S. Buontempo et al., CONSTRUCTION AND TEST OF MODULES OF THE CHORUS CALORIMETER, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 344(1), 1994, pp. 85-91
The CHORUS Collaboration is presently building a new detector for the
search of nu(mu)-nu(tau) oscillations in the CERN neutrino beam, the e
xperiment being sensitive to a mixing angle an order of magnitude smal
ler than the present limit. The basic components of the CHORUS ''hybri
d'' detector are an active target made of nuclear emulsions, an air co
re spectrometer with scintillating fiber tracking, a high resolution c
alorimeter and a muon spectrometer. An account is given here of the de
sign of the 110-tons compensating calorimeter, made of 1 mm diameter s
cintillating fibers embedded in a lead matrix, and of the test results
from the first modules produced.
