelerate scientific progress. With the IRIS-lab (Intelligent & Reliable Imaging Systems) the involved researchers David Maresca, Arjen J. Jakobi and Carlas Smith want to open the "black box" of AI and develop methodologies for context-independent, knowledge-based learning of imaging systems that will address fundamental challenges in all quantitative imaging applications.

Many of us are going through a difficult time at the moment. COVID-19 and the measures imposed by the Dutch government and TU Delft affect us all. Everyone is facing major challenges. We asked Dr Maria Sovago – lecturer in physics at the faculty of Applied Sciences – to share her experiences and best practices with us.

Bits&Chips published an article on the development of a multibeam SEM at ImPhys: "Medical and biological scientists are eager to create 3D images for their research at nanometer resolution. However, without an efficient technique to make the scan, the process is difficult and painfully slow. To make this research feasible, ImPhys/TU Delft is teaming up with a consortium of enterprises to develop and innovative device: a multibeam scanning electron microscope".

The paper introduces a new rigorous method to solve electromagnetic scattering problems in the strong scattering regime. Conventional methods such as FDTD, FEM or integral equation methods require computing the solution of a very large set of linear equations.
