This item was taken from the IEEE Conference ' RF cavity BPM'S as beam angle and beam correlation monitors ' It has been shown that high performance cavity BPM's are capable of accurate beam trajectory angle and beam 'tilt', (x-z or y-z correlation) measurements. Such a device will be very useful for the optimization of a variety of beamlines, such as high current linacs, bunch rotators and storage rings. The signal from a nonaxial trajectory or a tilted beam is in quadrature to that observed from a simple displacement of a very short bunch. Using in-phase/quadrature-phase (I/Q) demodulation of the cavity BPM signal, it is possible to separate position and angle/tilt. In this paper, we present results of beam angle and tilt monitor tests carried out in the KEK Accelerator Test Facility (ATF) extraction line.
