Had an awesome 12 hour shift in the underground lab yesterday. Took time to visit the future site of the # PICO -500 experiment. It will be constructed inside this water shield tank, formerly home to the MINICLEAN # darkmatter search experiment. https://chirp.cooleysekula.net/attachment/13e43e9cee837974a0e57ca319a8d9a4a178271a134fcd9b7fe0c12c32f36feb/view
