  1. 1. Single-Proton Irradiation of Living Cells - Development of New Tools for Low-Dose Radiation Research

    Författare :Natalia Arteaga; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lithography; UVL; EBL; SeACell; human hepatoma cells HepG2 ; reactive oxygen species ROS ; bystander effect; SU-8; cell recognition; cell irradiation; Single-Ion Hit Facility; low-dose; Fysicumarkivet A:2010:Arteaga Marrero;

    Sammanfattning : A Single-Ion Hit Facility (SIHF) consists of a custom-build facility based in particle accelerators which offers irradiation controlling the number of delivered particles with a precise targeting localization. The irradiation spot can be confined down to the nanometre scale allowing the irradiation of subcellular compartments with a single particle. LÄS MER

  4. 3. Thermal detector with integrated absorber structure for mid-IR gas detection

    Författare :Shakeel Ashraf; Göran Thungström; Peter Enoksson; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal detectors; Thermopile detectors; Infrared absorbers; SU-8 epoxy; Interferometric and Multi-layered absorber; Seebeck coefficient; Molybdenum di-sulfide;

    Sammanfattning : Measurement of the concentration of greenhouse gases, such as carbon dioxide(CO 2 ) and methane (CH 4 ), in the atmosphere has received significant attention in the last few decades. This work focusses on the development of high-performance thermopile detectors for use with the non-dispersive infrared (NDIR) measurements of such gases. LÄS MER

  5. 4. Fabrication and Characterization of Photon Radiation Detectors

    Författare :Claes Mattsson; Hans-Erik Nilsson; Göran Thungström; Mikael Lindeberg; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Detectors; Posistion Sensitive Detectors; Electronics; Elektronik;

    Sammanfattning : This thesis involves a study the fabrication and characterization of photon radiation detectors. The focus has been to develop and improve the performance of optical measurement systems, but also to reduce their cost. The work is based on the study of two types of detectors, the position sensitive detector and the thermal detector. LÄS MER
