The tiniest secrets of integrated circuits revealed

New research has demonstrated that the secrets of the tiniest active structures in integrated circuits can be revealed using a non-destructive imaging technique. The breakthrough required the efforts of an international team of scientists from JKU and Keysight Technologies (Austria), ETH/EPFL/PSI and IBM Research - Europe (Switzerland) and from UCL (UK).

Chern Number

Cherned up to the maximum

In topological materials, electrons can display behaviour that is fundamentally different from that in ‘conventional’ matter, and the magnitude of many such ‘exotic’ phenomena is directly proportional to an entity known as the Chern number. New experiments establish for the first time that the theoretically predicted maximum Chern number can be reached — and controlled — in a real material.

Analytical Research Infrastructures of Europe (ARIEs)

Analytical Research Infrastructures as key resources for the five Horizon Europe Missions

Moon-shot missions, such as those of Horizon Europe, require exceptional solutions, and the world-leading Analytical Research Infrastructures of Europe (ARIEs) are one of the key places those solutions can be sought. The ARIE Joint Position Paper highlighting how the common, complementary approach will help address the societal challenges of the Horizon Europe Missions framework programme was presented today.

Operando X-ray diffraction during laser 3D printing

Ultra-fast operando X-ray diffraction experiments reveal the temporal evolution of low and high temperature phases and the formation of residual stresses during laser 3D printing of a Ti-6Al-4V alloy. The profound influence of the length of the laser-scanning vector  on the evolving microstructure is revealed and elucidated.

Innovation Award on Synchrotron Radiation 2019 for the development of XFEL detectors using the adaptive gain principle

Innovation Award on Synchrotron Radiation 2019 for the development of XFEL detectors using the adaptive gain principle

The Innovation Award on Synchrotron Radiation 2019 was given to the researchers Prof. Heinz Graafsma from Desy and Dr. Aldo Mozzanica and Dr. Bernd Schmitt both from the Paul Scherrer Institute. The three physicists were honored for their contributions to the development of detectors for XFEL applications based on the dynamic gain switching principle enabling simultaneously single photon resolution and a large dynamic range. The laudation was held by Prof. Edgar Weckert from Desy. The Synchrotron Radiation Innovation Award is sponsored by SPECS GmbH and BESTEC GmbH.

Ultrafast diffuse x-ray scattering of a hybrid perovskite crystal

Organic–inorganic ‘hybrid’ perovskites have recently gained attention as a low-cost alternative to silicon solar cells. However, many properties of these materials are still poorly understood. In particular, how imperfections in the crystals, which can be both static or dynamic, affect energy transport remains unclear.

ExPaNDS partners meet at the grant kick-off meeting in September 2019

New 6M€ European grant awarded to ExPaNDS to drive open access data

A new 6M€ grant is being launched for the Photon and Neutron Data Services (ExPaNDS) to come together and work under the European Open Science Cloud (EOSC). This ambitious project will create enormous opportunities for scientific communities, and through their findings for humankind worldwide. It aims to publish and map the data behind the thousands of successful published scientific papers generated by Europe’s Photon and Neutron Research Infrastructures (PaN RIs) – which every year create petabytes of data – and make it available to all.

PSI School for Masterstudents 2019

PSI School for Master Degree Students - Introducing Photons, Neutrons and Muons for Condensed Matter Physics and Materials Science

From 17 – 21 June 2019 the Neutron and Muon Division (NUM) and the Photon Science Division (PSD) of PSI hosted 18 Master Degree students of physics, chemistry, materials and interdisciplinary science, as well as nuclear engineering to provide an introduction to the characterization of materials with large scale facilities like SINQ, SμS, SLS and SwissFEL. The course taught a basic understanding of how photons, neutrons and muons interact with matter, and how this knowledge can be used to solve specific problems in materials research.

First serial femtosecond crystallography experiment using SwissFEL’s large bandwidth X-ray pulses

The typical mode of operation at XFEL facilities uses the so-called self-amplified spontaneous emission (SASE) process to generate the short, bright X-ray pulses. This mode of operation is stochastic in nature, causing some variance in intensity and spectrum on a shot-to-shot basis, which makes certain types of crystallographic measurements much more challenging.
