A bunch charge measurement system based on Turbo-ICT for BEPCII

A new kind of sensor Turbo-ICT has been applied to accurate bunch charge measurement in BEPCII transportation line. The system improves the resistance ability against external interference and has high signal-to-noise ratio. This paper introduces the principle, the design ideas and the function of the system. Up to now, Turbo-ICT has been used to operate online for electron bunch charge quantity measurements successfully. This paper also presents the experiment results of the sensor.
