This picture shows the experimental facility CTF (Counting Test Facility) – the prototype of the multipurpose neutrino detector Borexino in the Gran Sasso laboratory (LNGS, Italy). Four tons of liquid scintillator is doped inside the thin nylon sphere 1 m in radius. The target is viewed by 100 photomultipliers equipped with the light cones to increase the light collection. The picture was taken from the inside of the cylindrical stainless steel tank 10 m in height, where all the construction is located. The tank itself is doped with 1000 tons of ultrapure water to protect the target from the background radioactivity coming from outside. CTF detector was taking data within 1995-2007 in the Gran Sasso laboratory.
