Microstructural Analysis of Cathode Strip Chamber Samples after Lifetime Tests

Abstract

The evolution of the structure of copper foil on the cathodes of prototype CMS chambers is studied, depending on the conditions of irradiation. Samples of the cathodes of the chamber prototypes are examined comprehensively after prolonged irradiation with a 90Sr β-source. The surface morphology of the copper foil on the cathodes caused by radiation damage from electrons is discussed.
