Welcome!
We employ the Atom Trap Trace Analysis (ATTA) technique to measure ultralow 85Kr contamination in liquid Xe detectors, used by the XENON Collaboration to directly detect dark matter.

The ATTA experiment is funded by the NSF MRI program. We would like to thank the NSF for the continued support of the XENON experiments. The ATTA lab is located at Morningside Campus, Pupin Hall Room 1004, 550 West 120 Street, 10027 New York, NY.
