The love affair between CERN and UNamur goes back a long way. CERN's accelerator complex and experimental program are very different and much larger than those of UNamur's Physics Department, but the fields in which the two institutions work have much in common.

In addition, both guests have a personal history with UNamur. The Physics Department was pleased to welcome Serge Mathot, Referent Applied Physicist (CERN) and alumni of the UNamur Physics Department (1992), as well as François Briard, Group Leader Science Portal (CERN), and alumni of the UNamur Faculty of Computer Science (1994).

The activities began with a meeting between the guests, Rector Annick Castiaux, Vice-Rector for Research Carine Michiels, Physics Department Director Pierre Louette and several other members of the Physics and Biology Department. After a general presentation of the University, the participants pointed out the missions shared by both institutions: research and the transfer of technology and knowledge, service to society, scientific popularization and education and training.

Physics lunch - CERN presentation

The physics lunch is the monthly meeting between students and members of the physics department and a professional, alumni or not, coming to explain his or her background and what he or she does on a daily basis as a physicist.

During this meeting, attended by around 80 people, François Briard and Serge Mathot presented CERN, the world's largest laboratory for particle physics. CERN's mission is to understand the most elementary particles and the laws of our universe.

At the end of the seminar, the students came away with stars in their eyes. Indeed, opportunities for internships or even first jobs at CERN are possible for physicists but also in many other fields.

Some internship programs at CERN are particularly well suited to the needs of young Belgian students.

The vast majority of physicists working with CERN (over 13,000) are in fact sent to CERN for varying periods of time by their employing national research institutes. CERN offers an exceptional opportunity to develop international experience under excellent conditions, in an environment that is unique in the world! What an inspiration for our young students!

The projet d'Action Recherche Concertée (ARC) PHOENIX aims to renew our understanding of medieval parchments and ancient coins. Artificial intelligence will be exploited to analyze the data generated by material characterization.

This joint study between the Department of Physics and the Namur Institute of Structured Matter (NISM) and the Department of History and the Institut Patrimoines, Transmissions, Héritages (PaTHs) will address questions relating to the production chain and use of these objects and materials in past societies.

At the same time, Serge Mathot presented a seminar in heritage science attended by some 50 people. In particular, he presented his research and the brand-new ELISA accelerator: a miniaturized gas pedal capable of delivering a 2 MeV proton beam used to perform real measurements at the Science Portal.

Having the opportunity to exchange views with François Briard, Group Leader of the CERN Science Portal is a rare opportunity. Comparing outreach activities has opened up new avenues, discovering and sharing approaches, assessing what works and what doesn't, depending on the target audience. A highly satisfying enrichment for the members present from Confluent des Savoirs (CDS), the University of Namur's research outreach and dissemination service.

Professor Anne-Catherine Heuskin and Dr. Boris Hespeels are currently working on the BEBLOB project, a Belspo project with ESA support, as part of the UNIVERSEH (European Space University for Earth and Humanity) alliance. They are particularly interested in its astonishing ability to withstand high doses of radiation.

Anne-Catherine Heuskin also works in radiobiology. Particles are used to irradiate cancerous cells in order to destroy their genetic material and prevent them from proliferating: this is the basis of radiotherapy and proton therapy.

The meeting confirmed the willingness of FaSEF and UNamur to get involved in coordinating the Belgian National Teacher Programme in French-speaking Belgium, which CERN intends to relaunch in 2026. Consideration was also given to other avenues for teacher training, such as CERN's forthcoming involvement in the "Salle des Pros", the training venue for the various players involved in teacher training at UNamur.

The TRAKK is Namur's creative hub supported by 3 complementary partners in the field: BEP, KIKK, and UNamur. In addition to the venue, François Briard was able to visit the ProtoLab , which bridges the gap between ideas and industry by being a decentralized research and development hub accessible to SMEs and project leaders by offering advanced support in prototyping products or services.

Graduating in law and information technology management (DGTIC) in 1994 after his bachelor's and master's degrees in computer science in 1993, François Briard works at CERN, the European Organization for Nuclear Research in Geneva, the world's largest particle physics laboratory.

During his school career, which was 100% at UNamur, he was vice-president of the Régionale namuroise and student delegate during his years as a candidate in economic and social sciences, computer science option.

Thanks to the multidisciplinary training provided at UNamur, he was able to seize several opportunities to redirect his career at CERN, where he was an information systems engineer from 1994 and then, from 2014, redirected his career until he became Group Leader of the Science Portal, which is CERN's general public communications center.

Serge Mathot obtained his doctorate in applied sciences from UNamur in 1992, following his bachelor's degree in physical sciences in 1985.

He then carried out a post-doctorate at the Joint Research Center (EU science hub) in Geel, which aims to bring together multidisciplinary skills to develop new measurement methods and tools such as reference materials.

He perfected his expertise in physical metallurgy before joining CERN in 1995 as a Referent Applied Physicist. He has worked on numerous research projects (CLOUD, MACHINA, ELISA...) and developed numerous parts for the manufacture of CERN's gas pedals.

