CLOSED: EXO Research Associate Positions

Friday, July 29, 2016


The Carleton University Neutrino Physics Group invites applications for up to two Research Associate positions on the Enriched Xenon Observatory (EXO) experiment. The EXO group is actively pursuing 3 major activities: the EXO-200 detector operation which is resuming data collection from its liquid-phase TPC located at WIPP in the search for the neutrinoless double beta decay of 136Xe; work to support and enhance the design of nEXO, a 5 tonne liquid xenon detector proposed for installation at SNOLAB; and work to develop a future experiment with sensitivity to the normal hierarchy. Successful applicants are expected to contribute within the scope of these activities.

It is anticipated that both of the Research Associates will work on hardware projects including simulation studies to support the hardware development. Initially, one will focus on developing very sensitive ion detection and identification techniques for a program of barium tagging. The aim of this technique is to reduce the background in the double beta process by identifying the 136Xe decay daughter ion 136Ba. This study will exploit and extend the systems developed at Carleton for laser identification of the barium ions in a Paul trap. The work will involve collaboration with the EXO groups at McGill and TRIUMF. The other Research Associate will work on developing and testing of new concepts to be used on the cryogenic, liquid-xenon detector nEXO.

It is expected that both successful applicants will participate in the operations of EXO-200 at the WIPP site in New Mexico. Opportunities are available to contribute to the continued analysis and physics searches with EXO-200 data. The candidates would also be expected to help with the supervision of our students.

We seek candidates who hold a Ph.D. degree (or will graduate soon) in experimental particle or nuclear physics. The applicants should have an interest in hardware and neutrino physics. Experience in data acquisition systems, liquid and gaseous detectors, vacuum systems, electronics, underground physics, ion manipulation/trapping, ion physics or low background studies would be an asset.

The candidate should send by email a CV, a statement of research interests and arrange to have three letters of recommendation sent to:

Professor Thomas Koffas
Department of Physics, Carleton University

We will consider applications as soon as they are complete and would like to make an appointment as soon as possible. We encourage all qualified persons to apply.
