The waveguide.
-
The anode.
-
The plate cap.
-
Correct AnswerThe cathode.
For safety reasons the anode of the Magnetron is grounded and the high voltage is applied to the cathode, so Answer D. is the right answer.

Amplitude.
-
Decay time.
-
Correct AnswerRise time.
-
Duration.
The range to a target is calculated nased on the time elapsed between the rising edge of the transmitted pulse and the rising edge of the received pulse, so a fast rise time in the Magnetron's transmitted pulse is essential to accurate ranging and Answer C. is the right answer.

Correct AnswerMagnetron.
-
Klystron.
-
Beam-powered pentode.
-
Thyratron.
The Magnetron generates the RF power in a RADAR System so Answer A. is the right answer.

A type of diode that requires an internal magnetic field.
-
A triode that requires an external magnetic field.
-
Used as the local oscillator in the RADAR unit.
-
Correct AnswerA type of diode that requires an external magnetic field.
Without a magnetic field the Magneron is a vacuum tube with just an anode and a cathode, i.e. a regular diode, so Answer D. is the right answer.

The cathode must be made neutral to force electrons into the drift area.
-
A positive voltage would tend to nullify or weaken the magnetic field.
-
Correct AnswerThe anode can be operated at ground potential for safety reasons.
-
The cavities might not be shock-excited into oscillation by a positive voltage.

Because it operates more efficiently that way.
-
Correct AnswerFor safety purposes.
-
Never. It must be highly positive to attract the electrons.
-
Because greater peak-power ratings can be achieved.
