The CWCT current transformer and its accompanying BCM-CW-E electronics allow accurate, high-resolution beam current measurements. This is achieved by combining a high-droop current transformer with low-noise sample-and-hold electronics. Thanks to a fast response time on the microseconds level the system can be applied not only to CW beams but also macropulses. Pulse repetition rates may range from 10MHz to 500MHz, rendering CWCT and BCM-CW-E suitable for a wide variety of accelerators. We
