Aksel Hallin

Aksel Hallin, PhD, is a Professor of Physics at the University of Alberta's Faculty of Science. He leads experimental astroparticle physics research, focusing on dark matter detection (DEAP-3600/DarkSide-20k) and neutrino studies (SNO+, SNO). His work includes designing detectors like the acrylic cryostat for DEAP-3600 and the anode/cathode system for DarkSide-20k, emphasizing ultrapure materials and background reduction. He holds roles at SNOLAB and Gran Sasso, with expertise in detector construction, data analysis, and radioactive contamination control. His courses include PHYS 234: Introductory Computational Physics.

Education:

• PhD (1983) Princeton University
• MA (1979) Princeton University
• BSc (1977) University of British Columbia

Research Interests: Dark matter particle identification, neutrino oscillations, neutrinoless double-beta decay, liquid argon detectors, and precision radioactivity measurement. His labs include radon-free clean rooms and gamma-ray detection systems. Collaborates globally on projects like the Global Argon Dark Matter Collaboration.

Grants/Contributions: CFI grants supported DEAP-3600 construction. Alberta team contributions include acrylic components, simulation algorithms, and radon measurement systems. Active in SNO+, analyzing solar neutrinos and reactor antineutrinos.

Labs/Teams: Leads University of Alberta teams on DEAP-3600, DarkSide-20k, and SNO+. Collaborates with Queen’s University, Los Alamos National Lab, and European institutions.
