Abstract [en]

The amount of data that can be transferred from highly granular tracking detectors with several million channels is today limited by the available bandwidth in the readout links which again is limited by power budget, mass and the available space for services. The low bandwidth prevents the tracker from being fully read out in real time which is a requirement for becomming a part of the first level trigger. To get the tracker to contribute to the fast trigger decision the data transfer bandwidth from the tracker has either to be increased for all data to be read out in real time or the quantity of the data to be reduced by improving the quality of the data or a combination of the two. A higher data transfer rate can be achieved by increasing the the number of data links, the data transfer speed or a combination of both. The quantity of data read out from the detector can be reduced by introducing on-detector intelligence. Next generation multigigabit wireless technology has several features that makes the technology attractive for use in future trackers. The technology can provide both higher bandwidth for data readout and means to build on-detector intelligence to improve the quality of data. The emerging millimetre wave technology offers components that are small size, low power and mass thus well suited for integration in trackers. In this paper the feasibility of wireless transfer of trigger data using 60GHz radio in the future upgraded tracker at the Super Large Hadron Collider (SLHC) is investigated.