CERN, the European Organization for Nuclear Research, is one of the world's largest and most prestigious scientific laboratories. Its vocation is fundamental physics, the discovery of the constituents and laws of the Universe. It uses highly complex scientific instruments to probe the ultimate constituents of matter: the fundamental particles. By studying what happens when these particles collide, physicists understand the laws of Nature.

The instruments used at CERN are particle gas pedals and detectors. Gas pedals carry beams of particles at high energies to collide with other beams or fixed targets. Detectors observe and record the results of these collisions.

Founded in 1954, CERN is located on either side of the French-Swiss border, near Geneva. It was one of the first organizations on a European scale and today has 25 member states, including Belgium.

This initiative is spearheaded by Fanny Martin, lecturer in national archaeology at UNamur. "Leaving archaeology studies without having experienced the discipline doesn't make much sense. When I arrived, the University of Namur didn't yet have any field schools. It seemed essential to me to offer a project for students, because field archaeology is a discipline in its own right," she explains. Julian Richard, professor of Greek and Roman archaeology and head of the department, adds: "At UNamur, our trump card is to take students out into the field as much as possible. Right from the bachelor's level, they are brought into contact with the object, observing it, manipulating it, understanding it. This is a pedagogy we're keen on, and setting up work-schools is part of it."

During these work-schools, students, confronted with the realities of the field, have to apply their theoretical knowledge to concrete situations, developing not only their technical skills, but also analytical and problem-solving abilities. "In the first and second years, students receive a methodological background on excavation. And then, between their second and third years, they go out on the training site for two weeks and put these principles into practice," adds Fanny Martin.

I got a lot out of this internship. The team on site was lovely. We first learned the basics of excavation, then, little by little, explored all the stages of the discipline, which was exciting", she recounts. Marion Drabbé, a third-year bachelor's student in archaeology, backs up Bérénice's words, adding, "I was a little apprehensive, as the workcamps are like a little exam in our curriculum. But in the end, it was a great experience. We were surrounded by lovely professionals, and I was supervised by Fanny Thirion, archaeologist at the Musée des Celtes. It was great! These workcamps let you see what you're studying, and you realize just how precise and meticulous archaeology is. There's also the satisfaction of discovering previously unseen objects: we found an urn with bone residues and a fibula pin, which is quite rare in excavations. We were delighted!".

The experience of workcamps is not just professional. For Bérénice Didier, it was also a time for sharing and cohesion: "It felt a bit like summer camp. It was really great and I had the opportunity to forge a lot of bonds." Outside digging hours, the students share their daily lives, which fosters strong bonds and develops their ability to work as a team.

These workcamps, which constitute research projects in their own right, require significant organization and varied support. "We chose to work in the Tintigny region, in Gaume. The site is in conservation danger, and we benefit from funding from the Agence wallonne du Patrimoine as well as a partnership with the Musée des Celtes de Libramont and the Commune de Tintigny to carry out the operations. This type of project requires a lot of collaboration to manage the logistics and the study," explains Fanny Martin. What's more, support from partners and UNamur means that internships are free of charge, so that no student is deprived of this opportunity.

These projects fulfill a dual societal mission: to preserve and pass on heritage to society. With this in mind, students welcome visitors to the site to share their discoveries, enabling them to acquire cultural mediation skills. Bérénice testifies: "Giving guided tours really appealed to me, to the point of making me want to explore this field in the future". Marion adds: "The tours were really enriching. You realize that being able to express your budding knowledge in front of people who are interested in what you're telling them is also very glorifying". This dimension makes these internships much more than mere digs: they are also places of transmission where students value their work to society.

The work sites are also a first experience in the professional world. "They offer them a first baggage for the future", notes Julian Richard. Students can also take part in international missions, such as those organized by Julian Richard in Ostia, the ancient port of Rome, with UCLouvain. These excavations abroad bring a complementary perspective and enrich their training through the study of other contexts, particularly built, as well as other periods.

Thanks to this approach, UNamur archaeology students develop a deeper understanding of their field while building a useful professional network for the future. The workcamp-school becomes a landmark experience, preparing students both academically and personally for the rest of their career.

Y avait-il déjà des vitres aux fenêtres au temps des Romains ? La réponse est oui ! Vertes, bleues, jaunes ou incolores, les vitres avaient des formes et des usages variés. La manière dont ce verre à vitre était produit à l'époque romaine continue cependant de faire débat entre les scientifiques. À l'UNamur, les archéologues tentent de percer les secrets de cette production, en partenariat avec des artisans verriers et Malagne, l’archéoparc de Rochefort. Cette expérience s'inscrit dans la thèse de doctorat menée à l’UNamur par Géraldine Frère, sous la direction du professeur Julian Richard.

