AbstractAbstract
[en] A simple model is explored mainly analytically to calculate and understand the PHS of single and multi-layer thermal neutron detectors and to help optimize the design in different circumstances. Several theorems are deduced that can help guide the design.

AbstractAbstract
[en] The design and safety of the heat removal system of the Massachusetts Institute of Technology (MIT) design for a fission converter-based epithermal beam is discussed in this paper. Plate-type reactor fuel elements, used in the MIT research reactor (MITR-II), are also used for the fission converter. This fission converter-based beam provides epithermal neutron fluxes at the patient position in excess of 1010 n/cm2s with very low contamination of fast neutrons and gamma rays

AbstractAbstract
[en] The neutron detector is formed by a diamond plate with a blocking contact layer from platinum and an injecting contact layer from e.g. Ag lying opposite to one another. Preceding the blocking contact there is arranged a neutron converter from 10B or 6Li, from 233U, 235U, 239Pu, or from 238U, 237Np, 232Pa, and 23Th. The detector is mounted in an Al casing. It is operated by d.c.. By putting together two detectors with a common neutron converter it becomes possible to detect isotropic neutron fluxes. (DG) 891 HP/DG 892 MKO

Vor dem Sperrkontakt liegt ein Neutronenwandler aus B10 oder Li6, aus U233, U235, Pu239 oder aus U238, Np237, Pa232 und Th232. Der Detektor befindet sich in einem Gehaeuse aus Al. Betrieben wird der Detektor mit Gleichstrom. Durch Zusammenbau von zwei Detektoren mit gemeinsamem Neutronenwandler ist der Nachweis isotoper Neutronenfluesse ermoeglicht. (DG)Original Title

AbstractAbstract
[en] The densities of ultracold neutrons (UCN) obtained with moving solid-state converters made of polyethylene and beryllium are computed for various values of the converter thickness, temperature, and velocity of motion. A specific experimental apparatus with a moving polyethylene converter for the pulse BIGR reactor being constructed in the All-Russian Institute of Experimental Physics (Sarov) is considered. It is shown that, with a polyethylene converter moving at a velocity of 70-80 m/s, a UNC density of up to 105 neutrons per cm3 may be attained in a volume of several liters

AbstractAbstract
[en] This work describes a methodology developed for the confection of gadolinium sheet converter for neutron radiography using the gadolinium chloride (GdCl3) as material converter. Though manufactured at a relatively low cost, they are as good as the sheet converter on the market. Here, we present neutron radiography of the penetrameter, the edge spread function, the modulation transfer function and characteristic curves for each set sheet-AA400 Kodak film

AbstractAbstract
[en] Modeling of the complex neutron converters consisting of two foils made from natural Gd and its 157 isotope deposited on supporting kapton layer has been performed. Calculations for 4 fixed neutron energies corresponding to neutron wavelengths of 1, 1.8, 3, 4 A are conducted. The thickness of gadolinium converters was varied from 1 µm to 3 µm and thickness of supporting layer made from kapton is 50 µm. It is shown that at the development of the converters of such geometry it is better to use 157 isotope of Gd with optimal thickness of 1-2 µm. For converters made from natural Gd the thickness of foils should be more than 3 µm. (author)

AbstractAbstract
[en] Neutron-induced electron radiography is a technique suitable for inspection of thin samples. The first tests were performed with conventional X-ray films, which made it possible to distinguish between thicknesses of materials of the order of 1 μm. The objective of this work was to investigate the performance of the technique when an imaging plate is used instead of an X-ray film to register the image. Due to their wide dynamic range and much higher sensitivity, imaging plates offer significant advantages over the conventional X-ray films
