Results are reported from an experiment on RF pulsed heating of copper at SLAC. Damage in the form of cracks may be induced on the surface after the application of many pulses of RF. The experiment consists of two circularly cylindrical cavities operated in the TE{sub 011} mode at a resonant frequency of 11.424 GHz. Each cavity received 8.5 MW, 1.2 {mu}s pulses at 60 Hz corresponding to a calculated temperature rise of 120 K on the copper surface. After 5.5 10{sup 7} pulses, the experiment was stopped and the copper surfaces were examined. Damage is present on the area of the surface where the maximum heating occurred.
