SBND detector geometry¶
Detector description files are stored in GDML format in the sbndcode/Geometry/gdml directory.
The file name is sbnd_<PATCHLEVEL>.gdml (<PATCHLEVEL> is reported in the namesake column of the table below).
The "standard" configuration of SBND geometry is contained in the sbnd_geometry_services configuration bundle, and in particular in the sbnd_geo_source, in sbndcode/Geometry/geometry_sbnd.fcl file. The name of the GDML file loaded by LArSoft geometry is printed on the console when the Geometry service is initialised or updated.
A "no wires" version is present for each regular one, which has no TPC wires. This special file is not processed by LArSoft geometry but is intended to be used for Geant4 simulation, where the presence of wires has been shown to strongly slow down the simulation for little physics gain.
Versions prior to 1.0 are not documented here.
