Research interests: particle astrophysics, neutrinos and their properties, neutrinoless double beta decay, dark matter. 

Currently(2007) my main project is  the Sudbury Neutrino Observatory(SNO) which has been running since 1999 and was recently turned off in November, 2006.  This experiment has already demonstrated that neutrinos have mass and oscillate.  This is the only conclusive experimental evidence that the standard model of particle physics is incomplete, and has generated considerable interest in the particle physics community.  We have also demonstrated that the standard solar model is substantially correct.  The analysis of the SNO data will continue at least through 2008.  In 2002 we received funding to build the SNOLab underground facility in Sudbury, which will site future experiments involving double beta decay, dark matter detectors, neutrino detectors and other experiments that look for very rare events.   The future experiments that I am starting to work on are DEAP, a liquid argon dark matter detector,  SNO+, an experiment to measure double beta decay, solar neutrinos, neutrino oscillation parameters, and geoneutrinos,  using the SNO detector filled with liquid scintillator.  

Graduate students play a crucial role in these particle astrophysics experiments.  Queen's students have made major breakthroughs and large contributions to SNO in the research for their theses.  We are always interested in recruiting good graduate students, and would encourage interested students to contact me and apply to our program.   For more details on the various physics experiments and the Queen's Particle Astrophysics group, please vist our web site.   

The Sudbury Neutrino Observatory (SNO) is a large international project to study neutrinos from the sun and from supernova.  Neutrinos, which are among the most abundant particles in the universe, are emitted in the nuclear fusion reactions that fuel the sun.  When neutrinos travel through material, they interact only very rarely; even the sun is essentially completely transparent to neutrinos.  This means that neutrinos can be used to directly measure the rate of various nuclear reactions occurring in the core of the sun; all other radiations from the sun are emitted from its surface.  This also means that neutrinos are incredibly difficult to measure, and even the largest practical detectors can only sample a tiny fraction of the neutrinos that pass through.  SNO is designed to measure the number of neutrinos and the energy of neutrinos emitted form the sun and from supernova, as well as to study properties of neutrinos.   SNO has been able to independently measure the energy and flux of electron neutrinos and the flux of all types of solar neutrinos.

The detector is based on 1000 tonnes of heavy water, which is the best material for detecting these neutrinos.  To filter out cosmic rays, the detector is located 2000 meters underground in the Creighton mine near Sudbury.  A large part of the research effort has been to minimize the amount of naturally occurring radioactivity in the heavy water and other materials that make up the detector.

Queen's is participating in several ways.  The administration of the project is through the SNO Institute, located at Queen's.  We are responsible for the photomultiplier tubes, for the calibration of the detector, and for parts of the high purity water system, electronics, data acquisition software, and for analysis of the data.  The detector started operation during 1999, and the focus of the group is on understanding the detector's performance, calibrations, and data analysis.

In terms of analysis, my interests (and possible thesis topics for students) include:

  • Neutrino oscillation parameters
  • The shape of the electron neutrino energy spectrum
  • The ratio of neutral current interactions (in which all types of neutrinos can participate) to charged current interactions (in which only electron neutrinos participate).   We can measure this in several ways- in pure heavy water, by comparing reaction rates with pure heavy water to pure heavy water and salt, and with special neutral current detectors that we added to the detector in 2004.
  • The ratio of charged current to neutrino-electron scattering reactions
  • Seasonal variations in the solar neutrino flux
  • Day/night variations in the neutrino flux

In addition, I am responsible for the calibration of the SNO detector.  This involves the deployment of various sources, and the analysis of subsequent calibration data.  We are finding that it is necessary to continue to develop new sources that will allow us to measure the details of the detector.  Current research projects include:

  • Understanding the detailed optical properties of the detector
  • The energy calibration of the SNO detector
  • Measuring systematic effects in event reconstruction and characterization
  • Measuring neutron responses
  • Determining the shapes of various low energy backgrounds

Before SNO

  • The APEX experiment, at Argonne National Laboratory, which disproved a previously reported experimental phenomenon - that exotic particles are emitted in collisions between very heavy (uranium, thorium, curium) ions.
  • An experiment to look for resonances in positron-electron scattering.
  • Weak radiative lambda decays
  • Rare muon decays (mu -> e gamma, mu -> 3e, mu->e gamma gamma) with the Crystal Box detector at Los Alamos
  • Time reversal violation in beta decay, as measured with polarized Neon-19
  • Searches for axions in nuclear decays
  • Limits on neutrino masses from radiative electron capture in Holmium 163
