"New ultra-sensitive instrument aims to detect hints of elusive dark matter particles", UChicago News, November 11, 2015
"We expect that several tens of thousands dark matter particles per second are passing through the area of a thumb-nail," said Luca Grandi, an assistant professor in physics at the University of Chicago and a member of the KICP. "The fact that we did not detect them yet tells us that their probability to interact with the atoms of our detector is very small and that we need more sensitive instruments to find the rare signature of this particle."
