A giant tank of perchloroethylene was used as one of these devices in the (*) Homestake experiment, which detected approximately one-third of the expected number of particles being emitted by the sun.
One of these devices contains about twelve thousand glass spheres resting on 600 glass strings at the bottom of the Mediterranean. One example of these devices contains a series of digital optical modules, and was used to find "double pulse", "sugar daddy" and "lollipop" signatures by the DONUT collaboration. A giant tank of perchloroethylene was used as one of these devices in the (*) Homestake experiment, which detected approximately one-third of the expected number of particles being emitted by the sun. For 10 points, name these devices that include IceCube and Super-Kamiokande, which detect a type of light uncharged particle that rarely interact with normal matter.
