The Chicagoland Observatory for Underground Particle Physics (COUPP) experiment uses stable room-temperature bubble chambers to search for Weakly Interacting Massive Particles (WIMPs), which might compose a significant fraction of the galactic Dark Matter. COUPP presently operates a 2 kg chamber at the ~300 m.w.e. depth of the NuMI tunnel at Fermilab as a test beam precursor of this project. The Coupp experiment team published first dark matter limits in Science on Feb 15, 2008. This is only the second Fermilab experimental results ever published in Science.
