  2. 1. Modeling of radiative processes in organic scintillators

    Author : Jenny Nilsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis presents the development of a Monte Carlo calibration of a whole body counter (WBC), consisting of four large plastic (organic) scintillators, used for determine the body burden of gamma-emitting radionuclides. A scintillator emits optical photons after energy has been deposited by an ionizing particle in the scintillator material. READ MORE

  4. 2. Development and Use of Neutron Scintillator Systems for Fusion Plasma Diagnostics

    Author : Magnus Hoek; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic scintillators; neutron spectrometry;

    Abstract : This thesis reports on research and development work, made in connection with the use of organic scintillators, for neutron spectrometry. It also gives a general review on the use of organic scintillators for the detection of neutrons generated from fusion of deuterium (D) and fusion between a mixture of deuterium and tritium (T) in thermonuclear plasmas.

  5. 3. The Anticoincidence Shield of the PAMELA Satellite Experiment

    Author : Silvio Orsi; KTH; []
    Keywords : astrophysics; particle physics; antimatter; organic scintillators;

    Abstract : The PAMELA space experiment is scheduled for launch towards the end of 2004 on-board a Russian Resurs DK1 satellite, orbiting Earth at an altitude of 300– 600 km. The main scientific goal is a study of the antimatter component of the cosmic radiation. The semipolar orbit (70. READ MORE

  6. 4. Studies of cosmic rays with the anticoincidence system of the PAMELA satellite experiment

    Author : Silvio Orsi; Mark Pearce; Martin Pohl; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; astrophysics; astroparticle physics; antimatter; organic scintillators; cosmic rays; trapped particles; Astroparticle physics; Astropartikelfysik;

    Abstract : PAMELA is a satellite-borne experiment designed to study the charged component of the cosmic radiation of galactic, solar and trapped nature. The main scientific objective is the study of the antimatter component of cosmic rays over a wide range of energies (antiprotons: 80 MeV–190 GeV, positrons: 50 MeV–270 GeV). READ MORE

  7. 5. Neutron-Induced Scintillation in Organics

    Author : Nicholai Mauritzson; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; liquid organic scintillator; oil; time-of-flight; neutron tagging; light yield; simulation; calibration; NE 213A; EJ 305; EJ 331; EJ 321P; Source Testing Facility; pedagogy; Fysicumarkivet A:2023:Mauritzson;

    Abstract : Neutrons are widely used as probes of matter to study materials in a broad range of fields from physics, chemistry and medicine to material sciences. Any application utilizing neutrons needs to employ a well-understood and optimized neutron-detector system. READ MORE
