I think I saw a small news in the german tv almost a year ago.
This is a set of Cherenkov detectors which should acquire the Cherenkov
radiation created in ice and coming from high energy muons which in
turn were created during interactions of muon-neutrinos (coming from
the sun, for example) with ice. Each detector is placed in a ball of about
50cm diameter, they are separated by about 2m from each other. So, on
principle, there is a 2km long "rope" which in the end (last 500m) has
some 50cm diameter "balls" separated vertically by about 2m. Then the ice
is "drilled" (with hot water, if I remember well) and the "rope" is put
down into this hole. There are a couple of such "ropes" placed in ice,
separated by some meters vertically (I don't remember how much). In the
end you get a set of Cherenkov detectors in a "grid" of tens (or hundreds)
of square meters of horizontal surface and some 1.5km - 2km beneath the
surface of the ice. The idea is to measure the exact "time" the Cherenkov
radiation coming from a single muon approaches each detector. This way one
can say from which direction the muon has come.
(Sorry, but this is all I remember from this "tv-news".)

Do you have a www page that describes this project ?
Thanks in advance,
