TileCal description in GeoModel

Package structure

TileCal detector description consists of two main packages:

• TileCalorimeter/TileGeoModel - contains GeoModel specific classes such as detector tool and two factories for building geometries of the entire tile calorimeter and also tile part of the combined testbeam setup.
• TileCalorimeter/TileDetDescr - contains the Tile Detector Description Manager and also classes which retrieve tile detector description primary numbers from two different sources: Atlas Geometry DB and NOVA (obsolete).

Geometry layouts

It is possible to build the following geometry layouts for TileCal

• TileCal-00 (entire calorimeter). This is the complete geometry of TileCal which was used in DC2 and Rome productions (both Rome-Initial and Rome-Final).
  
  
• TileCal-01 (entire calorimeter). The only difference between this layout and TileCal-00 is that in TileCal-01 the gap scintillator layers are not built. This layout was supposed to go in the Rome-Initial layout of ATLAS detector, but then it was decided not to use it at all. So TileCal-01 is considered to be an obsolete layout. To explicitly build this geometry one needs to put the following overriders in the job options script:
  GeoModelSvc.TileVersionOverride = "TileCal-01"
  
  
• CTB. Builds the tilecal part of combined testbeam setup geometry. This layout consists of 3 central barrel modules (with so called fingers) and 3 extended barrel modules. To build tile CTB layout one needs to set
  GeoModelSvc.TileDetectorTool.TestBeam = TRUE
