• Outline
Simulation tools (cbmroot) & geometry
•SBM framework last edition (3 first Sts in vacuum);•"standard" and 700 m thickness STS geometry;•7 stations at 5, 10, 20, 40, 60, 80, 100 cm;• stations at 5 and10 cm - 100 m others 200 m•single Au target 500 m, = 10 m (double) hit displacement (Gaussian smearing) at CbmStsDoubleHitProducer.cxx•GEANT3, UrQmd (25 Gev) and D0 K-,+ (by V.Friese) generators;• no Magnetic Field, but dP/P = 1%
