RF pulsed heating is a process in which a metal surface is heated by a pulsed RF source of power. The experiment consists of two circularly cylindrical cavities operated in the TE011 mode at a resonant frequency of 11.424 GHz. These cavities are connected by a magic tee and driven by a 50 MW X-band klystron. Each cavity received 8.5 MW, 1.2 microsec pulses at 60 Hz corresponding to a calculated temperature rise of 120 K on the copper surface.
Damage is present on the area of the surface where the maximum heating occurred.
