Abstract A short explanation is given of the Barrel Ring Imaging CHerenkov (BRICH) detector and its performance. We discuss in brief some of the requirements to run this detector. Special attention is paid to the functioning of the Cherenkov photon detector — a photosensitive gas-filled drift chamber where the photoelectrons drift to a MWPC of special construction. We illustrate the BRICH performance with some preliminary results.

Abstract The water transmissivity is a parameter of paramount importance in the design and construction of water Cherenkov detectors which are used as neutrino telescopes. The 1/e transmission distance of 460 nm blue-green uncollimated light in deep sea-water (down to 4000 m) has been measured at three locations, in the NESTOR deployment site, off the coast of Pylos in South West Greece. The light path lengths were 7.44 m, 20.69 m and 40.37 m. The 1/e transmission distance, for depths greater than 3500 m, is found to be 55 ± 10 m.

Abstract An underwater neutrino astrophysics laboratory, to be located in the international waters off the Southwest of Greece, near the town of Pylos is now under construction. In the last two years a group of physicists from Greece and Russia have carried out two demonstration experiments in 4km deep water, counting muons and verifying the adequacy of the deep sea site. Plans are presented for a 100, 000 m 2 high energy neutrino detector composed of a hexagon of hexagonal towers, with 1176 optical detector units. A progress report is given and the physics potential of a siggle tower with 168 phototubes (currently under construction) is described.
