  1. 24. A 65-nm-CMOS-process-based 10-Gbps VCSEL driver
    Jingbo Ye (Southern Methodist University, Department of Physics)

    Oral
    A VCSEL driver has been designed and fabricated in a SMIC 65-nm CMOS process. The preliminary testing results show the ASIC can work at 10 Gbps without peaking or emphasis structures. Due to the thin gate oxide of the technology and large size transistors used in the design, the VCSEL driver is potential radiation tolerant. We will present the irradiation testing results in the conference. To...

    Oral
    We present several ASICs of optical data transmission for the ATLAS liquid argon calorimeter trigger upgrade. These ASICs include a two-channel serializer (LOCs2), a single-channel and a four-channel VCSEL driver (LOCld1 and LOCld4), each channel operating at 8 Gbps. The serializer ASIC implements a low-latency, low-overhead, quick-resynchronization interface chip (LOCic) between ADCs and...

  3. 3. Single Event Upset Studies Using the ATLAS SCT
    Anthony Weidberg (University of Oxford (GB))
    26/09/2013, 11:10
    Oral
    Single Event Upsets (SEU) are expected to occur during high luminosity running of the ATLAS SemiConductor Tracker (SCT). The SEU cross sections were measured in pion beams with momenta in the range 200 to 465 MeV/c and proton test beams at 24 GeV/c but the extrapolation to LHC conditions is non-trivial because of the range of particle types and momenta. The SEUs studied occur in the p-i-n...

  4. 190. Gamma Irradiation of Minimal Latency Hollow-Core Photonic Bandgap Fibres
    Lauri Juhani Olantera (CERN)
    26/09/2013, 11:35
    Oral
    Hollow-core photonic-bandgap fibres (HC-PBGFs) offer many advantages over conventional fibres, such as low latency and radiation hardness; properties that make HC-PBGFs interesting for the HEP community. This contribution presents the results of gamma irradiation tests carried out using a new type of HC-PBGFs that combines low enough attenuation over distances that are reasonable for HEP...

  5. 193. System-level Testing of the Versatile Link Components
    Csaba Soos (CERN)
    26/09/2013, 12:00
    Oral
    During the first upgrade phase of the Large Hadron Collider experiments, high-speed optical links will be deployed to achieve the bandwidth needed to exploit the increasing luminosity and to allow data acquisition at higher rates. The Versatile Transceiver (VTRx) and Versatile Twin Transmitter (VTTx) modules are in their final development phase before production. They support different link...
