Overview The Turbo Integrating Current Transformer (Turbo-ICT) is based upon the standard ICT, but is made with more than one core: 2,4,or 8 cores adjacent or superimposed in a single In-flange package.
A combination of series and parallel windings allows control of the Turbo-ICT output impedance in order to match the first amplifier impedance to lower the amplifier noise.
A lower-loss alloy to transfer charge through Turbo-ICT up to 350 MHz, while core loss remains under 1%. Output pulse duration is 3 ns compared to 70ns for traditional ICT. The increased output amplitude improves the signal-to-noise ratio by 5.
