Charge Transformer
    Rise time Droop Input pulse length
Integrating Current Transformers give unique capability in the measurement of pulse charge with a noise level down to less than 1pC and pulse lengths to less than 1psec. Bergoz ICT
<1ps <2%/µs - <20%/µs <2 µs
ICTs embedded inside a conflat flange for direct mounting on the beam pipe In-flange ICT
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).

Position Monitor
    Resolution Frequency Response Beam Intensity
The Multiplexed Beam Position Monitor is optimized for electron/positron Storage Rings. The MX-BPM features: 
 •  X and Y output ±10V. 
Bergoz MX-BPM
The Log-Ratio Beam Position Monitor is optimized for single pass beam bunches as in linacs, boosters and transfer lines. Bergoz LR-BPM
The S-band / L-band Beam Position Monitor (S–BPM) is an electronics module for fast analog processing of beam pickups signals. Bergoz LR-BPM
Profile Monitor
