With Explore the Planets, investigate the planets, their moons, and understand the processes that shape them. By G. Jeffrey Taylor, Ph.D. See our DVD collection.

Neutrino detectors

Neutrino interactions with matter are extremely rare, so detecting a neutrino is very hard.

Neutrino detectors are typically large, underground tanks filled with a fluid that reacts to neutrinos. In neutrino detection, bigger is better! The bigger the tank (detector), the more neutrinos it will detect.

One example of a neutrino detector is the Super-Kamionkande in Japan.

Here's a piece of trivia for you: early neutrino detectors were filled with a type of cleaning fluid!
