DUMAND at the University of Hawaii
The Deep Underwater Muon and Neutrino Detection (DUMAND) Project existed
from about 1976 through 1995. The goal was the construction of the first
deep ocean high energy neutrino detector, to be placed at 4800 m depth in
the Pacific Ocean off Keahole Point on the Big Island of Hawaii. Many
preliminary studies were carried out, from technology to ocean optics. A
prototype vertical string of instruments suspended from a special ship was
employed to demonstrate the technology, and measure the cosmic ray muon
flux in the deep ocean. Data from this Short Prototype String were, for
example, used to set the then best limits upon PeV energy neutrinos as
might be expected from Active Galactic Nuclei.
A major operation took place in December 1993, at which time one string
of photodetectors, a string of environmental instruments and a junction box
were placed on the ocean bottom and cabled to shore. While the cable laying
was successful, short circuits soon developed in the instruments and it was no
longer possible to communicate with the installed apparatus. In 1995 the
US DOE cancelled further efforts on DUMAND.
The DUMAND goal to begin high energy neutrino astronomy is being carried
forward in several ocean experiments (in order of age): NESTOR, ANTARES,
and NEMO, all located in the Meditteranean Sea, as well as the venerable
Lake Baikal Project in Asia, and the AMANDA/ICECUBE Project at the South
Pole. The DUMAND hardware was donated to the NESTOR Project in Greece, and
may yet be employed there.
