The CEI2F is a very sensitive current to frequency converter. Its main application is for use with an ionisation chamber as a pulsed gamma radiation monitor as found in particle accelerators. When used in this way, this amplifier is sufficiently sensitive to measure natural background radiation. However, with minor modification, this current amplifier would be suitable for use with a compensated ion chamber (CIC) for neutron flux measurement.
Input currents from 2 x 10
-15A to 2 x 10
-5A can be measured. Two simultaneous, overlapping, 1Hz to 100kHz pulse rate outputs are available, covering the upper and lower current ranges. A low-noise EHT supply is included to polarise the ion chamber. Two output pulse streams are simultaneously available covering the low and high regions of the input current range, ensuring a good pulse rate even at very low input currents.
