👋 Meet Peter Taylor — a new student joining the #DEAP3600 team! He’ll be working on designing the new cryostat to be built and tested at Queen’s University, and on low-level data analysis for one of the beta-backgrounds. Welcome, Peter! ✨

This photo, “Grace under pressure”, was taken by Mary Katherine Keown. The photographer had this to say about it: “Everything — including the coffee — is controlled at SNOLAB. The kind of precision that goes into experimentation at SNOLAB is almost super-human.”

On Aug 1, Michela Lai, Analysis Coordinator of our experiment, began her role as Assistant Professor at Queen’s University, Kingston! She’ll keep working on DEAP-3600, DarkSide-20k & ARGO.
From Cagliari to California to Canada - best of luck, Michela!

If the Big Bang created an equal amount of matter and antimatter, why is antimatter vanishingly scarce in the universe today? SNOLAB is studying neutrino properties to answer this pivotal question. knowablemagazine.org/content/arti...

How a mysterious particle could explain the universe’s missing antimatter

The Big Bang should have produced equal amounts of matter and antimatter, which would have annihilated each other in a spectacular burst of pure energy. But it didn’t. New experiments focused on under...

One of our recent publications appeared in EPJ C last month. Using 3.4 years of data, the #DEAP3600 experiment measured the half-life of a 39Ar isotope—and found it’s significantly longer than expected.

WIMP interactions happen at very low energy, making it important to reduce any backgrounds as low as possible, which is the purpose of our recent hardware upgrades.
