  • The Last Brick

    (March 8, 2017) Photo: The laying of the last brick. Students (Left to right) Beryl Bell, Sean Vanbergen, and Matthew Palmer set the final graphite brick into place near the UCN cryostat. The graphite is used as a moderator and reflector for neutrons, giving them a chance to enter the superfluid helium in the cryostat and become ultracold.

  • How many neutrons do we make?

    Tuesday, November 22, 2016 (Vancouver). PHOTO: Lori Rebenitsch (U. Winnipeg/U. Manitoba, left) and Tatsuya Kikawa (TRIUMF, right) insert samples for neutron irradiation. The residual activity of the samples will tell us how many neutrons we made, and their temperature.

  • Detectors Made of Diamonds

    We made a particle detector out of diamond, the first application of a detector of this kind in a particle physics experiment. Read about it in Phys. Rev. X.

  • Lithium-6 or not?

    Lithium-6 captures neutrons, splitting apart into an alpha and a triton. If you put regular scintillating glass on top of glass containing Li-6, it makes a very efficient ultracold neutron detector. The trouble is, once they're bonded together, can you tell which side contains the Li-6? Blair Jamieson and Lori Rebenitsch figured out a way that doesn't require an ultracold neutron source!

  • Best Magnetically Shielded Tube

    We developed a new magnetic sensor based on laser excitation of rubidium. We used it to demonstrate a very large magnetic shielding factor for our newly designed magnetic shields. The results were reported in Nuclear Instruments and Methods in Physics Research.

  • Coils inside magnetic shielding

    Our paper in IEEE Magnetics Letters provides new insight into the design of coil structures to be contained within magnetic shielding. The results are useful for designing magnetic shielding and shield-coupled coils for electric dipole moment experiments.

  • Magnetic Shielding in Gradients

    We published an article in AIP Advances on how magnetic field gradients interact with passive magnetic shielding. The results are useful for designing all kinds of magnetic field systems, including those for an nEDM experiment.

  • UCN Project Takes Big Step Forward

    The Ultra-Cold Neutron (UCN) project kicks off the construction of a state-of-the-art experimental area. Upon completion, the UCN facility will produce the highest density of UCN in the world and enable a new generation of experiments into the fundamental interactions of neutrons.

  • Parity Violation in Pion Production

    We searched for predicted large asymmetries in parity-violating pion photoproduction. The conclusion? Surprisingly, not much parity-violation, contrary to the theory!
