This is the detector I am working with. It’s used for direct dark matter detection. Today, my colleagues came up with a new setup which would help to detect dark matter even more. They are going to use an extra skin on top of the detector, which would hold 230 tons of ultrapure water! Just stop for a second and think about these numbers. The detector itself is located very deep (around 1500 m) in South Dakota. All the parts of the equipment has to be extremely clean before it’s put near by(or in) the detector. Just imagine how much effort it takes to learn anything about dark matter!
