PICO 500 is a next generation detector that uses the principle that has been demonstrated with PICO 2L and PICO 60. The detector will have an active volume of about 500 litres and will use a synthetic quartz vessel, just like PICO 2L, PICO 60 and PICO 40L before it. The PICO collaboration is currently working on the final design of the PICO 500 experiment, focusing on the inner vessel and the pressure vessel. PICO is planning to operate PICO 500 with C3F8 to achieve a world leading sensitivity for dark matter coupling to ordinary matter though its spin.
The detector will be located at SNOLAB. Construction is expected to start in 2019. The experiment has recived full funding from CFI and the Canadian provinces. SNOLAB has approved the conceptual design of the experiment and allocated space in the underground lab for PICO 500 in the cube hall area of the lab.
The image on the side shows a schematic view of a preliminary version of the pressure vessel that will hold the quartz inner vessel with the active mass. The detector will also use the "right-side-up" concept first implemented in various test chambers and in PICO 40L.
