Description
The main task of the Target Tracker of the long baseline neutrino oscillation
OPERA experiment, is to locate in which of the target elementary
constituents, the lead/emulsion bricks, the neutrino interactions have
occurred and also give calorimetric information about each event. The
technology used consists in walls of two planes of long plastic scintillator
strips, one per transverse direction. Wavelength shifting fibres collect the
light signal emitted by the scintillator strips and guide it to both ends where
it is read by multi–anode photomultiplier tubes. The Target Tracker is
composed of 62 scintillating walls of a total surface of about 6000 m 2. Each
wall is made by assembling 4 horizontal and 4 vertical modules of 64, 7 m
long, scintillating strips. This detector has observed the first neutrino
interactions during August 2006. In this paper we will describe all elements
used for the construction and operation of this detector and we will also give
its main characteristics.
