CoGeNT
The CoGeNT experiment has searched for dark matter. It uses a single germanium crystal as a cryogenic detector for WIMP particles. CoGeNT has operated in the Soudan Underground Laboratory since 2009.
Results
Their first announcement was an excess of events recorded after 56 days[1] They observed an annual modulation in the event rate that could indicate light dark matter.[2] This signal conflicts with other searches that have failed to find any evidence, such as XENON and LUX. The annual modulation has continued to be seen in 3 years of data.[3]
