  1. 1. Test setup for LDMX HCal readout

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Joshua Greaves; [2020]
    Keywords : Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

    Abstract : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.

  2. 2. Initial Characterization of a Pixelated Thermal-Neutron Detector

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Amanda Jalgén; [2017]
    Keywords : Neutron; detector; spallation; scintillator; photomultiplier tube; Physics and Astronomy;

    Abstract : The purpose of this project was to develop a better understanding of the re- sponse of a pixelated thermal-neutron detector, which will be used as a thermal- neutron detector at one of the beam lines at the European Spallation Source in Lund, Sweden. The detector consists of a thin Lithium6-glass scintillator, a multi-anode photomultiplier tube and associated read-out electronics. READ MORE

  3. 3. Development of a Detector System for Detection of Thermal Neutrons from Spent Nuclear Fuel

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Daniel Söderström; [2016]
    Keywords : neutron detection; neutron; 10B; boron-10; nuclear physics; boron; neutron detector; scintillator; boron carbide; B4C; nuclear fuel; repository; SKB; Physics and Astronomy; Technology and Engineering;

    Abstract : The nuclear reaction 10B(n,alpha)7Li* was utilised to develop a neutron detection system. This system has the purpose of being used to detect the thermal neutron radiation emitted by spent nuclear fuel, before it is transported to a final repository. READ MORE

  4. 4. Flow Cytometry Sensor System Targeting Escherichia Coli as an Indicator of Faecal Contamination of Water Sources

    University essay from Linköpings universitet/Teknisk biologiLinköpings universitet/Tekniska högskolan

    Keywords : Sensor system; Water quality; Flow cytometry; Faecal contamination; Faecal indicator; Escherichia Coli; Untreated water; Near infrared light; NIR; Antibody; Immunoglobulin; IgY; Alexa Fluor 790; Photomultiplier tube; CMOS; camera.;

    Abstract : Poor water quality is a global health concern affecting one billion people around the world. It is important to monitor water sources in order to maintain the quality of our drinking water and to avoid disease outbreaks. READ MORE

  5. 5. Upgrading the Control and Monitoring system for the TOFOR neutron time-of-flight spectrometer at JET

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Johan Valldor-Blücher; [2013]
    Keywords : control and monitoring system; upgraded control and monitoring system; C Mu system; C M system; TOFOR; spectrometer; time-of-flight; JET; fusion; plasma diagnostics; energy spectrum; monitoring time delays; pulse reconstruction; timing measurements;

    Abstract : This report describes the development and testing of the upgraded Control and Monitoring (C&Mu) system for the TOFOR neutron spectrometer. TOFOR is currently performing plasma diagnostics for the JET experimental fusion reactor. The purpose of the C&Mu system is to enable monitoring of the amplitude dependent time delays of TOFOR.
