Postdoctoral Position in Nuclear Science Using Fast Neutrons

Postdoctoral Position in Nuclear Science Using Fast Neutrons

Uppsala University

Uppsala, Sweden

Duties

Your main tasks will be to finalize the NESSA 14-MeV neutron facility and contribute to developing the experimental program at NESSA. Neutrons are a key player in nuclear applications. The availability of neutron sources is especially important for developing and testing detectors for nuclear physics experiments and applications, development and testing of nuclear instruments for verification of nuclear safeguards and disarmament, radiation-shielding studies, development and verification of simulation tools for neutron transports, and irradiation of material and electronics. After the closing of several research reactors and accelerator-based neutron sources (e.g. The Svedberg Laboratory in Uppsala), there is a current lack of neutron facilities in the Nordic countries.

In this project, we test NESSA with the weaker generator, procure a commercially available strong DT generator, and commission the facility. You will work together with researchers from research groups at the division and other interested partners to develop and perform, e.g., test experiments related to fission and fusion research, detector development, electronic irradiations, material analysis, and educational activities for students and industrial partners.

Depending on your experience and background, your tasks may include the following:

  • Procurement of an intense DT generator.
  • Installing and testing of the weak and eventually the strong generator.
  • Testing and calibrating neutron detectors and validation of shielding simulations.
  • Developing of relevant data acquisition systems.
  • Detector development for fusion plasma diagnostics.
  • Development of neutron-activation measurement techniques by using NESSA together with our gamma spectrometry lab.
  • Development of active interrogation techniques for detection of fissile material.
  • Development of education and training activities for students and personnel from industry.
  • Interaction and networking with internal and external users of NESSA.
  • Possibility to get involved into some of the related experimental activities at the division.
  • We also encourage you to develop your individual research direction, and to submit applications to help develop the activities of the division

Requirements

PhD degree in a relevant field, such as nuclear physics or a foreign degree equivalent to a PhD degree. The degree needs to be obtained by the time of the decision of employment. Those who have obtained a PhD degree three years prior to the application deadline are primarily considered for the employment. The starting point of the three-year frame period is the application deadline. Due to special circumstances, the degree may have been obtained earlier. The three-year period can be extended due to circumstances such as sick leave, parental leave, duties in labour unions, etc.

Additional qualifications

The qualifications listed below are meant to help the applicant to point out any relevant experience and expertise. We encourage the submission of an application even if your experience does not match all the listed qualifications.

  • Expertise in experimental techniques using fast neutrons.
  • Experience in the design and optimization of novel radiation detectors.
  • Proficiency in radiation transport simulation with codes such as Geant4 and MCNP.
  • Documented experience in experimental nuclear physics such as fission and fusion research, radionuclide monitoring or gamma spectrometry of environmental samples.
  • Documented experience in active interrogation techniques for detection of fissile material.
  • Working experience with neutron activation measurement techniques.
