Description

The PICO direct Cold Dark Matter search experiment is installed at SNOLAB, Sudbury, Ontario, Canada. The detection principle is based on the superheated liquid technique. PICO-2L is the first PICO collaboration bubble chamber detector to use C3F8 as the superheated liquid. The detector is mostly sensitive to spin-dependent and low mass spin-independent WIMP interactions. The active mass of the detector is 2.9 kg and it is presently taking data underground. Some of the data analysis methods and tools being applied to understand the detector’s performance will be discussed.
