Description

The performances of a liquid argon calorimeter with large gaps (2.8 cm) between electrodes wepe studied in 6.6-36 GeV electron beam and 40 GeV hadron beam at the IHEP accelerator. The calorimeter operational mode provided a signal independent of the charge generation point in the gaps between electrodes thus, the sampling fluctuations were reduced. The value measured for the sampling fluctuations turned out to be eqUal to σ/E=0.04 x Esup(-1/2)% (E in GeV). The calorimeter space and angular resolution has been determined. The RMS level of the noise signals is 82 MeV for the whole detector
