SuperCDMS dark matter detector receives 34 million dollars funding

SLAC led SuperCDMS SNOLAB experiment, multi-institutional project, continues its dark matter hunting. It deepens into particles with the help of properties that were never accessible previously to researchers.

Department of Energy of the USA has signed the papers approving 34 million funding on construction in ranks of SuperCDMS or Cryogenic Dark Matter Search SNOLAB trial. The active part of the experiment will begin in the 2020s when researchers will be trying to find particles of dark matter called WIMPs.

What is WIMPs? It is weakly interactive massive particles in dark matter. All equipment will be 50 times sensitive comparing to all previous attempts. Scientists hope that it will give them answers to the biggest mystery of physics.

SuperCDMS will work on an international collaboration of 26 institutions and 111 members. The construction will be made by National Accelerator Laboratory SLAC of Energy Department.

Joanne Hewett, director of Fundamental Physics Directorate in SLAC and the head laboratory research officer says: “Understanding dark matter is one of the hottest research topics – at SLAC and around the world. We’re excited to lead the project and work with our partners to build this next-generation dark matter experiment.”

Richard Partridge, the head of SuperCDMS part in Kavli Institute for Particle Astrophysics and Cosmology confirms: “Our experiment will be the world’s most sensitive for relatively light WIMPs – in a mass range from a fraction of the proton mass to about 10 proton masses. This unparalleled sensitivity will create exciting opportunities to explore new territory in dark matter research.”

Energy Department gives 19 million dollars to the research, National Science Foundation gives 12 million dollars more, and Canada Foundation of Innovation add 3 million dollars as well.

With these money scientists using germanium crystals and silicon will trigger almost unnoticeable vibrations. To do it, they will cool down crystals to less than – 459.6 degrees Fahrenheit. Vibrations will strengthen signal from the collision of dark matter. It will show fingerprints of dark matter, from which consists 85 percent of all mater in the universe. There is only 15 percent visible matter. Dark matter is also the main driver of all evolutionary processes in the universe, responsible for Milky Way and other galaxies formation.

SuperCDMS looks like a hockey puck. It will go 2 000 meters deeper under Canada’s land. And researchers hope this tiny box will open the truth.
