Bergoz Integrating Current Transformer, ICT, Turbo-ICT, BCM

The Bergoz Integrating Current Transformer (ICT) is a capacitively shorted transformer and a fast read out transformer in a common magnetic circuit designed to measure the charge in a very short pulse with high accuracy.

The ICT integrates the signal with a time constant of 1 to 20 nanoseconds, depending on the model. Eddy current losses are negligible and the instrument is a very linear integrator for the very high frequency spectrum typical of a bunched beam signal.

ICT can be embedded inside a conflat flange for direct mounting on the beam pipe.

ICTs are designed for use with Bergoz BCM-IHR-E for signal processing.

Features

  • The ICT magnetic core and associated windings are essentially noise free
  • Measurement noise (measurement resolution) is determined by the signal processing
  • Down to 0.55 pC rms noise with BCM-IHR-E
  • Input current rise time < 1 ps

Applications

  • Short pulse charge measurement in Linacs or transfer lines
  • Slow extraction for medical therapy
  • Calibration of gas ionization chambers

 

Overview, Turbo-ICT

Features

  • CW and Macropulse Current MeasurementOptimized for low beam current ≤ 20mA
  • RF from 1MHz to 350MHz
  • Output Bandwidth >5MHz
  • Total Noise ~0.1 uArms over DC to 5MHz
  • Single Bunch Charge Measurement Optimized for low bunch charge ≤ 100pC
  • Bunch length 1fs to 1ns
  • Noise in single bunch measurement 10 fC
  • Maximum bunch repetition rate: 2MHz

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.

ICTs are designed for use with Bergoz Beam Charge Monitor (BCM) for signal processing.

Overview, BCM

Beam Charge Monitor (BCM) processes the signal from an Integrating Current Transformer (ICT). It has a bipolar voltage output that is directly proportional to the beam charge. The ICT integrates the charge of either single micropulses or macropulses made of many micropulses. Micropulses width can be shorter than a picosecond to longer than a microsecond. Even so short pulses are faithfully integrated with high linearity and absolute accuracy.

Specially developed hybrid circuits then amplifly the charge and integrate it with low noise and high linearity. A built-in Calibration Generator provides on-line assurance of measurement reliability.

Two versions are available:
  • Integrate-Hold-Reset (BCM-IHR), for pulse repetition rates from 10kHz down to single pulses
  • BCM-RF, For use with Turbo-ICT. Two modes available: Track-Continuous for CW and long macropulses (1MHz to 300MHz, 10uA to 100mA), or Sample & Hold for single bunch (Single Bunch to 2MHz, 100fC to 100pC).
