A new set of generalised oscillator strengths for EELS quantification by UMünster and CEOS * 23.08.2023

Tabulated generalised oscillator strengths are necessary for the quantification of most core-loss edges in EELS. The collaboration between CEOS GmbH and L. Segger and H. Kohl from the University of Münster has recently produced the first publicly available GOS database, filling a decade old void. The new data cover more edges and have better sampling then previous one, and are also available to everyone, under a permissive CC-BY license. More information (as well as the data and source code) can be found on Zenodo.

The new data is already employed in the latest version of CEOS Panta Rhei, and will be supported in HyperSpy 2 thanks to our contributions, finally making available the tools for a transparent processing of EELS data to the TEM community and to the public.

The Dectris ELA hybrid-pixel detector is now available as an add-on for our CEFID imaging energy filter. * 13.03.2022

We are excited to announce that CEOS is now offering a DECTRIS ELA hybrid-pixel electron detector integrated in their energy filtering and imaging device CEFID. For more details see Dectris.

CEFID Ultra-Fast TEM * 23.12.2022

Researchers from University of Göttingen, Germany, use our imaging energy filter CEFID at a JEOL 2100F Ultra-Fast TEM to study light/electron interaction in integrated photonics chips by EFTEM with 0.8eV energy-selection slit and large field of view. Our spectrometer is equipped with a TVIPS XF416 CMOS camera as well as a ASI Cheetah TimePix detector. For more details see Nature publication.

Major Honour for Max Haider *27.05.2020

Max Haider has been awarded with the Kavli Prize 2020 in Nanoscience together with Harald Rose, Knut Urban und Ondrej Krivanek. In the announcement ceremony on May 28th 28.5.20 their pioneering work to enable humanity to see the structure and chemical composition of materials in three dimensions on unprecedentedly short length scales was honoured. Find more information on the website of the Kavli Foundation.

Janis Köster receives Harald Rose Prize 2019 *5.08.2019

As part of the ceremony marking the 52nd anniversary of the University of Ulm, Janis Köster received the Harald Rose Prize 2019. The university wrote on its website: "The 3000 Euro Harald Rose Prize went to Janis Köster. The young scientist studied defects in a two-dimensional material using high-resolution electron microscopy and carried out accompanying calculations. His Master's thesis, which he performed in the Electron Microscopy Group of Materials Science, lead directly to several publications. The prize is named after a pioneer in electron microscopy, Professor Harald Rose, who holds a senior professorship at the University of Ulm." One of these publications can be viewed under Electron-Beam-Driven Structure Evolution of Single-Layer MoTe2 for Quantum Devices . You can read a full press release by the SALVE team there.
