(Most of the information presented here come from
the "Openday" held at CERN on April 4, 1998.)

J.P. Fabre explains to you their intimate structure
There is no commercial manufacturer able to make
the delicate target emulsions: their development and handling need considerable
As for ordinary photographic film, they need to
be stabilized by a chemical process ("development")
after a two-years exposure to the neutrino beam.
Here is a typical vertex
as seen behind a microscope.
Automatic microscopes ans scanning
One of the most delicate job is to locate the interaction
vertices and to search for the typical signature
of tau lepton.
