摘要：

The COUPP collaboration is developing the technology of continuously sensitive bubble chambers in the pursuit of direct detection of galactic dark matter. We have built and operated a 2 kg device in an underground area at Fermilab. From that run we obtained competitive spin-dependent interaction dark matter limits. Currently we are building a 60 kg detector, which will eventually be situated deep underground. This paper describes the design of that detector and discusses the challenges associated with it.
