Suministro de fabricación de cúpulas de polimetacrilato de metilo de muy alta transparencia a luz ultravioleta por termo conformado para la obtención de cubiertas anti-implosión para fotomultiplicadores de 20 pulgadas para el experimento Hyperkamiokande.

TENDER DESCRIPTION

Hyper-Kamiokande (HK) is the project for the construction of an international neutrino telescope, a development of the Kamiokande and Super-Kamiokande detectors. The HK detector will be built 620 m underground in order to observe neutrinos, proton decay, and other physical phenomena. The experiment will be carried out in a huge cylindrical water tank, approximately 70 m in diameter and 70 m in depth, filled with one megaton of extremely transparent “ultrapure water,” on the walls of which tens of thousands of photosensors (Photo-Multiplier Tubes, ‘PMTs’ hereafter) will be installed, sensitive to light known as Cherenkov light produced by particles such as neutrinos interacting with the water. Spain participates in this major research infrastructure through the LSC Consortium, which will be responsible for coordinating and developing the Spanish participation in the construction of the HK neutrino detector, including financing new projects and actions to be carried out in HK for the design, manufacture, and installation of photomultiplier protection capsules. To this end, an “anti-implosion” cover has been developed for each of the 20-inch PMTs of the HK experiment, consisting of…
