High power klystron tuning mechanism having means for detecting non- synchronous tuning channel conditions

摘要

A high power klystron turning mechanism identifies which tuning channel has been set. A plurality of tuners are inserted into individually associated cavity resonators. A tuner supporting mechanism includes a plurality of screws which protrude to force the tuners predetermined distances into the cavity resonators. A detector detects the position of the tuner support mechanism, and therefore how far the protruding screw structure has forced a tuner into the cavity resonators, which, in turn, indicates the tuning. The detector comprises a preset plate which selectively operates a plurality of switches at locations corresponding to the protruded screws and at another location in order to generate a more accurate tuning identification. The detector may be either a light-photo cell combination or mechanical switches.
