The document summarizes the geometry, hit/digit creation process, and additional noise sources being simulated in the Tracker MC software. It describes the placement of scintillating fibers within the tracker stations and the conversion of energy deposits into potential photoelectrons and digital signals. Thermal excitation of VLPCs and X-ray excitation from RF cavities are also modeled as additional noise sources. The simulation aims to accurately model the full data acquisition process in the tracker from particle interactions to output signals.
