A comprehensive study is performed of the cathode of a multiwire proportional chamber subjected to prolonged irradiation in an experiment at the LHC. The structural-phase state of the copper foil on the cathode is analyzed via nuclear scanning microscopy, atomic scanning microscopy, Raman spectroscopy, and X-ray phase analysis. Nanostructural formations of carbon are found in the zone of spontaneous electron emission on the electrode.
