Dr. Rubén García Alía is part of the “Radiation to Electronics” (R2E) project at the European Organization for Nuclear Research, known as CERN, which he has led since 2018. After studying nuclear and high-energy physics at the Complutense University in Madrid (Spain), he started his career in radiation effects as a Young Graduate Trainee at the European Space Agency, in the Netherlands. From there, he completed his PhD with CERN and the University of Montpellier, focusing on the effect of highly energetic particles on Single Event Effects (SEE) in the Large Hadron Collider (LHC) accelerator. During this period, he was recognized with the “Best Student Paper” award at the 2012 Radiation Effects on Components and Systems (RADECS) Conference and the IEEE NPSS Paul Phelps Continuing Education Grant in 2015. Since then, he has kept a strong involvement in radiation effects research, focusing on high-energy accelerator applications, and has co-authored more than 100 publications in peer-reviewed journals. He has co-authored a RADECS Short Course, has been session chair at the Nuclear and Space Radiation Effects (NSRE) and RADECS Conferences, and was the technical chair for RADECS 2021. In 2020 he was elected as a Member-at-Large of the IEEE NPSS Radiation Effects Steering Group (RESG). He also received the NSREC 2022 Meritorious Paper Award for his work on high-energy ion fragmentation for SEE testing.

At CERN, Rubén’s main task is managing the R2E project, which is responsible for all radiation effects in the LHC accelerator and its injector chain, with the mandate of ensuring successful operation with regards to stochastic failures and lifetime degradation induced by radiation. The project, which is composed of more than 50 members, embeds a rich variety of activities and expertise, ranging from the monitoring and calculation of radiation levels, the operation and upgrade of CERN radiation facilities, and testing for radiation effects at both component and system level.

Between 2017 and 2022, Rubén coordinated the RADSAGA (RADiation and reliability challenges for electronics used in Space, Aviation, Ground and Accelerators), an innovative training Marie Curie PhD network. Currently, he is leading the RADiation facility Network for the EXploration of effects for indusTry and research (RADNEXT) and High-Energy Accelerators for Radiation Testing and Shielding (HEARTS) European Union projects, the first related to a network of European irradiation facilities and the second focusing on the development of European capabilities for high-energy heavy ion testing.

For contributions to the understanding of radiation effects on solid-state image sensors, particularly the origins of radiation-induced dark current random telegraph signals.

Biography

Cédric Virmontois is a detection chain and radiation expert at Centre National d’Études Spatiales (CNES) in Toulouse. He received the Engineering degree in Physics from the Institut National des Sciences Appliquées (INSA) of Toulouse in 2008 and the Ph.D. degree in Microelectronic and radiation effects from the Institut Supérieur de l’Aéronautique et de l’Espace (ISAE Supaero) of Toulouse in 2012. His Ph.D. research focused on displacement damage-induced degradation effects in CMOS image sensors. Since receiving his Ph.D. degree, Cédric has been working on radiation effects on solid-state image sensors and optoelectronic devices. First, he has focused on radiation effects on CMOS Image Sensor (CIS), especially on radiation induced dark current. Cedric has also contributed to the understanding and modeling of dark-current Random Telegraph Signals (RTS) in CIS. He contributed to the discovery of total ionizing dose-induced RTS in silicon-based image sensors. Then, Cédric has extended his radiation effects knowledge to other solid-state imaging technologies and focused on dark current RTS similarities in CIS and CCD devices (silicon-based sensors). He was the first to highlight the RTS discrepancies between silicon, mercury cadmium telluride (HgCdTe), and indium gallium arsenic (InGaAs) image sensors.

At CNES, Cédric focused his work for more than five years on radiation effects in the most recent generation of pinned photodiode CIS to make it possible to use this advanced technology in space. Today, this technology is exploited in numerous space imaging missions and is used especially in the SuperCam imager developed by Cedric, which is employed on the Perseverance MARS2020 NASA Rover. Today, Cedric directs the development of 4 imaging instruments based on this advanced technology.

Cédric has published over 40 articles in peer-reviewed journals and is a Senior Member of IEEE. He has served in many roles at the IEEE Nuclear and Space Radiation Effects Conference and Radiation Effects on Components and Systems Conference, as Short Course speaker, Session Chair Photonic Devices and ICs and member of the best technical award committee. For the past 10 years he has been a technical paper reviewer. Since 2012, Cédric was General Chairman of the annual Radiation Effects on Optoelectronic Detectors Workshop and Co-Chairman of the Space and Scientific CMOS Image Sensor Workshop organized by CNES.

His honors include four best conference paper awards, five outstanding student paper awards, and the IEEE Paul Phelps Continuing Education Grant for recognition of contributions to the fields of nuclear and plasma.
