  1. 30. Architecture of a Level 1 Track Trigger for the CMS Experiment
    Prof. Ulrich Heintz (Brown University), Ulrich Heintz (Unknown)

    High speed communication
    Oral presentation
    The luminosity goal for the Super-LHC is 10^35/cm^2/s. At this luminosity the number of proton-proton interactions in each beam crossing will be in the hundreds. This will stress many components of the CMS detector. One system that has to be upgraded is the trigger system. To keep the rate at which the level 1 trigger fires manageable, information from the tracker has to be integrated into the...

  2. 12. FF-LYNX: protocol and interfaces for the control and readout of future silicon detectors

    High speed communication
    Oral presentation
    Future High Energy Physics experiments will have similar requirements with respect to latency, bandwidth, robustness against transmission errors and component failures, radiation hardness and power dissipation of hardware components. The FF-LYNX project started from the assumption that a general purpose flexible protocol implemented in IP cores available to future ASIC designers can fit these...

  3. 11. Wireless data transfer at 60 GHz
    Dr Richard Brenner (University of Uppsala)

    High speed communication
    Oral presentation
    The data transfer rate from highly granular tracking detectors are today limited by the available bandwidth in the readout links. This prevents the detectors from being used for fast triggering. To get the tracker to contribute to a fast trigger decision the data rate from the tracker has to be increased or the quantity of data to decrease. A higher data transfer rate can be achieved by...

  4. 7. New Optical Technology for Low Mass Intelligent Trigger and Readout
    David Underwood (Argonne National Laboratory (ANL))

    High speed communication
    Oral presentation
    We describe a number of new electro-optical technologies which would enable data transmission with very low mass and power. Extremely small optical modulators which can be integrated into CMOS chips would allow the mass and power of lasers to be displaced outside the tracking volume. These modulators could be used to pass data between tracking layers of order cm apart rather than mm, enabling...

  5. 25. Ultra low power consumption 10.7 Gb/s transmission over 2 km single mode fiber optics link
    Dr Davide Janner (ICFO-The Institute of Photonic Sciences, Barcelona, Spain)

    High speed communication
    Oral presentation
    In this work we demonstrate a digital error-free transmission (BER < 1e-12) at a bit rate of 10.7 Gb/s over a 2 km optical-link obtained with an ultra-low-voltage lithium niobate Mach-Zehnder modulator (LNM) driven by 0.6 Vpp and with 1 mW of optical input power at a wavelength of 1550 nm. Voltages in this range allow driving the modulator directly from the board and placing the optical active...
