      Particle computed tomography (pCT) is an emerging imaging modality that promises to reduce rangeuncertainty in particle therapy. The Bergen pCT collaboration aims to develop a novel pCT prototype basedon the ALPIDE monolithic ...
    • A Digital Tracking Calorimeter for Proton Computed Tomography 

      Pettersen, Helge Egil Seime (Doctoral thesis, 2018-05-29)
      Cancer is a destructive disease, in which tumor cells grow out-of-control, halting organ function. Its treatment is threefold: Radical surgery, chemotherapy and radiation therapy. Their relative usage is determined by ...
    • The Higgs Boson in Less Constrained Supersymmetric Models 

      Pettersen, Helge Egil Seime (Master thesis, 2012-06-01)
      In this thesis, we explore the phenomenological minimal supersymmetric standard model (pMSSM) in the context of the Higgs boson. If the emerging results from the LHC are real, will the pMSSM be able to accommodate this? ...
    • In-situ measurements of rare earth elements in deep sea sediments using nuclear methods 

      Obhođaš, Jasmina; Sudac, Davorin; Meric, Ilker; Pettersen, Helge Egil Seime; Uroić, Milivoj; Nađ, Karlo; Valković, Vlado (Peer reviewed; Journal article, 2018-03-21)
      The prospecting activities for finding new rare earth elements (REE) sources have increased greatly in recent years. One of the main discoveries was announced in 2011 by Japanese researchers who found large quantities of ...
    • Optic nerve constraints for carbon ion RT at CNAO ? Reporting and relating outcome to European and Japanese RBE 

      Dale, Jon Espen; Molinelli, Silvia; Vitolo, Viviana; Vischioni, Barbara; Bonora, Maria; Magro, Giuseppe; Pettersen, Helge Egil Seime; Mairani, Andrea; Hasegawa, Azusa; Dahl, Olav; Valvo, Francesca; Fossati, Piero (Peer reviewed; Journal article, 2019)
      Background and purpose: Until now, carbon ion RT (CIRT) dose constraints for the optic nerve (ON) have only been validated and reported in the NIRS RBE-weighted dose (DNIRS). The aim of this work is to improve CNAO’s ...
