Installation of the Belle II Central Drift Chamber completed

2016/10/21

On Oct. 13th 2016, the Central Drift Chamber (CDC) for the Belle II detector was successfully installed.

The CDC is a crucial sub-detector, as it provides the momentum of electrically-charged particles by reconstructing their curved trajectories while moving in a magnetic field. The information provided by the CDC is also a key ingredient of the Belle II trigger system. Additionally, the CDC contributes to particle identification by measuring the energy loss of charged particles as they pass through the gas that fills the CDC.
