  2. 1. Precision mass measurements : Final limit of SMILETRAP I and the developments of SMILETRAP II

    Author : Andreas Solders; Reinhold Schuch; Juha Äystö; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SMILETRAP; Precision mass spectrometry; Penning trap; Atomic mass; Highly charged ions; Low energy ion storage; Time of flight ion cyclotron resonance; High frequency; Proton mass; QED; g-factor; Physics; Fysik; Physics; fysik;

    Abstract : The subject of this thesis is high-precision mass-measurements performed with Penning trap mass spectrometers (PTMS). In particular it describes the SMILETRAP I PTMS and the final results obtained with it, the masses of 40Ca and that of the proton. READ MORE

  4. 2. Fragmentation in Proton-Nucleus Reactions from 100 to 1400 MeV

    Author : Henrik Jäderström; Lars Wesretberg; Yuri Murin; Kjell Aleklett; Haik Simon; Uppsala universitet; []
    Keywords : Nuclear physics; proton; deuteron; 20Ne; 28Si; Xe; nuclear reactions; inverse kinematics; recoils; intermediate mass fragments; angular distribution; DCM model; JQMD model; CFEM model; single event upset; Kärnfysik;

    Abstract : The heaviest fragments, recoils, have been studied in proton and deuteron induced 28Si reactions and proton-20Ne reactions at 100-300 MeV per nucleon. Inclusive charge and angular distributions and coincidences between He nuclei and recoils have been compared to two theoretical models, Dubna Cascade Model and JAERI Quantum Molecular Dynamics.

  5. 3. Charged kaon and proton production in B-hadron decays

    Author : Fredrik Tegenfeldt; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Högenergifysik; LEP; DELPHI; B-hadron; proton; kaon; Strålningsvetenskap; Radiation biology; Strålningsbiologi; High Energy Physics; Högenergifysik;

    Abstract : The production of charged kaons and protons in B-hadron decays has been measured in e+e- annihilations at centre-of-mass energies corresponding to the Z0 mass. In total 1.6 million hadronic Z0 decays were analysed, corresponding to about 690000 B-hadron decays. READ MORE

  6. 4. Electrochemical characterizations of conducting redox polymers with proton traps : Enabling proton cycling in aprotic systems for high potential energy storage

    Author : Lisa Åkerlund; Martin Sjödin; Rikard Emanuelsson; Adolf Gogoll; Maria Strömme; Carita Kvarnström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Conducting redox polymers; Proton trap; Quinones; Organic energy storage; Organic batteries; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Abstract : Floods, droughts and unpredictable weather could be the new reality for millions of people in a near future, unless we drastically decrease our greenhouse gas emissions to prevent the global average temperature from increasing even further. Material innovations will most certainly be essential for many of the technical solutions needed in order to tackle environmental issues. READ MORE

  7. 5. Chiral Recognition by Means of Mass Spectrometry

    Author : Oleksii Rebrov; Mats Larsson; Per Johnsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chirality; Mass spectrometry; Chiral recognition; Gas phase; kemisk fysik; Chemical Physics;

    Abstract : This thesis is based on experimental studies of chiral ions in gas-phase. Electrospray ion source platform (Stockholm University) and commercially available Quadrupole Time-of-Flight mass spectrometer have been used in our studies. READ MORE
