Beam Charge Monitor
Bunch charge integration with highest accuracy

For linacs and transfer lines, to measure injection/extraction efficiency

For laser-plasma wakefield accelerators, to measure femtosecond bunch charge

The Beam Charge Monitor (BCM) measures the beam charge of pulsed beams.

BCM processes the signal from an Integrating Current Transformer (ICT). It has a bipolar voltage output that is directly proportional to the beam charge. The ICT integrates the charge of either single micropulses or macropulses made of many micropulses. Micropulses width can be shorter than a picosecond to longer than a microsecond. Even so short pulses are faithfully integrated with high linearity and absolute accuracy.
Specially developed hybrid circuits then amplifly the charge and integrate it with low noise and high linearity. A built-in Calibration Generator provides on-line assurance of measurement reliability.
