    Title: Design of a high power OOK modulator and verification of circuits in 60GHz SiGe BiCMOS
    Author: Ersdal, Magnus Rentsch
    Publisher: The University of Bergen
    Date: 2017-06-29
    Subject: Mastergrad ; 752199
    Description: In this thesis, components for the UiB 60 GHz system are verified numerically and an on-off-keying (OOK) modulator is designed. Presence of mass in particle detector systems decrease the accuracy measuring the particle paths. This is a problem e.g. in the ALICE and ATLAS experiments. The detector systems are also highly complex, and difficult to construct. For reducing the mass and the construction complexity of particle detector systems, wireless data transfer for the sensors is proposed by WADAPT. The Microelectronics group at the University of Bergen (UiB/UoB) is working on the development of a low-power 60 GHz transceiver chip for this purpose. A previous system design exists, suggested by H.K. Soltveit, using a heterodyne receiver. This thesis suggests that a small improvement of power consumption can be achieved with a homodyne receiver scheme A previously designed three-stage LNA for 60 GHz with ≥ 9 GHz bandwidth and ≤ 4.5 dB noise figure is verified and adjusted with...

    Description: Abstract One of the key challenges for nuclear physics today is to understand from first principles the effective interaction between hadrons with different quark content. First successes have been achieved using techniques that solve the dynamics of quarks and gluons on discrete space-time lattices 1,2 . Experimentally, the dynamics of the strong interaction have been studied by scattering hadrons off each other. Such scattering experiments are difficult or impossible for unstable hadrons 3–6 and so high-quality measurements exist only for hadrons containing up and down quarks 7 . Here we demonstrate that measuring correlations in the momentum space between hadron pairs 8–12 produced in ultrarelativistic proton–proton collisions at the CERN Large Hadron Collider (LHC) provides a precise method with which to obtain the missing information on the interaction dynamics between any pair of unstable hadrons. Specifically, we discuss the case of the interaction of baryons containing...
