Doctoral student position in applied nuclear physics – Fission yield measurements with VERDI
Uppsala University is a comprehensive research-intensive university with a strong international standing. Our mission is to pursue top-quality research and education and to interact constructively with society. Our most important assets are all the individuals whose curiosity and dedication make Uppsala University one of Sweden’s most exciting workplaces. Uppsala University has 44.000 students, 7.100 employees and a turnover of SEK 7 billion.
The Division of Applied Nuclear Physics conducts research in the areas of nuclear reactions (for applications like nuclear energy, cancer therapy or transmutation of nuclear waste), nuclear fuel diagnostics and safeguards, neutron diagnostics for fusion energy and interaction of high velocity ions in various materials. The nuclear reactions research group is devoted to measurements and evaluations of nuclear data for applications, for example nuclear energy, nuclear medicine and electronics. With our collaborators, primarily at laboratories in Belgium, Finland and France, we study nuclear reaction cross sections, fission yields and neutron multiplicities, light ion production, single event upsets, and so on. We are also involved in the development of the nuclear reaction code TALYS and the nuclear data library TENDL.
Description of the project: Nuclear fission is a fascinating topic in where the interplay between the fundamental forces of nature give rise to exciting quantum phenomena. A solid understanding of fission, the resulting fragment mass distributions, neutron evaporation, and γ-ray emission, helps us to understand a range of topics; how exotic nuclei are formed in the universe as well as improve the safety and efficiency of future nuclear power systems.
In collaboration with the Joint Research Centre (JRC) of the European Commission in Belgium, we develop the state-of-the-art nuclear instrument (VERDI) which stands for “VElocity foR Direct particle Identification”. With VERDI we are able to measure the velocities and energies of both produced nuclei, which allows a mass determination. In order to obtain precise mass measurements, both fragment velocities must be determined with high precision. One main challenge is to deduce the correct time-of-flight from the Si detector signals.
The scientific aim of the project is to improve the VERDI setup and to perform high-precision experimental studies of neutron-induced fission, of relevance for future reactor systems. High-precision correlated data (fission yields, kinetic energies and neutron emission) improve fission modelling and the evaluation of nuclear data relevant for reactor operation. Experiments are planned first on Cf-252(sf) for calibration and later on thermal fission of U-235.
During the Ph.D., the student will gain profound knowledge in nuclear reactions and instrumentation used in nuclear physics research. The Ph.D. student will get specialized in the field of fission dynamics, ionizing radiation, radiation measurements with particular emphasis on fission fragments, neutron and gamma-ray detection.
As a doctoral student at our division, you will work in a multi-cultural environment and you will have an active role in the group activities such as seminars, workshops and courses. At the same time, you will be expected to work independently and to take personal responsibility for the progression of the project. Since most of our experimental work is located to different European facilities you will be spending extended periods of time abroad, especially at JRC in Belgium. Your main task will be to conduct fission yield experiments, to collect and analyse data and to compare the results to existing data-sets and model calculations. You will also perform computer simulations of the experimental set-up in order to improve the performance.
