中微子探测器

微中子探測器是觀測微中子的實驗設備。 由於微中子只參與弱交互作用,一般探測器需要建造得夠大,以接收到足夠數量的微中子訊號。 微中子探測器一般會選擇建造在地底深處,以屏蔽宇宙射線以及其它背景輻射。[1]微中子天文學目前仍未成熟,現今已確認來自地球以外的訊號來源只有太陽和超新星SN 1987A。然而未來微中子觀測站將「為天文學家提供透析宇宙的展新視野」。[2]

微中子的探測方法有許多種。

Instead of collecting light from the stars, planets or other celestial objects, IceCube looks for ghostly particles called neutrinos that hurtle across space with high-energy cosmic rays. If all goes to plan, the observatory will reveal where these mysterious rays come from, and how they get to be so energetic. But that is just the start. Neutrino observatories such as IceCube will ultimately give astronomers fresh eyes with which to study the universe.
