    Abstract : Ljus är verkligen fantastiskt. Det kan ge oss känslomässiga upplevelser, som när det faller genom en trädkrona i en skog eller vid en blodröd fullmåne, men det gör det också möjligt för oss att uppfatta och förstå vår omgivning. READ MORE

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

    University dissertation from Division of Atomic Physics, Department of Physics, Faculty of Engineering, LTH, Lund University

    Author : Lovisa Senje; Lunds universitet.; Lund University.; [2017]
    Keywords : 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;

    Abstract : 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.
