Hs. Ahn et al., STUDY OF CHARACTERISTICS OF THE BELLE CSI CALORIMETER PROTOTYPE WITH A BINP TAGGED PHOTON-BEAM, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 410(2), 1998, pp. 179-194
Results of the test of the BELLE barrel calorimeter prototype using a
tagged photon beam are presented. The prototype consisted of 36 CsI(TI
) counters with the same preamplifiers and shapers as in the BELLE cal
orimeter. The measurements were carried out at the VEPP-4M collider wi
th the tagged photon beam provided by the ROKK-1M facility. The energy
resolution for photons was measured in the energy range 40-800MeV. Th
e achieved energy resolution was 3% for 40MeV and 1.5% for 800MeV phot
ons. The results are consistent with the Monte Carlo simulation taking
into account effects of the electronics noise. (C) 1998 Elsevier Scie
