“…It is crucial that the selected neutron beam monitor fulfills the instrument requirement [8][9][10][11]. For instance, a beam monitor tested at NOP beamline in J-PARC showed a variation in the neutron detection efficiency which exceeds the tolerable level for high precision measurement at the neutron lifetime measurement [12].…”

Neutron beam monitors with high efficiency, low gamma sensitivity, high time and space resolution are required in neutron beam experiments to continuously diagnose the delivered beam. In this work, commercially available neutron beam monitors have been characterized using the R2D2 beamline at IFE (Norway) and using a Be-based neutron source. For the gamma sensitivity measurements different gamma sources have been used. The evaluation of the monitors includes, the study of their efficiency, attenuation, scattering and sensitivity to gamma. In this work we report the results of this characterization.

“…Such detectors are widely used in many neutron centres all over the world. As an example, the two-dimensional position sensitive neutron monitor developed and tested at the Frank Laboratory of Neutron Physics, JINR, Dubna can be mentioned [17]. The important feature of this monitor is the possibility to measure spatial distribution of neutron beams having intensity up to 10 8 n/(cm 2 s) with a resolution of 4 × 4 mm 2 (see figure 5).…”

Different types of neutron scattering experiment for the study of condensed matter properties pose specific and often contradictory requirements for detector characteristics. There is no single type of detector which satisfies all the criteria. Therefore, compromise is inevitable and some of the characteristics are trade off in favour of others.Present report gives an overview of detector systems presently operating at the leading neutron scattering facilities as well as some development work around the globe.
