  • Tuning mechanism for high power klystron having photointerrupter control means
    Patent number: 5281895
    Abstract: The channel tuner mechanism for a high power klystron. A plunger support mechanism is connected to each plunger which constitutes a part of a vacuum tube of the klystron for normally applying to the plunger a force in a reverse direction away from the vacuum tube of the klystron. A preset plate has a plurality of protrusions arranged in contact with the plunger support mechanism to impart thereto a mechanical displacement. A drive mechanism is provided for coupling or decoupling the protrusions of the preset plate to and from the plunger support mechanism to which the plungers are connected. A detection unit is provided to detect which protrusion is selectively connected to the plungers.
