SNOLAB would like to congratulate Dr. David Sinclair, Director of Facilities Development for SNOLAB on his receipt of the inaugural CAP-TRIUMF Vogt medal for his contributions to sub-atomic physics. “I do, of course, feel very honoured to be selected for this award, especially when I reflect on the strength of the field in Canada. I am very pleased that this new award carries Eric Vogtʼs name as I have always respected him as one of the great scientists and scholars in the field, whose work helped to establish the position Canada currently has.“ said Dr. Sinclair.

The HALO experiment located at SNOLAB went live as of today.

The HALO experiment is acquiring data on all 64 channels, all 128 NCD's (Neutral Current Detectors). There is still much work to do on this experiment but this is an exciting milestone for the experiment. 

New data are being reported by the COUPP (Chicagoland Observatory for Underground Particle Physics) from the operation of a 4.0 kg CF₃I bubble chamber at SNOLAB. The effectiveness of ultrasound analysis in discriminating alpha decay background events from single nuclear recoils has been confirmed, with a lower bound of >99.3% rejection of alpha decay events. Twenty single nuclear recoil event candidates and three multiple bubble events were observed during a total exposure of 553 kg-days distributed over three different bubble nucleation thresholds.
