Postdoctoral Fellow on the nEXO Experiment

One postdoctoral position is available immediately to work with the Enriched Xenon Observatory (EXO) group at Laurentian University (Sudbury, Ontario). The successful candidate will focus research efforts on R&D for the next-generation experiment nEXO. The Particle Astrophysics Group at Laurentian provides a dynamic environment and maintains very strong interactions with researchers at nearby SNOLAB, where nEXO intends to be located.

The EXO program searches for neutrino-less double beta decay in 136Xe. EXO–200, a 100-kg class detector filled with enriched liquid xenon, has successfully finished data-taking in 2018 at the WIPP underground site in New Mexico. EXO–200 measured the 2νββ transition rate with the highest precision of all 2νββ nuclei and probed the 0νββ transition rate down to an effective neutrino mass close to 100 meV. EXO–200 also informs the design of the 5-tonne nEXO detector, with a planned sensitivity on the effective neutrino mass covering the inverted hierarchy.

The successful candidate will take leading roles in one or more of these areas:

  • characterization of the photomultipliers for the nEXO outer detector;
  • simulations and physics potentials of nEXO;
  • analysis of EXO-200 data;
  • R&D on isotopic xenon enrichment.

Candidates must hold a recent Ph.D. degree in experimental particle or nuclear physics at the time of appointment. Demonstrated experience is required in detector development, simulation and/or data analysis. It is expected that the candidate will be familiar with high energy physics tools such as ROOT and/or GEANT4.

The initial appointment will be for two years, with possible extension. Applicants should forward a Curriculum Vitæ and a statement of research interests, by email only, and arrange for three reference letters to be sent directly to:
