    "abstract": "Borexino is an organic liquid scintillator underground detector for low\nenergy solar neutrinos. The experiment has to satisfy extremely stringent low\nbackground requirements. The thin nylon spherical scintillator containment\nvessel has to meet cleanliness and low radioactivity levels second only, within\nthe detector, to the scintillator itself. Overall, the background from the\nvessel in the fiducial volume of the detector must be kept at the level of one\nevent per day or better. The requirements, design choices, results from\nlaboratory tests, and fabrication techniques that have been adopted to meet\nthis goal are presented. Details of the precautions taken during the\ninstallation of the vessels inside the Borexino detector are also discussed.",
