| Sumario: | Large scale production of straw drift chambers requires efficient and fast methods of testing the quality of produced modules. This paper describes the instrument which is capable to measure characteristics of dark currents of straw chambers modules in automated manner. It is intended for testing the LHCb Outer Tracker detector straw chambers modules during their production. It measures the dark current characteristics at any voltage in the range from 0 V to 3 kV and stores them. These data will be then used at CERN for detector calibration. (1 refs). |
