Most sensitive & fastest current transformer
Best non-destructive instrument to observe
pulsed or CW beams
Bandwidth Up to 1.5 GHz | Rise time < 200 ps |
Application
Used world-wide on all high-energy particle accelerators to observe very short beam pulses. Exceptional bandwidth and sensitivity are achieved by using amorphous cobalt-based alloy cores specially annealed in a magnetic field to obtain very high permeability and low loss at frequencies up to 1.5 GHz.
In-flange FCT is mounted in the beam line. Short axial length, includes a ceramic gap vacuum-brazed to kovar. Does not require bellows, wall current bypass nor electromagnetic shield. Available from CF3“3/8 to CF8“ Bakeable up to 185°C UHV compatible |
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. |
