EP-DT has a central and coordinating role in the development, construction and operation of particle detectors and related infrastructure for experiments at CERN. The group activities are organized in 3 main categories:

• Services for developing and operating infrastructures for experiments and detector R&D. They are available for all experiments at CERN. They offer a coherent, ready-to-use deliverable (e.g. gas system, cooling system, control system, B-field measurement, thin film coating), M&O support, advice and consultancy.
• R&D Projects on strategic fields related to new detector technologies and detector infrastructures that are of common interest for all the experiments. These projects also provide a host lab environment for external partners.
• Joint Projects with experimental teams in CERN experiments to develop, construct and operate particle detectors. Joint projects are set up for a defined amount of time and the scope of the collaboration is described in dedicated work package agreements.
