Station for functionality test of drift tubes of the ATLAS Muon Spectrometer

A description of the semiautomatic high voltage testing station is presented. The station was designed for the functionality test of drift tubes (DT) of the ATLAS muon spectrometer. Strong requirements for DT stability (maximum accepted leak current is 2 nA/m) and high production rate required building of a specialized testing station. It allows one to investigate leak current and cosmic count rate dependence from high voltage value in working conditions. The station performance, the test procedure and results from the first year of mass production are presented.
