The contribution of cables to the material budget of the CBM-MVD — •Philipp Klaus, Jan Michel, and Joachim Stroth for the CBM-MVD collaboration — Goethe-Universität Frankfurt

The Micro-Vertex Detector (MVD) for the CBM experiment will be used for a very high vertexing resolution. Making the destinction between primary and secondary vertices is crucial to finding rare and quickly decaying particles such as D-mesons.

For three out of four stations, the electrical connections have to placed inside the acceptance of the detector. Those cables make up about 1/3 of the total material budget. This contribution will describe the progress of reducing the material of the MVD detector stations by using Aluminium traces instead of Copper traces for the flat readout cables. The effect of the resulting lower material budget on the physics performance of the detector is being evaluated with simulations and will be shown.
