  3. 7. Characterization of interface states & radiation damage effects in duo-lateral PSDs : Using SEM microscopy and UV beam profiling techniques

    Författare :Omeime Xerviar Esebamen; Göran Thungström; Hans-Erik Nilsson; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : There has been an increase in the use of duo‐lateral position sensitive detectors inpractically every radiation and beam detection application. These devices unlike other light detection system utilize the effect of the lateral division of the generated photocurrent to measure the position of the integral focus of an incoming lightsignal.

  4. 8. Simulation, Measurement and Analysis of the Response of Electron- and Position Sensitive Detector

    Författare :Omeime Xerviar Esebamen; Hans-Erik Nilsson; Göran Thungström; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Different methods exist in relation to probing and investigating thephysical and structural composition of materials especially detectors whoseusage have become an integral part of radiation detection. The use of thescanning electron microscopy is just one of such exploratory methods. LÄS MER

  5. 9. Antenna-based passive UHF RFID sensor tags : Design and application

    Författare :Jinlan Gao; Hans-Erik Nilsson; Johan Sidén; Emmanouil Tentzeris; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : RFID, as a low cost technology with a long life time, provides great potential for transmitting sensor data in combination with the ordinary ID number. The sensor can, for example, be integrated either in the chip or in the antenna of an RFID tag. LÄS MER

  7. 10. Aggregates in Concrete Mix Design

    Författare :Yahya Ghasemi; Mats Emborg; Andrzej Cwirzen; Martin Nilsson; Gram Hans-Erik; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mix design; water layer theory; particle packing; aggregates; specific surface area; Byggproduktion; Construction Engineering and Management;

    Sammanfattning : The importance of studying the behaviour and properties of concrete can be highlighted by considering the fact that concrete is the most used man-made material in the world. The very first step in making concrete is its mix design and deciding the type and amount of constitutes used in the production of concrete which should fulfil the requirements of the final product.
