  1. 1. Improvement of the AMS-technique and applications to 3H and 59Ni Measurements

    Author : Madis Kiisk; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; accelerator mass spectrometry AMS ; development of AMS technique; 59Ni; tritium; Kärnfysik; Nuclear physics; Fysicumarkivet A:2003:Kiisk;

    Abstract : Accelerator mass spectrometry (AMS) is a highly sensitive technique for counting atoms. Its main advantage in comparison with radiometric methods is the smaller amount of sample required (by a factor of a thousand). The method has a high efficiency and requires only some ten mg of sample material. READ MORE

  2. 2. Development of the Lund AMS Facility for the Detection of 59Ni – with Applications in the Nuclear Industry

    Author : Per Persson; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; AMS; Accelerator mass spectrometry; 59Ni; nuclear waste; chemical cobalt reduction; gas stripper; Nuclear engineering and technology; Kärnteknik; Fysicumarkivet A:2002:Persson;

    Abstract : Accelerator mass spectrometry (AMS) is a highly sensitive method for counting atoms and it is used for detecting very low concentrations of both radionuclides and stable isotopes in small samples. The two major advantages of the AMS method are that the required amount of sample material is very small, but also that the efficiency is rather high, it takes less than an hour to analyse a sample.

  3. 3. Development of the Lund AMS facility for the detection of Al-26 -- with applications in plant ecology

    Author : Mikko Faarinen; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ion source; injector; plant material; Nuclear physics; Kärnfysik; aluminium; Accelerator mass spectrometry; AMS; Fysicumarkivet A:2003:Faarinen;

    Abstract : Accelerator mass spectrometry (AMS) is a highly sensitive technique to count atoms. The method has a high efficiency, which makes it possible to measure small samples in a relatively short time, usually less than an hour. During the work for this thesis, methods have been developed to detect Al-26 at the Lund AMS facility. READ MORE

  4. 4. Experimental data and Total Monte Carlo : Towards justified, transparent and complete nuclear data uncertainties

    Author : Petter Helgesson; Henrik Sjöstrand; Arjan Koning; Stephan Pomp; Dimitri Rochman; Klaes-Håkan Bejmer; Denise Neudecker; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Abstract : The applications of nuclear physics are many with one important being nuclear power, which can help decelerating the climate change. In any of these applications, so-called nuclear data (ND, numerical representations of nuclear physics) is used in computations and simulations which are necessary for, e.g., design and maintenance.
