Abstract / Description:The aim of this note is to describe the Muon Digitization software packages, completely re-written to run in the ATHENA framework and to interface with the GEANT4 Muon Spectrometer simulation. The Muon Digitization is the simulation of the Raw Data Objects (RDO), or the electronic output, of the Muon Spectrometer. In the present architecture, it consists of two steps: in the first step, the output of the detector simulation, the Muon Hits, is converted to Muon Digits, i.e., intermediate objects that can be fed into the reconstruction. In the second step, the Muon Digits are converted into RDO, the transient representation of raw the data byte stream. In this paper we will describe the detailed implementation of the first step of the Muon Digitization, where the detector simulation output is digitized into Muon Digits, also referred as Reconstruction Input Objects (RIO). This procedure occurs separately for each Muon technology. The second step, which convert the RIO in the RDO (byte stream) is implemented in separate algorithms. We will describe the fundamentals of the Muon Digitization algorithms, outlining the global structure of them, with some emphasis on the simulation of piled-up events, on the link to the Monte Carlo Truth and on the Digitization validation against the Monte Carlo information.
