Mainly during 2021 and 2022 and in the framework of the #CHIMERA (CHARM High-energy Ions for Micro Electronics Reliability Assurance) activity, with the financial and technical support from the European Space Agency - ESA, CERN developed its capacity for high-energy #heavyion testing of #electronics. This capacity is especially important for microelectronics components and assemblies that cannot be tested at #cyclotron facilities, due to the too shallow ion ranges and/or requirement of testing in vacuum. The results of this activity are summarized in our team's #RADECS2023 contribution, recently published as #OpenAccess in #IEEETNS: https://lnkd.in/e87Qi7YC. Since January 2023, the high-energy heavy ion beam and irradiation service development efforts at CERN are part of the EU-funded HEARTS project: https://hearts-project.eu/. Stay tunned for further results and achievements!

QuNET INITIATIVE DURING VISIT OF GERMAN FEDERAL PRESIDENT The #QuNET initiative, a research initiative funded by the Bundesministerium für Bildung und Forschung (Federal Ministry of Education and Research), is developing the foundations for highly secure #quantumcommunication systems using state-of-the-art #quantumtechnology. The systems for practically tap-proof #communication can, thus, pave the way for long-term data security and technological sovereignty. During the Federal President's visit to Fraunhofer IOF last week, QuNET researchers presented a model for quantum key distribution (#QKD). It demonstrated the exchange of quantum keys between a satellite and two ground stations. Such a system could one day form the basis of a global quantum network. Frank-Walter Steinmeier was able to experience the exhibit and the research behind it hands-on and observed how interference signals can be detected by changing the quantum states. The Fraunhofer IOF is also researching the future of communication using quanta as part of other projects, such as #HYPERSPACE, underlining the importance of #quantum research in the field of global communication systems. 👉 https://lnkd.in/ei3JWXYm Fraunhofer Heinrich Hertz Institute HHI, Deutsches Zentrum für Luft-und Raumfahrt e.V., FAU Erlangen-Nürnberg, Max Planck Institut für die Physik des Lichts Fabian Steinlechner, Karin Burger, Markus Leipe

Dr. Paul Quayle discusses the intricacies of space electronics at today's AFRL Regional Network - Midwest Annual Meeting. Here are 3 key takeaways: 1. Diamond emerges as a top contender for SWAP, and is predicted to be more resilient against solar and interstellar radiation. 2. GLCT, along with our AFRL collaborators, is at the forefront of advancing diamond electronics technology. 3. The AFRL network's strength lies in its capacity to foster and amplify relationships and collaboration across industry sectors, universities, and service branches. GLCT Team is excited about the future possibilities and advancements in space electronics!

Chromacity 1280nm ultrafast laser demonstrates effectiveness in US Government lab. Chromacity Ltd, a world leader in the design and development of ultrafast femtosecond and picosecond infra-red lasers, has been cited on new research done by Sandia National Laboratories, Albuquerque, USA. Sandia National Laboratories is one of the pre-eminent US Government labs, with a mission to undertake research focused on US national security, energy and nuclear. This research was focused on simulating the effectiveness of new semiconductor devices for radiation hardened applications. Sandia used the Chromacity 1280 ultra-fast laser as part of their system to simulate radiation-induced events in logic circuits. High energy particles are known to induce permanent or transitory effects in semiconductor devices. The recent outage in the NASA Voyager 1 spacecraft, where its memory was damaged was likely caused by a high energy particle strike. Semiconductor devices are becoming more vulnerable to damage caused by high energy particles. Electronics in space have always been vulnerable, with engineers developing an array of countermeasures to mitigate the issues caused by these high energy events. Semiconductor devices are rapidly adopting process technologies with smaller feature sizes, exacerbating the problem and potentially opening up the possibility of damage in devices used in terrestrial applications. The Chromacity 1280 has a 1280nm centre wavelength and is able to deliver sub 250fs pulses at a 100MHz repetition rate. It is part of a family of fixed wavelength femtosecond lasers, utilising Chromacity’s patented hybrid free space and fibre architecture, delivering class leading efficiency in a compact and robust form factor. More information about the research can be found here.  https://lnkd.in/emnNHN6m More information about the 1280 laser and other members of the family can be found here. https://lnkd.in/efmRehnq

My first peer-reviewed article resulting from one of my Master's projects has been published! The article is available in the link below and in the newest issue of IEEE Transactions on Nuclear Science. I would like to thank the co-authors and the reviewers for their guidance and feedback throughout this novel process. We present strategies for annealing of radiation damage in single-photon avalanche photodiodes via optical (laser) annealing. We investigate the influence of annealing duration and optical power on the diminishment of radiation-induced dark count rate. Moreover, we do this study in a vacuum environment, with the photodiodes and associated readout circuits integrated into a module suitable for cubesat power and mass limitations. The results of this study could aid in designing protocols for maintaining the operational characteristics of space-borne detectors, particularly for those intended for applications requiring ultra-low noise levels, such as quantum communication.

China’s ground-based timing system is part of its National Timing Service Center plan “for a system of systems approach” to #pnt . Its architecture has #satellite -based navigation at its heart and includes a wide variety of other capabilities." The country’s High-precision Ground-based Timing System will include “… more than 20,000 kilometers of optical fiber and 295 time and frequency transmission sites — and will integrate space- and ground-based signals.” The network will “supplement and improve the new #eLoran … system in the western portion of the country. It will also support legacy eLoran “long-wave” signals in the east ensuring that the entire nation is well served.” #china #pnt #apnt #gps #geospatial #beidou https://lnkd.in/gpNcHhV7

Crucial to the accuracy of an atomic clock is the width of the resonance used. Current caesium atomic clocks already use a very narrow resonance; strontium atomic clocks achieve a higher accuracy with only one second in 15 billion years. Further improvement is practically impossible to achieve with this method of electron excitation. Therefore, teams around the world have been working for several years on the concept of a “nuclear” clock, which uses transitions in the atomic nucleus as the pulse generator rather than in the atomic shell. Nuclear resonances are much more acute than the resonances of electrons in the atomic shell, but also much harder to excite. Atomic clocks have numerous applications that benefit from improved accuracy, such as precise positioning using satellite navigation. #nanotechnology #physics #science #satellite #GPS #GNSS #PNT #Timing #Technology #synchronization #iot #AtomicClocks #FrequencyStandards

🚀 Excited to share the submission of our new conference paper as part of ANTERRA: Antenna Systems Experts for 6G Non-Terrestrial Networks intitled "Soft Handover Strategy in Low Earth Orbit Satellite Networks; how strong the inter-satellite link should be" conducted in collaboration with Alberto Tarable,Alessandro Nordio, and Behrooz Makki 🛰️ Our paper focuses on the advantages of employing soft handover techniques, particularly in the uplink. We establish a realistic model for both ground-to-satellite and inter-satellite links. Key highlights of our findings include: 1- Quantification of the loss incurred by hard handover compared to soft handover through comprehensive simulations. 2- Evaluation of amplify-and-forward (AF) and decode-and-forward (DF) relaying techniques during handover, with a particular emphasis on block error rate (BLER). 3- Exploration of the impact of LEO constellation size on network BLER. 4- Revelation of the impact of misalignment on inter-satellite links, especially at optical frequencies, under soft handover scenarios. Our research sheds light on the crucial role soft handover plays in enhancing the performance and reliability of LEO satellite networks, offering valuable insights for future developments in the field.
