Unlike the bubble chambers of the 1960s and 1970s, COUPP bubble chambers are operated in only mildly superheated conditions, rendering them insensitive to the minimum ionizing particles that typically constitute the largest background in dark matter searches. The bubble chamber allows for rejection of other backgrounds as well - for example, alpha decays can be discriminated from signal events because they sound louder. The result is a detector with minimal backgrounds that can be easily scaled to large masses. I will introduce the field of direct detection of dark matter and discuss the status of COUPP, including results from the COUPP-4 detector operated at the deep underground site SNOLAB and a progress report on COUPP-60, currently being commissioned. |
