Model calculation of efficiency of gadolinium-based converters of thermal neutrons

Gadolinium for neutron detection in current nuclear instrumentation research: A review

“…Merchart et al [53] thus accessed superior performance in terms of spatial resolution, with similar figures of merit as far as efficiency and background vulnerability are concerned, also given in Table 6. Abdushukurov et al [54] investigated mathematically the design of an one-dimensional (1D) position-sensitive neutron detector based on two MSACs with a natural Gd plane in between. The Gd converter thickness is optimized with regard to the registration efficiency of the internal conversion signature between 29.3 and 200 keV, with a mean around 70 keV.…”

Modeling the registration efficiency of thermal neutrons by gadolinium foils

“…Simulations of the registration efficiency of thermal neutrons are also performed [17], [18], [19]. This fact testifies a significant interest to the gadolinium converters.…”

“…Recently many authors were engaged in the development of detectors on the basis of gadolinium converters [10], [11], [12], [13], [14], [15], [16]. Simulations of the registration efficiency of thermal neutrons are also performed [17], [18], [19]. This fact testifies a significant interest to the gadolinium converters.…”

“…In our previous calculations of the registration efficiency of Gd-based detectors [17] we used data on internal conversion coefficients from the paper [21]. There are more precise new data now [22].…”

Mathematical Modeling of the Efficiency Gadolinium Based Neutron Converters

“…The volume of a segment and accordingly probability of the electron escape becomes equal to zero in the intersection of a sphere by the plane at the distance Re i . The sum of probabilities of electron escapes for all energies, taking into account their weight contribution will determine the total electron escape probability [5,6].…”
