Simulation of the material budget of the CBM-MVD for the SIS-100* — •Tobias Tischler, Samir Amar-Youcef, Michael Deveaux, Michal Koziel, Christian Müntz, Christoph Schrader, and Joachim Stroth — Goethe Universität, Frankfurt

For the reconstruction of Open Charm Hadrons with the CBM experiment a Micro Vertex Detector (MVD) with an excellent resolution of the secondary decay vertex (<70 µm along the beam axis) is required. To achieve this vertex resolution a material budget of a few 0.1% X₀ is mandatory for the individual detector stations positioned downstream in close vicinity to the target. To further reduce the multiple scattering the MVD operates in vacuum.

We present a design study of the MVD for SIS-100 and its implementation into the CBM simulation package CbmRoot. Based on that a realistic estimation of the material budget of the SIS-100 MVD will be presented and discussed.
