CACTUS (Converted Atmospheric Cherenkov Telescope Using Solar-2) was a ground-based, Air Cherenkov Telescope (ACT) located outside Daggett, California, near Barstow. It was originally a solar power plant called Solar Two, but was converted to an observatory starting in 2001. The first astronomical observations started in the fall of 2004. However, the facility had its last observing runs in November 2005 as funds for observational operations from the National Science Foundation were no longer available. The facility was operated by the University of California, Davis but owned by Southern California Edison.It was demolished in 2009.

Расположен в Даггетте, штат Калифорния, США, неподалёку от Барстоу. До 2001 года на этом месте была солнечная электростанция, называвшаяся , которая была переоборудована для научных исследований. Первые астрономические наблюдения были проведены осенью 2004 года. Однако средств на научные цели хватило только до ноября 2005 года. Космические гамма-фотоны, попадая в атмосферу Земли, порождают в ней вторичные электроны, которые в свою очередь, излучают фотоны вследствие эффекта Вавилова-Черенкова. Это излучение и должен фиксировать C.A.C.T.U.S. Таким образом, C.A.C.T.U.S., с одной стороны является телескопом, поскольку фиксирует электромагнитное излучение, с другой стороны, методы детектирования сближают его с установками для изучения широких атмосферных ливней, которые порождаются космическими лучами.
