The Compressed Baryonic Matter (CBM) experiment at the future Facility for
Antiproton and Ion Research (FAIR) aims to study the properties of nuclear
matter at high net-baryon densities and moderate temperatures.
The Silicon Tracking System (STS) is the key detector to reconstruct with
a high efficiency up to 1000 charged particle trajectories created in heavy-ion
collisions at interaction rates of up to 10 MHz. It will determine the momentum
of the particles with a momentum resolution ∆p/p ≈ 1-2% which requires ultralow
detector material budget of 0.3-1% X0 per layer. The detector comprise eight
layers of double-sided silicon microstrip sensors and will be placed inside the 1 Tm superconducting magnet which limits the space available, which in turn requires advanced cooling approaches and mechanical design with precise tracking layers alignment. The microstrip sensors have to be radiation hard and checked for their quality optically and electrically before the assembly.
This presentation summarizes the status of developments for the CBM STS
as well as for the detector demonstrator in a framework of mCBM campaign at
