Uppsala University is one of the leading universities in the Nordic countries and is ranked among the top 100 universities in the world. The Faculty of Sciences and Technology alone has about 1600 employees and 9000 students, and has an annual turnover of about 140 M€.

Relevant experience

Uppsala University contributes to CHANDA with the Division of Applied Nuclear Physics (UU-ATK) and the Svedberg Laboratory at Uppsala University (UU-TSL).

The Nuclear Reactions research group has a long standing experience in measuring data on neutron induced reactions at both the quasi-monoenergetic neutron beam of UU-TSL and other facilities and is currently or has previously participated in FP5 (HINDAS), FP6 (EFNUDAT, CANDIDE and EUROTRANS), and FP7 (ERINDA, ANDES). The group is furthermore part of the Generation-IV Industry-University Swedish consortium (GENIUS) and has recently extended its activities into the field of nuclear data evaluation and development of the so-called Total Monte Carlo method. In addition to its research activities, the group has a strong activity in teaching reactor physics and closely related topics to both students and industry employees. UU-ATK is involved in WP8, WP9 and WP 13 of DMC. UU-ATK will develop tools for precision measurement of fission cross-sections and anisotropy at NFS (Task 8.1), participate in advanced fission yield measurements at NFS and JYFL (Task 8.5), work on further development of the TALYS code, especially it fission yield models (Task 9.2), and take a leading role in the organization of summer schools (Task 13.2)

The Svedberg Laboratory is an accelerator facility belonging to Uppsala University. The laboratory operates the Gustaf Werner cyclotron for production of high-energy fields of protons, neutrons, and heavy ions. Two neutron facilities are available:

  1. The Quasi-Monoenergetic Neutron facility (QMN), with the peak energy selectable within the 20-175 MeV range and the peak flux density up to 3·105 cm-2s-1.
  2. The Atmospheric Neutrons from thIck TArget (ANITA) facility, with a continuous spectrum from thermal energies up to ~180 MeV and the flux density ~ 106 cm-2s-1 for neutrons above 10 MeV. The neutron facilities have properties that are currently not available elsewhere in Europe. UU-TSL is capable of offering at least 2000 hours of beam time per year for users. During the last years, more than 600 external users from 23 countries around the world have visited the TSL irradiation facilities. The role of UU-TSL in the project is to provide access to its irradiation facilities and to support experiments of external users by its measurement capabilities and the expertise of its staff members.
