Description

PICO-40L is a bubble chamber detector with a target material of superheated C3F8, located at the SNOLAB underground research facility outside Sudbury, Ontario. With its abundance of non-zero-spin fluorine nucleons in the detector target and its effective blindness to electron recoil interactions, it is projected to set world-leading exclusion limits in the spin-dependent dark matter interaction parameter space. Unlike previous generations of the PICO experiment, PICO-40L employs a "Right Side Up" design, with the target fluid above the chamber compression and expansion system, which is expected to eliminate a class of backgrounds from previous versions of the detector. PICO-40L is currently in the commissioning stage and is expected to start its year-long blinded data-taking run in the mid-to-late summer of this year. The analysis strategy, as well as the results from the early commissioning runs, will be presented in this talk.
