Summary • GSI detector laboratory will face many exciting challenges during the research and construction phase of FAIR till 2015 • There will be an essential need for on-site silicon integration facilities as well as know-how. GSI detector lab will respond and strives to be understood also as the local contact for final integration and commissioning of FAIR detector systems. • Silicon system integration will be the strategically novel orientation. • It will be backed with a considerable future investment in infrastructure and clean-room lab space at GSI. • The interwoven marriage of readout electronics and detector devices as with Silicon detectors will break grounds for much closer integration even for gas detectors.
