The transmit time in the repeller space of a reflex klystron must be (n+3/4) cycles to ensure that
1
Electrons are accelerated by the gap voltage on their return
2
Returning electrons give energy to the gap oscillations
3
It is equal to the period of the cavity oscillations
4
The repeller is not damaged by striking electrons
