[en] The purpose of the work is to study a modern method of plasma diagnostics: the method of multielectrode electrical probe system. This method eliminates the disturbing effects encountered with the single electrode probe. (author)

[en] The measuring-computer complex with replaceable Hall sensors has been developed. During magnetometric measuring on the screen of the computer display three-dimensional components of a vector of a magnetic field induction are represented depending on time in situ, and then further mathematical processing of the received information is carried out.

[en] Both Langmuir and capacitive probes were recently shown to provide more information on the periodical phenomena in a positive plasma column. In this paper we present a method for measuring the coupling capacitance between plasma and Langmuir and/or capacitive probes. The experimental data agree fairly well with theoretical predictions. Thus, both probes could be used for quantitative estimation of the plasma potential variation for ionization waves and echo phenomena. (Author)

[en] In order to determine the calibration curve of a neutron gauge a specific experimental setup has been installed in our soil physics laboratory. The technique theory is that the calibration curve of a particular soil is a function of its chemical composition and bulk density only. Counting measurements were performed with the soil in air-dried and saturated conditions. Counting times were chosen in order for achieving the overall data precision.

[en] The technique of measuring and dosing neutrons using the PRESCILA probe structure studied and proposed by Los Alamos National Laboratory (USA) has shown that the ability of the neutron dosimeter to meet the measuring range energy is wide from thermal energy to 100 MeV and less dependent on energy. The structure of detector is a dual-scintillator ZnS(Ag) + ⁶LiF and ZnS(Ag) + plastic, using both fast and thermal types, with a structure of detector Prescila like that It also measuring high energy but has small volume and volume, directional response, gamma rejection up to 2 mSv/h. Based on the outstanding features of the Prescila detector, the research team has studied the structure of Prescila detector, designed and manufactured A block of analog electronic to receive and process transducer signals and electronic blocks, Digital function and function response of the device. We also used the theory in measurement radiation detection for neutron, the calibration dose method using the ²⁴¹Am -⁹Be bare source build the calibration curve at laboratory and calibrated at the secondary standard dosimetry laboratory. Initially, the research team has built a complete neutron survey meter with built-in basic applications: measuring neutron dose rate and cumulative dose with high sensitivity, accuracy and response wide range (from thermal neutron to fast neutron) structured in compact portable form. This paper presents a summary of the initial results in the research and manufacture of experimental neutron survey meter using Prescila structure probe in the framework of implementing the project: “Research and manufacture equipment testing Measuring neutron dose to control neutron radiation dose used in industry”.
