DESCRIPTION OF THE WORK PACKAGE

The project aims to cover strategic R&D towards the development of large-volume drift chambers proposed as tracking and particle identification devices for the next generation of lepton colliders both at FCC-ee (CERN) and at CEPC (IHEP China). Analogous proposals exist for the next generation of flavor factories SCTF (Russia, China) and could easily be adapted for Electron-Ion Colliders. Drift chambers provide high-precision tracking even at low transverse momentum thanks to the high transparency, and excellent particle identification by profiting from the cluster counting information. Key aspects for the R&D challenges are related to the mechanics, the electronics and the choice of gas mixture.
