1. RPC Digitization Marcello Maggi/INFN-Bari Raffaello Trentadue/INFN and Dip. Bari

2. RPC Digis status (ORCA…) Recently ORCA digitizer was improved to describe the average behavior of the RPC in comparison with real performance as extracted in the cosmic stands (never committed, but used internally for the RPC group) RPC L1 Trigger emulation performance was then studied in detailed

3. New RPC Digitizer design MRpcEmulatorBasicAverageDetailed Digi() MRpcDigitizer Digi() Geometry Service MRpcGeoInterf Number of strip() StripLength() DeadArea() Performance Service Basic: orca like Average: default Detailed: chamber by chamber simul

4. Work in progress (CMSSW…) Lower Level DetUnit changed. Geometry xml files just released by Pawel, and beeing reviewed by Pedro. RPC Geometry classes and DetUnitId start being committed New Digitizer depends on this and it has been redesigned. Skeleton exists but has to be committed

5. Plans and Time Scale next week: Finalize Geometry Commit RPCDigitizer skeleton Near future: Implement the digitization Port the auxilary classes from ORCA
