dfct1
The Fast Current Transformer (FCT) is a wideband AC transformer with a rise time down to 175ps and a bandwidth up to 2GHz. Applications include measurements of:

  ■  Pulsed beams in particle accelerators
  ■  Partial discharge pulses from corona wires, in insulation defects
  ■  Pulsed beams in particle accelerators
  ■  Current rise in semiconductor gates, triggers
  ■  Surge current waveforms in EMI/EMC analysis
  ■  Capacitive discharge pulses

dfct2

Available in six different apertures ranging from 16mm up to 178mm. Larger apertures are available on request.


New technology
Used world-wide on all high-energy particle accelerator 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 to 2 GHz.

FCT can be embedded inside a conflat flange fo direct mounting on the beam pipe.
