Multimode Harmonic Power Measurement of 40 MW Pulsed S-Band Klystrons

摘要

An array of 12 calibrated RF electric field probes on the waveguide walls are used to sample the complex field profile at the second and third harmonics where the fundamental power is in the 40 MW range at 2856 MHx. The measured amplitude and phase signals from these are Fourier analyzed to determine with good accuracy the power in each of the many possible propagating modes. (ERA citation 09:050464)
