Beam transfer function measurements of accelerating beam in the Fermilab Booster

Beam transfer function measurements were performed on the accelerating beam in the Fermilab Booster with a network analyzer and a custom signal processing system. Since the booster RF frequency slews from 30 to 53 MHz in 33 ms, an intermediate frequency processing circuit was built external to the reference and receive ports of the network analyzer. This circuit permitted resolution of 2.5-kHz synchrotron sidebands while the booster RF frequency changed from 500 kHz in 15 ms.<
