  1. 1. Fast Digital Trigger Systems for Experiments in High Energy Physics

    Författare :Pawel Marciniewski; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; trigger; discrimination; data acquisition; Fysik; Physics; Fysik;

    Sammanfattning : The data acquisition in high energy physics experiments is typically started by a pulse from a fast coincidence-based trigger system. It is essential that such a system can identify an event in a shortest possible time and with as good selectivity as possible. LÄS MER

  3. 2. Developments for the FPGA-Based Digitiser in the PANDA Electromagnetic Calorimeters

    Författare :Markus Preston; Per-Erik Tegnér; Samuel Silverstein; Pawel Marciniewski; Allan Hallgren; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PANDA; calorimeter; FPGA; single event upset; Geant4; Monte Carlo; pile-up; feature extraction; fysik; Physics;

    Sammanfattning : The strong interaction between quarks and gluons is one of the fundamental interactions described by the standard model of particle physics. Systems of quarks bound together by the strong interaction are known as hadrons, of which the proton and the neutron are the most common examples. LÄS MER

  4. 3. Single event upsets: measurements and modelling of proton- and neutron-induced errors in a 28 nm SRAM-based FPGA

    Författare :Markus Preston; Per-Erik Tegnér; Samuel Silverstein; Pawel Marciniewski; Andreas Heinz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Single event upset; FPGA; radiation damage; Monte Carlo simulation; PANDA; fysik; Physics;

    Sammanfattning : Single event upsets are radiation-induced errors affecting electronic devices, which can cause corruption of processed data. The electromagnetic calorimeter of the PANDA experiment — a hadron-physics experiment currently under development — will employ Xilinx Kintex-7 field-programmable gate arrays (FPGAs) in its readout electronics.

  5. 4. Time-Based Reconstruction of Hyperons at PANDA at FAIR

    Författare :Jenny Regina; Karin Schönning; Michael Papenbrock; Pawel Marciniewski; Sophie Grape; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PANDA; FAIR; hyperons; track reconstruction; online; cellular automaton; 4D tracking; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

    Sammanfattning : The PANDA (anti-Proton ANnihilation at DArmstadt) experiment at the future FAIR (Facility for Anti-proton and Ion Research) offers unique possibilities for performing hyperon physics.The almost full 4π coverage of the detector will enable the reconstruction of both hyperon and antihyperon which will be created together in proton-antiproton collisions.

  7. 5. Time for Hyperons : Development of Software Tools for Reconstructing Hyperons at PANDA and HADES

    Författare :Jenny Regina; Karin Schönning; Michael Papenbrock; Pawel Marciniewski; Laura Fabbietti; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Hyperon; Track reconstruction; 4D tracking; Free-streaming data; Kinematic fitting; PANDA; HADES; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

    Sammanfattning : The PANDA experiment at FAIR offers unique possibilities for performing hyperon physics. The detector will enable the reconstruction of both hyperon and antihyperon, which will be created together in proton-antiproton collisions. This enables investigations of the strong interaction in the non-perturbative regime. LÄS MER
