Fast Current Transformer (FCT) is used for non-destructive measurement of pulsed beam current. It is a passive, in-flange FCT. It consists of stainless steel CF150 conflate flanges, a ferrite core and an Alumina ceramic brake. A BNC connector is provided for measurement. This FCT can be used to measure pulse beam currents of duration up to 10 µs, has a sensitivity 3 V/A and droop is less than 5%/ µs. It is UHV compatible.

1. It is a non-destructive method of beam current measurement.
2. Easy to use, UHV compatible.
3. It is an import substitute; currently FCT is not available in Indian market.

APPD, BARC has developed an In-flange, passive FCT consisting of SS304 conflate flanges, a ferrite core and Alumina ceramic brake. A BNC connector is provided for the measurement. FCT is UHV compatible and can be used to measure pulsed beam currents having pulse width up to 10µs. The Sensitivity is 3V/A and Droop is less than 5%/µs.

1. It is a non-destructive method of beam current measurement
