Project summary

The unique research opportunities for studies of baryons under extreme compression will be provided by the future International Accelerator Facility for Beams of Ions and Antiprotons (FAIR) in Darmstadt, Germany [1]. The decision to build FAIR is approved by the Federal Government of Germany. The project is supported by several other European countries with Russia among them.

The core of the CBM experiment is its Silicon Tracking System (STS). The major task of STS is to restore particle tracks and decay vertices of massive short-lived particles containing a charm quark. These particles are considered to be the most promising probes of channels of special interest in an attempt to find traces of quark-gluon plasma and chiral symmetry restoration.

Half of the STS is to be composed of planes of very thin, down to 100 um, double-sided silicon strip detectors. Although similar systems are being built in CERN, DESY, BNL, etc. never before the technical challenge for CBM STS was so close to the very edge of current technologies. The STS material in energy range of FAIR should be as thin as possible in order to reduce multiple scattering that limits position resolution and thus is the major factor for the success of the CBM experiment. Only a device with the record-breaking extra low material budget and increased reliability can meet the requirements of the planned experiment. The project proposed is focused on the designing, manufacturing and testing of a prototype of a Silicon Strip Detector (SSD) section with ultra low material budget for the Silicon Tracking System of CBM detector and based on cost-effective upgraded Russian technologies.
