PROJECT INTERIM ACTIVITY REPORT FOR SEMESTER 4

The EuCARD project gathers 37 European partners engaged in state-of the-art technologies to upgrade major research accelerators. The main components and objectives of the project are: • Networks, focused on communication and dissemination, neutrino physics facilities, performance of hadron colliders and accelerators, and RF technologies, resulting in 40 leading laboratories worldwide being associated with EuCARD. • Transnational access facilities, offering precision beams and muon cooling setup, and pulsed irradiation for material testing. • Joint research: 21 R&D tasks grouped under the following themes: o Investigating the feasibility of new superconducting magnets and electrical links using Nb$_{3}$Sn and/or High Temperature Superconductors. o Investigating the gradient limits for radiofrequency (RF) accelerating structures, whether normal or superconducting, together with specific issues of linear colliders such as extreme geometrical stabilization. o Developing more robust collimators for the protection of accelerators in operational and exceptional conditions. o Supporting investigations on novel accelerator concepts, such as crab waist crossing, fixed field alternating gradient and plasma wave accelerators.
