P. Annis et al., EXPERIMENTAL RESULTS FROM A LARGE-VOLUME ACTIVE TARGET MADE OF GLASS-CAPILLARIES AND LIQUID SCINTILLATOR, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 367(1-3), 1995, pp. 377-383
We are investigating the feasibility of high-resolution tracking with
an active target made of glass capillaries filled with organic liquid
scintillator. This technique allows real time detection of short-lived
particle decays. In this paper, we report on experimental results obt
ained from an active target having 2 X 2 cm(2) cross section and 180 c
m length, installed in front of the CHORUS detector and exposed to the
CERN Wide Band Neutrino Beam. The detector consists of 5.1 x 10(5) ca
pillaries with 20 mu m inner diameter, read out by a single optoelectr
onic chain and a Megapixel CCD. Details on tests in the neutrino beam
will be reported. First neutrino interactions have been detected.
