Device for detecting dark matter gets funding from Energy Department


  • The US Department of Energy is investing $460,000 in research at Texas A&M University to develop a device to detect and confirm the existence of dark matter.
  • Physicists are unsure exactly what particles to look for, so they have agreed upon several possibilities. Among them is a particle known as a weakly interacting massive particle, or WIMP.
  • The A&M device uses cryogenically cooled germanium and silicon to record WIMPS as they strike the earth. A&M physicists and their colleagues plan to place the devices in deep mine shafts to protect them from the typical radiation that enters the atmosphere.
  • The Energy Department grant supplements an earlier federal grant of $1.675 million in the project.

“A dark matter particle passes through us every second, yet we do not feel it due to their extremely rare interaction with ordinary matter.”
