  1. 36. VCSEL Reliability Studies and Development of Robust VCSEL Arrays
    Dr Anthony Weidberg (Nuclear Physics Laboratory)

    Opto
    Oral
    Severe problems with VCSEL reliability have been observed in ATLAS operation. ATLAS has developed the use of Optical Spectrum Analysers as a sensitive indication of VCSEL damage. These studies and detailed microscopic investigations have shown that the observed VCSEL reliability issues have been caused by moderate levels of humidity combined with the use of non-hermetic packages. Long term...

  2. 31. The radiation induced attenuation of specific single-mode and multi-mode optical fibres below -20°C exposed to full HL-LHC doses at a dose rate of 1 kGy/hr
    Mr David Hall (University of Oxford)

    Oral
    The Versatile Link (VL) project is developing a high-speed optical link for the HL-LHC. 850 nm VCSELs are more radiation-hard than 1310 nm EELs. Previous tests on multimode fibres at -25°C at 27 kGy/hr showed unacceptable radiation induced absorption. We have developed a CO2 cooling system which will be used in late June to irradiate cold fibres at low dose rates (1 kGy/hr) to the full HL-LHC...

  3. 151. First test results with the Gigabit Link Interface Board (GLIB)
    Dr Paschalis Vichoudis (CERN)
    29/09/2011, 11:50
    Opto
    Oral
    We have designed and built an FPGA-based platform for users of high speed optical links in high energy physics experiments. The Gigabit Link Interface Board (GLIB) serves both as a platform for the evaluation of optical links in the laboratory as well as a triggering and/or data acquisition system in beam or irradiation tests of detector modules. The GLIB is a double width Advanced Mezzanine...

  4. 121. Versatile Transceiver Development Status
    Csaba Soos (CERN)
    29/09/2011, 12:15
    Opto
    Oral
    The Versatile Link common project is developing optical link architectures and components to be used for readout and control in future HL-LHC experiments. The on-detector opto-electronic module, the Versatile Transceiver (VTRx), is derived from an industry standard module type and is adapted through minimal customization to the requirements dictated by the HL-LHC-specific front-end...
