    Compound detector with selective sensitivity to intermediate neutrons (1995)

    Notes: Abstract A compound detector based on the23Na(n,γ) reaction in a boron shield is investigated. The detector cross section was calculated assuming that the spectrum inside the shield is a sum of two components, one due to direct penetration of neutrons through the shield wall and neutrons scattered in the shield mass. Also investigated was the effect of hydrolyzing varnish in the shield and the size of the activation detector on the detector readings.

    High-sensitivity activation neutron detector (1995)

    Notes: Abstract We demonstrate that neutron fluences of nearly 1000 cm−2 can be measured when the fonctions of an activation detector and a device for recording induced activity are combined in one object i.e., a NaI(Tl) scintillation crystal. The beta radiation of the product from the127I(n, γ)128 reaction is detected with close to 100% efficiency by the crystal. The detector can be used in work with low-intensity sources of neutron fields such as neutron generators, radiosotope sources, and TOKAMAK devices.

    Inclusion of the properties of the moderator when reconstructing the spectrum from activation detector readings (1995)

    Notes: Abstract The neutron balance equation in the age approximation is proposed as an additional condition imposing restrictions on form of the neutron spectrum for a unique solution of the improper problem of reconstructing a neutron spectrum. The solution is not limited to the range of application of the age approximation and can be extended to a medium containing water. The geometric parameter and a number of other quantities that appear in the expression for the neutron spectrum are determined from the condition for best agreement between the measured and calculated activation integrals.
