  • As of global tag dddb-20150724 the Herschel geometry is included in the DDDB. This includes not only the scintillators themselves but also a (somewhat simplified) model of the vacuum chamber sections, magnets and absorbers up to B2 and F2.

    • extend the Geant4 tracking cuts to z= ± 125 m,
    • and include the algorithm MaskParticles in the generator sequence.
