Physics experiments use time to measure physical quantities or to apply selection conditions. The required precision is driven by each specific case. Tens of picoseconds for minimum ionizing particle is what the future physics at the HL-LHC is requiring in time precision for pile-up and background subtraction. In some circumstances, high precision timing has to coexist with high rates and high...
At the future International Linear Collider (ILC) project a GEM- or Micromegas-based Time Projection Chamber (TPC) is a candidate for the central tracker of the International Large Detector (ILD), which is one of the two detector concepts proposed for the ILC.
The TPC has a potential problem that many ions generated in avalanche processes for gas amplification flow back into the drift...
