1. 16. Study of Radiation Damage of Lead Tungstate Crystals in the Context of CMS ECAL

   Master-uppsats, Institutionen för fysik, kemi och biologi

   Författare :Daniel Edström; [2011]
   Nyckelord :;

   Sammanfattning : The Large Hadron Collider, LHC, at CERN is capable of producing proton-proton collisions at a total energy of 14 TeV. Four principal detectors are installed in the LHC to detect the various particles created in the collisions. LÄS MER

3. 17. Potassium channel AtTPK5 : An essential or redundant regulator of photosynthesis in Arabidopsis?

   Master-uppsats, Institutionen för fysik, kemi och biologi

   Författare :Behrad Shiki Baluch; [2011]
   Nyckelord :Chloroplast; thylakoid; TPK; PCR; ETR; O2-evolution; PAR; PSII.;

   Sammanfattning : It has previously been stated that K+-ions in a plant cell have a counter-balancing role in which the efflux of K+-ions from the thylakoid lumen charge-balance the light-induced proton pumping that is known to occur across the thylakoid membrane, and this in turn stabilizes photosynthetic activity. In the present study, two different types of plants of the same ecotype (Col-0) of Arabidopsis thaliana have been studied: a wild-type and a T-DNA exon-mutant (tpk5-e) that has lost the expression of the protein known as Tandem-pore K+- channel (AtTPK5).

4. 18. Investigation of Ageing effects and Image stability in Hybrid Photon Pixel detectors at the LHCb experiment CERN

   Master-uppsats, Institutionen för fysik, kemi och biologi

   Författare :Albert Mollén; [2010]
   Nyckelord :Ring Imaging Cherenkov detectors; Hybrid Photon Detectors; Ion Feedback; Glow light;

   Sammanfattning : The world’s largest particle accelerator, Large Hadron Collider, located at CERN outside Geneva performed its first proton-proton collisions in November 2009. One of the four main experiments is LHCb, studying rare decays of hadrons containing the beauty quark. LÄS MER

5. 19. Determination of representative spectra for the characterization of waste from a 450 GeV proton accelerator (SPS, CERN)

   Uppsats för yrkesexamina på grundnivå, Institutionen för fysik, kemi och biologi

   Författare :Lisa Bläckberg; [2009]
   Nyckelord :nduced radioactivity; radioactive waste; CERN; characterization; particle spectra;

   Sammanfattning :   Radioactive waste has been accumulated at CERN as unavoidable consequence of the use of particle accelerators. The elimination of this waste towards the final repositories in France and Switzerland requires the determination of the radionuclide inventory. LÄS MER

7. 20. Development of a particle flux detection system for the MERIT high intensity target experiment at CERN

   Master-uppsats, Institutionen för fysik, kemi och biologi

   Författare :Marcus Palm; [2008]
   Nyckelord :diamond; particle; detectors; neutrino; factory; mercury; jet; CERN; MERIT;

   Sammanfattning : The construction of a high intensity neutrino source requires multi megawatt beams and challenges the targets in use. MERIT is a proof-of-principle test for a novel kind of neutrino factory target, employing a 24 GeV/c proton beam and a 1 cm in diameter free mercury jet as beam target. LÄS MER
