Day 2 of Conference at the SAFE Credit Union Convention Center with Brian Richter and Filippos Toufexis. Stop by our booth to discuss the Very Fast Current Transformer (VFCT) from INSTRUMENTATION.

VFCT is based on an original idea from the 1970s for inductive position measurements. Via inductive coupling, the beam induces a current flowing on the surface of the vacuum chamber, the so-called wall current.

By cutting the vacuum chamber in segments equally distributed around the beam, the wall current becomes measurable by small current transformers placed around each of the segments. The sum of these individual signals is proportional to the beam current.

The internal structure of the VFCT differs considerably from normal current transformers. Resonances can be avoided. And a higher bandwidth can be reached. Yet, integration and especially length of the VFCT are like a standard current.