Chercheuse doctorante, Géraldine Frère étudie depuis 2019 les productions et les usages du verre à vitre entre le 1er et le 5e siècle en Gaule Belgique et en Germanie inférieure, un vaste espace qui correspond à la Belgique actuelle, aux Pays-Bas, au Luxembourg et au nord de la France. Sa recherche est à l’origine du projet Specularia (de specularis, vitres ou fenêtres en latin). 

Expérimenter un processus jamais tenté

Le projet entend décrypter les pratiques des artisans romains en recréant deux fours à verre « à l’antique » au sein de l’archéoparc. Le premier sera utilisé pour la fusion du matériau, l’autre pour sa recuisson, deux étapes indispensables de la production du verre. L’expérience sera menée par Géraldine Frère avec l'aide d’artisans verriers (Allain Guillot et "Les infondus") qui utiliseront des techniques et des outils "à la romaine", spécialement conçus sur base d’expérimentations antérieures et des traces retrouvées sur les fragments de vitres antiques. Le verre sera mis en forme suivant un processus inédit et différent de tout ce qui a été testé jusqu’ici : le verre en fusion sera cueilli dans le four, déposé sur une surface avec un cadre chauffée préalablement, puis étiré à l'aide d'outils jusqu'à obtention d'une forme rectangulaire. 

Un objectif scientifique et pédagogique

Ce projet permettra aux étudiantes et aux étudiants du Département d’Histoire de l’Art et d’Archéologie de suivre un projet d’archéologie expérimentale en région namuroise. Le public pourra également voir la progression de l’expérience, de la construction des fours dans l’archéoparc au coulage des vitres, avec comme point d’orgue « le Rendez-vous gallo-romain » organisé les 15-16 juillet 2023. Les résultats des expériences seront valorisés scientifiquement dans le cadre du projet de recherche Specularia.  

Un financement participatif 

Pour mener cette expérience à bien, le Département d’archéologie est à la recherche de 10.000 euros. Cette somme sera intégralement utilisée pour acheter les matériaux permettant de construire les fours et couler le verre (bois, argile, sable, tuiles…) au sein de l'archéoparc et financer le travail des verriers durant la durée de l’expérience (mai-juillet 2023).

Specularia, c’est un projet mêlant innovation scientifique et artisanat dans le domaine de l’archéologie du verre plat. Son but : tester les théories émises depuis plus d’un siècle par les archéologues pour expliquer le processus de mise en forme des vitres à l’époque romaine, et vérifier leur faisabilité dans des conditions réelles (en lire plus ici).

Le projet est piloté par le professeur Julian Richard et Géraldine Frère, chercheuse doctorante et assistante au Département d’histoire de l’art et archéologie de l’UNamur.

Entre mai et juillet 2023, une équipe de scientifiques et d’artisans verriers recréera la chaine de production du verre à l’époque romaine, c’est-à-dire de la construction de fours jusqu’à la production de vitres selon les techniques romaines ou supposées telles.

Ce projet apportera des réponses concrètes aux questions posées de longue date dans le domaine de l’archéologie du verre et constituera une première en matière d’archéologie expérimentale au sein du Département d’histoire de l’art et archéologie de l’UNamur. L’expérience se tiendra dans le cadre exceptionnel de Malagne, l’archéoparc de Rochefort : ce site classé (voir photo ci-dessus) permettra d’insérer l’expérience au cœur d’un parcours pédagogique et mettra l’innovation scientifique à la portée du grand public et des écoles. Le coulage des vitres interviendra en particulier lors du « Week-end gallo-romain » organisé par Malagne les 15 et 16 juillet 2023.

Ce projet implique l’achat de fournitures peu habituelles pour des recherches en laboratoire : argile réfractaire, tuiles, sable de rivière… Pour rassembler les fonds nécessaires, l’UNamur a lancé un crowdfunding qui a progressé de manière significative depuis son lancement grâce au soutien du grand public et de passionnés d’archéologie, ou encore du Musée du Verre de la Ville de Charleroi.  C’est au tour d’AGC Glass Europede s’associer à ce projet.

Mettre en lumière l’innovation en recherche de manière attractive et originale, en dehors des murs de l’université, est également une perspective soutenue par AGC Glass Europe : « Contribuer aux activités culturelles et de médiation scientifique, notamment vis-à-vis des jeunes s’inscrit dans la mission d’entreprise citoyenne responsable AGCitizen. Par le soutien qu’elle apporte à ce type de projets, AGC Glass Europe contribue à l'éducation et au développement professionnel des jeunes », poursuit Niels Schreuder. L’expérience sera en effet valorisée au sein du parcours pédagogique proposé par Malagne, qui accueille 14.000 visiteurs par an, dont 9.300 élèves, mais également auprès des étudiantes et des étudiants du Département d’histoire de l’art et archéologie de l’UNamur.

L’UNamur remercie l’ensemble des partenaires et soutiens qui se sont déjà manifestés afin de faire de cette expérience une réalité. Il reste encore un mois pour participer à au financement participatif du projet Specularia. Aidez-nous à atteindre les 10.000 € !
