Ion chamber gas
WebIon chambers are rarely operated in pulse mode, and this mode of operation is only considered for high- dE / dx particles that can deposit large amounts of energy in the gas. The main problem is the small size of the voltage pulse that is produced by the interaction of a single quantum of radiation. Web8 apr. 2024 · The impact of the so-called common-mode effect and of the ion tail on the signal shapes in the upgraded ALICE Time Projection Chamber with gas-electron multiplier readout are investigated. These two effects lead to significant baseline fluctuations, degrading the particle identification and tracking performance, as well as to baseline bias …
