High tech particle accelerators are vital machines made of superconducting radiofrequency (SRF) cavities which accelerate charged particles for high-speed and high-energy particle collisions result in immense data to be analyzed in order to answer such aforementioned fundamental questions. The R&D in materials used for SRF cavities is essential step to develop such systems further. Dr. Antoine, C. Z., who works at CEA-Irfu /University of Paris-Saclay and having more than thirty years of experience in surface and material studies for SRF cavities, is going to give a talk on: “Superconducting RF cavities for accelerators: material and surface issues” highlighting the details of technological bottlenecks to be targeted in order to develop SRF cavity com-ponents of particle accelerators.
