ABSTRACT
A new detector suitable for measuring high intensity pulsed gamma-ray sources and based upon scattered-electron method is proposed. The detector has a relatively flat energy response in the range of 0.4–5 MeV and works in current mode. The performances of the detector under several conditions were studied by Monte Carlo simulation using the MCNP code. A comparison between calculations and measurements performed using the 1.25 MeV line of Co-60 is also addressed. The experimental signal produced by the detector was thus studied and decomposed into its main components in order to establish the signal-to-noise ratio (SNR). The latter is compared to SNR calculated for other type of detectors.
