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 mid Aoril April 2009, the validation geometry and materials used by the Radiation Trask Force have been implemented in Geant4. We have checked for and removed volume overlaps. We have run FLUGG. The next step is to define the outputs necessary for comparison with the Task Force results.
Work has started on the 2009 start-up geometry.
Meetings and Material
The cavern background group meets at 17:30 (CERN) biweekly on Thursday. Agendas can be found at http://indico.cern.ch/categoryDisplay.py?categId=225
