Particle identification with the cluster counting technique for the IDEA drift chamber

IDEA (Innovative Detector for an Electron-positron Accelerator) is a general-purpose detector concept, designed to study electron-positron collisions in wide energy range from very large circular leptonic collider. Its drift chamber provide efficient tracking, high precision momentum measurement and excellent particle identification by exploiting the application of cluster counting technique. To investigate potential techniques on physics events, simulation ionization clusters generation needed, therefore we developed algorithm which can use deposit information provided Geant4 toolkit reproduce, fast convenient way, number distribution size distribution. The results obtained confirm that technique allows reach resolution 2 times better than traditional dE/dx method. A beam test has been performed during November 2021 at CERN H8 validate simulations results, define limiting effects fully count electron released ionizing track fixed $\beta\gamma$ as function angle. will be described briefly this issue.
