The reflex klystron as a microwave detector

The mechanism of detection in a passive reflex klystron is discussed qualitatively on the basis of elementary space-charge theory with emphasis on the character of the anoderepeller potential distribution necessary for detection. Tabulation of tangential sensitivities obtained using several different tube types is included, together with other experimental data. It is shown that there is a possibility of using reflex klystrons as tunable detectors at frequencies where crystal diode performance is relatively poor.
