Degree projects - HIBEAM & NNBAR

Degree Projects HIBEAM & NNBAR

The Lund HIBEAM/NNBAR group plays a leading role in a wide range of activities within the HIBEAM and NNBAR experimental programme at the European Spallation Source (ESS). Our research spans many areas of experimental particle and neutron physics, including beamline design, magnetic shielding, detector development, background studies, neutron optics, and searches for physics beyond the Standard Model. In particular, our group is leading the development of key components of the HIBEAM/NNBAR annihilation detector, with a particular focus on the Time Projection Chamber (TPC). We are also leading the construction of a magnetically controlled neutron beamline for novel searches for axion-like particles (ALPs), as well as the development of a next-generation neutron electric dipole moment (nEDM) experiment at ESS.

We offer Bachelor's and Master's degree projects in detector physics, simulations, instrumentation, data analysis, and fundamental physics.

Examples of degree projects

  • Background studies for the HIBEAM/NNBAR experimental programme at ESS.
  • Design and optimisation of the vacuum system for the NNBAR experiment.
  • Study of the impact of vacuum windows on the performance of the HIBEAM beamline.
  • Studies related to next-generation neutron electric dipole moment (nEDM) experiments.
  • Design and sensitivity studies for axion-like particle (ALP) search experiments using neutron beams
  • Design and performance studies of Time Projection Chambers (TPCs) for neutron and antineutron detection.
  • Simulation and optimisation of annihilation detectors for the NNBAR experiment.
  • Development of reconstruction and particle identification algorithms, including machine learning techniques.
  • Development of background suppression techniques, including cosmic-ray rejection.
  • Benchmarking and characterization of detector prototypes developed in collaboration with Uppsala and Stockholm Universities.

Students interested in experimental particle physics, detector development, simulations, and searches for new physics are encouraged to contact us to discuss potential degree projects and research opportunities within the HIBEAM/NNBAR programme.
