Turbo-ICTs are based on the standard ICT, but with multiple cores for reduced noise and shorter output pulse duration (<3ns). Turbo-ICT

The Beam Charge Monitor measures pulsed beams charge from an ICT. It's bipolar output voltage is directly proportional to the total beam charge. Two versions are available:
BCM-IHR (Integrate, Hold, Reset), for pulse repetition rates from 10kHz down to single pulses.

BCM-RF, For use with Turbo-ICT. Two modes available: Track-Continuous for CW and long macropulses (1MHz to 300MHz, 10uA to 100mA), or Sample & Hold for single bunch (Single Bunch to 2MHz, 100fC to 100pC).
