It was fantastic to have the benefit of Hilding's expertise, insights, and wisdom last week at #SNOLAB. I learned a lot about the view of many Indigenous peoples regarding the connection of land and sky, and the erasure of boundaries between those […]

A wide-angle lens photo of the interior of the PICO-500 water tank, showing the suspended steel pressure vessel and support structure for aiding in construction of the experiment. I stopped to take this when moving between the PICO-500 and PICO-40L sites.
Had another great day working in the underground laboratory at #SNOLAB. I joined my PICO #darkmatter detector colleagues on a few projects, including operations improvements for the ongoing PICO-40L experiment and some efforts to support […]

An oscilloscope screen shows voltage versus time. A pulse indicates a small avalanche of electrons inside a photomultiplier tube connected through electronics to the scope. This is “dark noise”, the random internal electronic noise of the tube once the voltage is high enough to allow for the photoelectric effect. This is a sign the tube is working!
An inspection of retroreflector material on a cone section. The material needs to be in good enough condition to reflect light back onto the bubble chamber and illuminate bubbles forming inside the chamber.
Another great day working in the underground laboratory at #SNOLAB. My focus was on supporting the #PICO bubble chamber team today. Activities included starting the check of photomultiplier tubes (PMTs) in an underground “dark box” setup; and […]

The interior blue doors that originally led to the “drys” where people changed from mine gear into cleanroom clothing, and those connecting to the “car wash” where material was taken in and cleaned before entering the SNO experiment.
Connections to a vacuum system for the PICO experiment.
The original main entrance “blue doors” that allowed people (smaller door, left) and equipment (larger double doors) into the SNO experiment. The pairs of doors here and down the hall form a kind of “airlock” system to keep dust from penetrating into the clean spaces that housed SNO. Now, in the expanded SNOLAB, these doors are nestled inside the much larger 5000-square-metre clean lab.
I was thrilled to be working in the 2km-deep underground laboratory yesterday. This is the flagship laboratory location for #SNOLAB
I focused on working with teams on the #cryogenic distillation column (“#Xenon Still”) and the #PICO #darkmatter […]

Students at #SNOLAB are starting to engage in our common orientation for research experiences. One particle that comes up really early is the #muon. Students often don't learn about subatomic particle properties other than #electrons, #protons, and #neutrons until late in university. I made this […]
It was great to welcome to SNOLAB a new winter class of #students and share with them pieces of the #SNOLAB science portfolio. I loved the questions afterward about #neutrino mass measurement!

A plastic container holds water and two metal electrodes are dipped in the container. Various components hold the electrodes in place and connect them to a power supply.
A team at #SNOLAB is getting ready to conduct a program of research and development on the #electroforming of metals for science-grade applications. We have learned a lot from the researchers and labs who have made great strides in this before us […]

There is very little else that is more satisfying than a busy electronics crate in an experimental data acquisition system.

9/10 Canada is at the forefront of this search. The expanded #SNOLAB facility, deep underground in a Sudbury mine, is now home to more than a dozen new experiments designed to be the first to solve the dark matter mystery.

SNOLAB is more than a global leader for underground science and discovery; we are Ontario’s training ground for scientists, technologists, and tradespeople … talent made right here in Ontario.

It was an honour to be able to support the tour for Minister Quinn and MPP Rosenberg at #SNOLAB this past week. I am especially proud of the work that scientific staff, as well as students and post-docs working on their experiments, did to share the human stories of underground science and the […]
A plastic part being 3D printed
Good things are happening on our underground 3D printer at #SNOLAB! I am very excited for the next phase of the student-led cloud chamber project, as we take this design to a new phase.
I am sad that I cannot partake in #monsterdon tonight … I have to get up early to go work in the underground lab at #SNOLAB. I wish everyone partaking in the community movie watch a good view. I snuck a peak at “Frankenstein Meets the Space Monster” and it’s … um … it’s.

#SNOLAB’s monitoring station is CAN7023 and on a typical day sees a gamma radiation level of about 50-70 nanoSieverts per hour (nSv/h). Typical ambient radiation levels are 2 mSv in a year. Gamma radiation would thus typically contribute 0.5 mSv in a year, or about 1/4 of the […]
There is also a growing body of evidence that, at a minimum, some microorganisms suffer negative health consequences when DEPRIVED of ambient (background) radiation. Since life evolved in an ambient radiation environment, this would be evidence that too LITTLE radiation can have negative health […]
