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:

Looking for Graduate Students

Graduate Studies in Astroparticle Physics

Prof. Caio Licciardi invites applications from students interested in pursuing a M.Sc. in Physics or Ph.D. in Materials Science at the Department of Physics at Laurentian University.

The department is engaged in intensive research in Particle Physics and Medical Physics. The local Particle Astrophysics Group has strong ties with SNOLAB, a 2-km underground science laboratory. SNOLAB is the original site of the Sudbury Neutrino Observatory (SNO) experiment, recognized in the 2015 Nobel Prize for Physics. In addition, Laurentian is a member of the newly created Canadian Particle Astrophysics Research Centre. Exploiting these advantages, we are able to ensure that each student receives world-class education, and become well prepared for a future in the academia or industry.

One of the most outstanding problems yet to be understood is that of the properties of the neutrinos. Recent observations proved that neutrinos have mass, which has implications in several areas from cosmology to elementary particle physics. In particular, this may shed light in the origin of the Universe. Assigning mass to neutrinos allows the possibility for these particles to be their own antiparticles. The most sensitive probe to this nature of the neutrino is searching for neutrinoless double beta decay, a hypothetical mode in which two electrons are emitted with no neutrinos. Our group has a leading participation in the Enriched Xenon Observatory (EXO), both in the successful EXO-200 detector and in the design of the nEXO experiment. EXO-200 has made the first observation of the two-neutrino double beta decay in Xe-136, holding its most precise measurement, and has limits to the neutrinoless mode placed among the world’s best.

Thesis work includes a combination of physics analysis, detector operations, and development of hardware techniques within the EXO program. Ph.D. students are expected to take responsibility for project components. A scholarship is included for the successful applicants.
