  2. 1. Fabrication, Simulation and Performance of Ultra-Thin Silicon Detectors-Development of a Detection System for Living Cell Irradiation

    Author : Naseem Salim; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Abdel; micro-fabrication technology; ultra-thin silicon detector; single ions; SIHF; ΔE detector;

    Abstract : For the development of a Single–Ion Hit Facility (SIHF) for living cells irradiation at the Lund Ion Beam Analysis facility (LIBAF), newly developed pre-cell detectors have been investigated. These detectors can determine the number of ions reaching the sample. Central to the thesis is their fabrication and characterization. READ MORE

  4. 2. Fabrication and Characterisations of New Ultra-thin Silicon Detectors as Pre-Cell Hit Detectors for a Cell Irradiation Facility at LIBAF

    Author : Naseem Salim; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SIHF; ΔE detector; single ions; Ultra-thin silicon detector and Microfabrication;

    Abstract : For the development of single–ion irradiation system for living cells at the Lund Ion Beam Analysis facility (LIBAF) newly developed pre-cell (PC) detectors have been investigated. Central to the thesis is the fabrication and initial characterization of more than 100 ultra-thin silicon detectors having different thicknesses down to 5 μm with active areas ranging from 0.

  5. 3. Measurement of the Reaction pp→ppπ+π-π0 with CELSIUS/WASA at 1.36 GeV

    Author : Marek Jacewicz; Sven Kullander; Hans Ströher; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; Elementarpartikelfysik; Elementary particle physics; Elementarpartikelfysik;

    Abstract : A versatile detector setup prepared by the CELSIUS/WASA collaboration for exclusive studies of rare processes produced in proton and deuteron collisions with hydrogen and deuterium pellet targets is presented. For the near-threshold production of light mesons, π0 and η, the scattered beam and target particles are measured in the forward detector, while the products of the decaying mesons are registered in a central detector covering close-to-4π sr.

  6. 4. Characterization and Optimization of Silicon-strip Detectors for Mammography and Computed Tomography

    Author : Han Chen; Mats Danielsson; cheng xu; Andrew Maidment; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mammography; anti-scatter grid; photon-counting; spectral computed tomography; silicon strip; ASIC; energy resolution; Compton scatter; material decomposition; K-edge imaging; Medical Technology; Medicinsk teknologi;

    Abstract : The goal in medical x-ray imaging is to obtain the image quality requiredfor a given detection task, while ensuring that the patient dose is kept as lowas reasonably achievable. The two most common strategies for dose reductionare: optimizing incident x-ray beams and utilizing energy informationof transmitted beams with new detector techniques (spectral imaging). READ MORE

  7. 5. Pionic Fusion Study of the 6He Halo

    Author : Linda Gerén; Christoph Bargholtz; Per-Erik Tegnér; Lennart Isaksson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : The structure of the halo nucleus 6He has been investigated in a pionic fusion experiment at the CELSIUS storage ring facility in Uppsala. The 4He(d, 6He)π+ reaction was studied 0.6 - 5.0 MeV above threshold in the centre-of-mass frame with a deuteron beam incident on a 4He gas target. READ MORE
