Abstract: Thermal fatigue of the surface of copper subjected to multiply repeated pulsed microwave heating has been studied in order to estimate the maximum permissible acceleration rate for the CLIC collider at CERN. For this purpose, the damage of copper rings in a test cavity of the JINR-IAP facility was traced under the action of 10$^4$–10$^5$ microwave pulses at a temperature rise up to 190–250 K in every pulse. The test cavity was loaded by pulses of a high-power 30-GHz free-electron maser. Data on the dynamics of damage developed on the copper surface under the action of a strong electromagnetic field in the cavity are presented.
