In the framework of the NESCOFI@BTF project of the Italian Institute of Nuclear Physics, different types of active thermal neutron sensors were studied by coupling semiconductor devices with a suitable radiator. The objective was to develop a detector of small dimensions with a proper sensitivity to use at different positions in a novel moderating assembly for neutron spectrometry. This work di...

A new type of solar neutron detector (NEM) was launched by the space shuttle Endeavour on July 16th, 2009 and it began collecting data on August 25th, 2009 at the International Space Station (ISS). In this paper we introduce not only preliminary results obtained by the NEM-FIB detector but also a possible solar neutron detection in association with the M3.7 solar flare on March 7, 2011.

This communication presents the main results about the design and in-house fabrication of a new solid-state neutron detector, which produces a DC output signal proportional to the thermal neutron fluence rate. The detector has been developed within the framework of the 3-y project NESCOFI@BTF of INFN (CSN V). Due to its sensitivity, photon rejection, low cost and minimum size, this device is su...

This Paper describes the work done analyzing the neutron capture on the Double Chooz detector located at northern France; this detector is searching for the oscillation of electron antineutrinos produced by a nuclear power plant. Neutrinos and also antineutrinos, of which there are three types, have been found to oscillate from one type to another. But these oscillations are governed by several...

The Modular Neutron Array (MoNA), a highly efficient time-of-flight neutron detector, is being constructed for use at the National Superconducting Cyclotron Laboratory. The modular design of the detector provides significant flexibility and allows the bulk of the assembly and testing to be done by undergraduates at nine of the schools participating in the project. r 2003 Elsevier Science B.V.

There are several goals for the neutron source strength monitor system for the International Thermonuclear Experimental Reactor (ITER). Desired is a stable, reliable, time-dependent neutron detection system which exhibits a wide dynamic range and broad energy response to incident neutrons while being insensitive to gamma rays and having low noise characteristics in a harsh reactor environment. ...

We measured the neutron decay lifetime by counting in-beam neutron decay recoil protons trapped in a quasi-Penning trap. The absolute neutron beam fluence was measured by capture in a thin (6)LiF foil detector with known efficiency. The combination of these measurements gives the neutron lifetime: τ n = (886.8 ± 1.2 ± 3.2) s, where the first (second) uncertainty is statistical (systematic) in n...
