Something like the piston in your car's engine if your car was as cold as outer space.
Here's Ray Bunker again.
The reason it has to be kept so cold is the approach for detecting dark matter here is to use large kilogram-scale germanium and silicon crystals.
Dark matter, we hope, comes along, interacts with an atom in the crystal, vibrates it,
And in order to detect the small amount of vibration, you have to reject all the other vibration.
And you do that by making them very cold.
And so then you have a chance of seeing this very rare interaction of a dark matter particle pinging an atom in your crystal.
I'm Ray Bunker.
I'm the director of research at Snow Lab.
What is unique about SNOLAB is its combination of depth and cleanliness.
It is the deepest, cleanest laboratory in the world for conducting underground science of the various types that we pursue.
