  3. 2. Detector Development, Source Characterization and Novel Applications of Laser Ion Acceleration

    Författare :Lovisa Senje; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Laser; Ion; Acceleration; Proton; Water; Sheath; Lifetime; Laser; Ion; Acceleration; Proton; Water; Radiolysis; Sheath; Detector; Fysicumarkivet A:2017:Senje;

    Sammanfattning : The main focus of the work presented in this thesis is on experimental studies oflaser acceleration of protons and other positive ions from solid targets. The topic is explored from three different angles: firstly, the development of diagnostics adapted to the ion pulses, secondly, the characterization of the source of the energetic particles and, finally, the application of laser-accelerated protons for time-resolved radiolysis of glass and water.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Monte Carlo simulation; Three-dimensional; Energy weighting; X-ray; Pixel detector; Charge sharing; Imaging; Medipix; Spectroscopy; Dental diagnosis; Image quality; Electronics; Elektronik;

    Sammanfattning : This licentiate thesis concerns the development and characterisation of X-ray imaging detector systems. “Colour” X-ray imaging opens up new perspectives within the fields of medical X-ray diagnosis and also in industrial X-ray quality control. LÄS MER

  5. 4. Development of Detector Systems for Internal and Fixed Target Heavy Ion Physics Experiments

    Författare :Pavel Golubev; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multi-detector system; VLSI electronics; ultra-thin detectors; heavy ion reactions; nuclear intensity interferometry; Kärnfysik; Nuclear physics; ultra-high vacuum compatibility; Fysicumarkivet A:2003:Golubev;

    Sammanfattning : This thesis deals with intermediate energy heavy ion reactions with the particular aim to study the nuclear matter equation of state which defines the relation between statistical parameters of a fermionic system. The development of equipment for two experiments, CA47 at The Svedberg Laboratory in Uppsala, Sweden and R16 at Kernfysisch Versneller Instituut (KVI), Groningen, The Netherlands, are described.

  7. 5. Fabrication, Simulation and Performance of Ultra-Thin Silicon Detectors-Development of a Detection System for Living Cell Irradiation

    Författare :Naseem Salim; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Abdel; micro-fabrication technology; ultra-thin silicon detector; single ions; SIHF; ΔE detector;

    Sammanfattning : For the development of a Single–Ion Hit Facility (SIHF) for living cells irradiation at the Lund Ion Beam Analysis facility (LIBAF), newly developed pre-cell detectors have been investigated. These detectors can determine the number of ions reaching the sample. Central to the thesis is their fabrication and characterization. LÄS MER
