    Sammanfattning : Light-ions (protons, deuterons, tritons, 3He and α articles) production in the interaction of 175 MeV neutrons with iron and bismuth has been measured using the Medley setup at the The Svedberg Laboratory (TSL) in Uppsala. These measurements have been conducted in the frame of an international collaboration whose aim is to provide the scientific community with new nuclear data of interest for the development of Accelerator Driven Systems, in the range of 20 to 200 MeV.

    Sammanfattning : The present thesis describes two experiments performed in the storage ring CELSIUS at The Svedberg Laboratory in Uppsala. In the first experiment the importance of three - nucleon clustering in the six - nucelon system was investigated. The total cross section for the production of the ground state and the 3. LÄS MER

  4. 3. Production of high quality 11C beams for radiation treatment and accurate PET-CT dose delivery verification

    Sammanfattning : Radiation therapy with external beams of positron emitter light ions offers the optimal solution for simultaneously treating and in vivo monitoring the delivery of the dose in 3D with Positron Emission Tomography (PET) or PET-Computed Tomography (CT) imaging. Specifically, positron emitter light ion beams merge the main distinctive advantages of light ion therapy, namely a high conformal and biological effective dose delivery to the tumor, an optimal penumbra, and sparing of the surrounding normal tissues, with the advantage of a high β+-activity signal mainly produced directly by the beam itself, and therefore not primarily dependent on the specific stoichiometry of the body tissues.
