SummarySummary

International accelerator facility FAIR under preparation

Unprecedented and new research opportunities in various fields for large scientific communities

Silicon detector systems will be important

Challenging

some because small research groups go into new detector dimensions

some because truly demanding devices are required

very high channel densities high radiation environment very fast readout very low mass pretty big ( CBM)

Cooperations of the GSIFAIR groups eg on Sensors FEE labs

Inputadvice from other experienced communities searched for

One example Planned are in-kind contributions from Finland to FAIR with rad-hard silicon strip detectors (incl RD39-RD50
