Abstract
The design and parameters of scintillation detectors of Compton polarimeters for measuring photons formed during the annihilation of electron-positron pairs at rest are considered. The discussed setup makes it possible to measure and compare the polarization correlations of scattered annihilation photons in these two quantum states. The amplitude parameters of scatterers and scattered photon detectors obtained from preliminary tests of these detectors using radioactive gamma sources, as well as in the process of collecting experimental data, are given. The possibility of measuring and comparing the polarization correlations of scattered annihilation photons is shown.

Abstract
A diagnostic system has been developed on the gas dynamic trap (GDT) for detecting deuterium fusion products as well as X rays and γ rays produced by interactions of superheated electrons with structural elements of GDT and by capture of neutrons by nuclei of surrounding materials. The diagnostic system consists of the following three subsystems. The first subsystem is used to measure the longitudinal intensity profile of the dd-fusion reaction. It is based on diode detectors of 3.02-MeV protons and preamplifiers capable of operating with large-area diodes mounted in specially developed detector modules. The detectors are located inside the vacuum chamber of the GDT; they operate in the counting mode, which allows absolute measurements of the reaction-product flux with a time resolution of ~100 μs. Such detectors were created taking into account the operating experience of a proton detector based on an experimental diode in the GDT experiment. The second subsystem is composed of detectors developed earlier on the basis of SPM-5 plastic scintillator and a photomultiplier tube (PMT). These detectors are operated in the current mode and are intended to measure the neutron-generation intensity with a time resolution as high as 25 μs. These detectors are used jointly with the proton detectors in experiments with the additional heating to determine the contribution of γ rays and hard X rays. The third subsystem is a new neutron and γ-ray spectrometer based on a stilbene scintillator and a PMT, which was used for the first time in the experiment with deuterium plasma at the GDT facility. The detector is capable of separating particles of different types, in particular, under the operating conditions of the facility when superheated electrons are generated.

Abstract
The temperature effect plays an important role in the response function and efficiency of detectors. In this study, the behavior of doped NaI (Tl) and plastic scintillators was evaluated and compared with temperature changes, in a similar condition, for the first time. The detection system uses an experimental setup consisting of a 60Co source, NaI (Tl) detector, and a plastic scintillation detector. The results show that the recorded count rates from NaI (Tl) detector have a direct relation with temperature and lead to a 0.15%/°C error in the count rate. But in the same condition, the acquired count rates from the plastic scintillator detector were reduced with temperature increasing with a 0.57%/°C error in the count rate (inverse relation). Also, in this work, Linear and second-order polynomial regression were implemented on the recorded count rates from scintillators to compensate temperature effect. Finally, the acquired results were evaluated using the relative error (%) and diagram slope which expressed the superiority of the polynomial regression. Using this correction technique, the count rate changes reached to least and are stable with temperature fluctuations. The results of this research can be suitable for the industrial application of NaI (Tl) and plastic scintillators in level gauging, thickness gauging, and other nuclear gauging systems.
摘要 温度效应对探测器的响应功能和效率起着重要作用。本研究首次在类似条件下对掺杂 NaI（Tl）和塑料闪烁体的行为进行了评估和温度变化比较。检测系统使用的实验装置由 60Co 源、NaI（Tl）检测器和塑料闪烁检测器组成。结果表明，NaI（Tl）探测器记录的计数率与温度有直接关系，导致计数率误差为 0.15%/°C。但在相同条件下，塑料闪烁体探测器获得的计数率随温度升高而降低，计数率误差为 0.57%/°C（反比关系）。在这项工作中，还对闪烁体记录的计数率进行了线性和二阶多项式回归，以补偿温度效应。最后，使用表示多项式回归优越性的相对误差（%）和图表斜率对获得的结果进行评估。使用这种校正技术，计数率的变化达到了最小值，并在温度波动时保持稳定。这项研究成果适用于将 NaI (Tl) 和塑料闪烁体用于液位测量、厚度测量和其他核测量系统的工业应用。

Abstract
A hybrid muon hodoscope for muonography of large-scale objects has been created in the Scientific and Educational Centre NEVOD (MEPhI) with the participation of the National Research Center “KI”–IHEP. The multichannel detecting system of the hodoscope consists of a scintillation strip detector and a detector on drift tubes and is designed to detect tracks of charged particles, mainly muons, flying through the detector volume. The drift tube detector is an important recording element of the muon hodoscope, providing high angular and spatial accuracy of muon track reconstruction. The article describes the design of the drift tube detector, the principles of operation of the readout electronics, and also provides the main technical characteristics.

Abstract
A successful LINAC operation at Synchrotron Radiation Facility−Siberian Circular Photon Source (SRF SKIF) is directly related to the improvement of diagnostic methods for measuring the transverse profile and longitudinal distribution of the beam charge, which, in turn, requires the use of new materials or methods for their production. The thermal outgassing has been measured from aerogel and electrophoretically deposited P43 phosphor used in the LINAC diagnostic system of SRF SKIF.

Abstract
A source of fast and epithermal neutrons was constructed on the Prometheus medical accelerator at an energy of 200 MeV, and measurements of the yield of fast and epithermal neutrons were made using the BDMN-100 detector. A heavy NaI target was used to obtain fast neutrons. Based on the five developed different protective materials from neutrons, a channel of fast and epithermal neutrons was formed. Using the BDMN-100 neutron detector, the dose profiles at the outlet of the neutron channel were measured. The neutron source has a possible application for research work on the creation of new radiopharmaceuticals. Fast neutrons can be used for remote therapy and reliability control of electronic boards and microcircuits. The neutron beam can also be used to study biological objects and cells.
