ATLAS will be replacing the Inner Detector tracker for Super LHC. It is expected to be an all-Silicon detector with pixels and strips. We believe additional shielding is needed for the FCAL. It is also expected to replace part of the muon spectrometer detectors. The scope of the muon upgrade has great uncertainty at this time. It can be as little as replacing the endcap detectors at small radii, or it can be replacing all muon detectors, depending on the background level. One of the goals of the cavern background calculation is to provide a more reliable prediction.
Status
As of May 2009February 2010, the validation against RBTF is complete, the start-up geometry and materials used by the Radiation Trask Force have been implemented. First results from FLUGG are available. The next step is to define the outputs necessary for comparison with the Task Force results.Work has started on the 2009 start-up geometryhas been implemented, and preliminary cavern background files have been written out. We are now working on using these background files in ATLAS simulation.
