Description
Chemical reactions in the avalanche plasma lead to formation of deposit on the electrode surfaces thus causing degradation of operating characteristics of gaseous detectors and limiting their long-term use in particle physics experiments. Various surface non-destructive complementary techniques were employed for detailed characterization of deposit accumulated on the surface of electrodes subjected to a long-term exposure of β-source 90Sr in the gas mixture of 40% Ar, 50% CO2 and 10%CF4, in the course of CSC longevity tests. Chemical composition, morphology, crystal and amorphous structure of phases constituting deposit were studied.
