Summary of aging studies in wire chambers by AFS, DELPHI and EMC groups
Description
Aging rats have been measured in Ar/C2H6, Ar/C2H6/methylal, Ar/CO2 and Ar/CH4/H2. Deposits were observed on the anode wires only: they were insulating and contained silicon and oxygen in most cases. Impurities from the gas supply, presence of G10 and oil bubbler and geometry of cathodes are shown to affect aging. Addition of water vapor reduced aging while addition of hydrogen had no effect. The paper summarizes studies on radiation damage of wire chambers carried out at CERN by groups involved in the jet chamber for Axial Field Spectrometer (AFS), the TPC and RICH for DELPHI the EMC Muon Spectrometer and a common DELPHI/EMC effort
