Blair Jamieson

My main interests are in experimental subatomic physics, statistically sound precision measurements, fundamental symmetries and tests of the standard model. I am also interested in developing new detectors, and have worked on the large volume Time Projection Chambers (TPC)s for the near detector of T2K. My research program is working toward further understanding the properties of fundamental particles. In particular I am involved in neutrino oscillation studies with the Tokai to Kamioka experiment in Japan, planning for a next generation mega-ton scale water cerenkov detector (Hyper-Kamiokande) and studies of the neutron electric dipole moment using ultra cold neutrons.

The T2K experiment is a long baseline neutrino oscillation experiment, that produces a high intensity muon-neutrino beam at Tokai, Japan. The high intensity beam is detected at a complex of near detectors at 280m from the production target, and at 295km by the Super-Kamiokande detector. A unique feature of the experiment is that the neutrino beam is intentionally observed at 2.5 degrees off axis from its production to reduce the intrinsic electron neutrino background, and to select the muon neutrino energy so that the baseline, L/E, maximizes the oscillation from muon-neutrino to electron-neutrino to give greater sensitivity in measuring the final neutrino mixing parameters. I am a researcher in the T2K collaboration working on the near detector at 280m, the time projection chambers, and the inputs to the oscillation analysis.

Ultra Cold Neutrons

A new high intensity source of Ultra Cold Neutrons is being built at TRIUMF, with help from Japan. Unlike the neutrons inside of a nucleus of an atom, ultra cold neutrons are free to move around and have interesting properties. They are trapped by Earth's gravitational field, they bounce off walls, and can be stored in magnetic bottles. A motivation for producing a high intensity neutron source is that an observation of a permanent electric dipole moment (EDM) of the neutron would imply new physics such as a T-violating process. Another motivation is that if neutrons have an EDM, it would help explain the high value of the baryon-to-photon ratio of the universe that is not accommodated by the standard model parametrization of CP violation. I am the simulation coordinator, with the goals of using the simulation to maximize the experimental sensitivity to a possible neutron EDM. A key part of the neutron EDM experiments is being able to count the number of neutrons that are being measured. As the number of neutrons is increasing, the counting rate needs to be increased as well. To help solve this problem a collaboration with TRIUMF is underway to characterize a new neutron detector technology using a neutron capture coating on scintillator, read out by photomultiplier tube.

Sudbury Neutrino Observatory (Completed Experiment)

My First PostDoc was on the Sudbury Neutrino Observatory (SNO), which was the heavy water Cerenkov detector that solved the solar neutrino problem and made measurements of the solar sector neutrino oscillation parameters. I developed a Markov-Chain Monte-Carlo parameter estimation that was used for the NCD phase analysis of SNO data.

TWIST (Completed Experiment)
My PhD was with the TRIUMF Weak Interaction Symmetry Test (TWIST), which was a high precision measurement of the decay positron spectrum from the decay of highly polarized muons. My thesis was on the first measurement of the parameter describing the asymmetry of the decay, that is sensitive to the mass of a possible right handed W boson in the MSSM model.
