Measurement of the phase spectrum of electrons at the output of a traveling-wave buncher accelerator

The procedure and results of measuring the phase spectrum of accelerated electron bunches are described. At the exit from the accelerator the beam is deflected by the microwave field of a deflector at a frequency different from the bunch repetition frequency, owing to which the entry phase of bunches into the deflector is a linear function of time, and a signal whose shape represents the phase spectrum is formed in the circuit of the current receiver
