Had an absolutely excellent time again today in the underground laboratory at SNOLAB. Worked with the PICO team to put another ~6000 liters of water in the shield tank. Ran a little experiment over at HALO involving Newton’s Laws and Maxwell’s Equations. Scoped out some oxygen sensors for a summer research project. Oh, and had a great time streaming a sample loaded into the ultra-sensitive gamma ray counters in the Low Background Counting laboratory for the CAPSS Summer School participants!
