|Abstract:||In this paper a wide dynamics neutron monitor based on BF3 neutron detector is described. The detector is used in current mode, and a front-end electronics based on a logarithmic amplifier is used in order to have a measurement capability ranging over many decades. The system has been calibrated at Polytechnic of Milan, CESNEF, with an AmBe neutron source, and has been tested in a pulsed field at the PUNITA facility at JRC, Ispra. The detector has achieved a dynamics ranging over 6 decades, proving able to measure single neutron pulses and showing saturation-free response for a reaction rate up to 10^6 s^-1. It has also proved effective in measuring the PUNITA facility pulse integral fluence.|
