1.	Which of the following routes are the microwaves entering from the klystron towards the cavity?(a) Oscillator(b) Attenuator(c) Circulator(d) ReflectorThe question was posed to me in unit test.I need to ask this question from Basic ESR Spectrometer in section Electron Spin Resonance Spectrometers of Analytical Instrumentation
Answer» The correct OPTION is (c) CIRCULATOR The BEST explanation: Circulator routes the microwaves entering from the klystron TOWARDS the cavity. The sample is mounted in the cavity.
