Application
Used world-wide on all high-energy particle accelerators to observe very short beam pulses.
Exceptional bandwidth and sensitivity are achieved by using magnetic alloy cores specially treated to obtain very high permeability and low loss at frequencies up to 1.5 GHz.
Main features
- Sensitivity from 0.25 to 5 V/A
- Bandwidth up to 1.5 GHz
- Rise time ≤ 230 ps

In-air FCT
In-air FCT installation, over the vacuum chamber Requires installation of a “gap” to prevent the wall current from flowing through the FCT aperture.
The gap can be a brazed ceramic ring or an organic material O-ring depending on the vacuum requirements.
Typical installations include bellows, a wall current bypass and an electromagnetic shield enclosing the FCT completely.
