The pulse compressor is located after the klystron to
increase the power peak by storing the energy at the
beginning and releasing it near the end of klystron output
pulse. In the CTF3 [1] pulse compressors a doubling of
the peak power is achieved according to our needs and the
machine parameters. The magnitude of peak power, pulse
length and flatness can be controlled by using a phase
modulator for the input signal of klystrons. A C++ code is
written to simulate the pulse compressor behaviour
according to the klystron output pulse power. By
manually changing the related parameters in the code for
the best match, the quality factor and the filling time of
pulse compressor cavities can be determined. This code
also calculates and sends the suitable phase to the phase
modulator according to the klystron output pulse power
and the desired pulse length and peak power
