Following the success of the second run of PICO 60, the PICO collaboration designed a new type of bubble chamber for dark matter searches. This chamber eleminates the need for a buffer liquid which appears to be responsible in large parts for the activation of backgrounds in conjunction with particulate contamination inside the vessel. PICO 40L is the first detector that will be constructed using this "right-side-up" principle. Currenty it is planned ot deploy this chamber at SNOLAB in 2018. All major parts have been assembled under clean room conditions and the final assembly is now underway in the underground lab.

At the moment the PICO collaboration is in the process of assembling the remaining parts of the new PICO 40L detector. Stay tuned for new results from this detector in 2019.
