A wide dynamics neutron monitor with BF3 and logarithmic amplifier based front-end electronics
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.
