Abstract
BackgroundThe Cylindrical Gas Electron Multiplier Inner Tracker (CGEM-IT) is one of the candidates for the replacement of the current BESIII inner drift chamber,which has developed serious aging effects due to beam-related backgrounds.
PurposeTo build a full digitization model,it is necessary to understand the electron drift behavior and signal induction.
MethodsA simulation study based on Garfield++and ANSYS software has been performed.
ResultsParameters describing the Lorentz angle,diffusion effect,drift time,multiplication,and induction are obtained from the Garfield++simulation.Based on these results,a preliminary digitization model is implemented in the BESIII offline software system.
