Today, DT comprises about above 87 active staff, 59 fellows and students fully or partially funded by DT, and hosts 2 field support units (FSU S302 and S287).
DT staff is grouped in 7 sections: Technology and Physics (DT-TP), Detector Development (DT-DD), Fluidic Systems (DT-FS), Detector Interface (DT-DI), Engineering Office (DT-EO), Engineering Facilities (DT-EF), Detector Construction and Operations (DT-CO).
Work is however carried out in project or service teams often formed for a limited time with people from several sections and led by a DT project leader.
