Recently, we have created precision narrow-band temperature sensors that allow us to measure temperature with a relative error of at least 0.005 °C. These temperature sensors are designed to study the fine structure of temperature fields in the rock solid, as well as to take into account internal temperature variations in various geophysical devices. The article considers the principal ways to achieve the required accuracy of measurements, calibration, and installation of the necessary operating temperature range of the sensors. Carrying out measurements using the developed sensors in the tunnel of the North Caucasus Geophysical Observatory of the IPE RAS in the Baksan Gorge will provide unique data on the structure and dynamics of the thermal field near the Elbrus volcano.

An experimental setup of a far-field optical microscope intended for simultaneous visualization of single nanoparticles by two different methods is described. The first method is based on a modified version of a surface plasmon resonance microscope, the second on a highly sensitive recording of fluorescent labels inserted into the observed nanoparticles. The created microscope allows visualizing nanoparticles that weakly absorb light in a selected wavelength range and are characterized by a refractive index close to its size in the surrounding liquid (polymeric nanoparticles, viruses, liposomes, intracellular microvesicles in aqueous medium). The combination of the two methods allows to increase the reliability of nanoparticles detection. The optical scheme of the dual microscope and its principle of operation are described, and examples of the registration of nanoparticles are given.

The dashed lines on the right exemplarily show cases in which the results of detection of the same nanoparticles by two methods coincide.

This paper describes an online realtime data acquisition system. The design utilizes ARM single board computers that bring very low power requirements, portability and lightweightness. We have implemented a unified approach to acquire, transfer and store the measurements. The approach takes advantages of SeedLink protocol to establish online real time data flows between the components of the system. Communication over IPv4 rely on secure virtual private networks. The system features remote management of data logger and all connected devices. For purposes of testing and technology showcase weve implemented support for a range of variometer-type magnetometers.
A prototype of a source of electrons with a magnetic beam rotation for electron-beam technologies is presented. The use of the principle of its operation will make it possible to expand the possibilities of using an electron beam in the processes of thermal processing of materials for the synthesis of heat-resistant composites and compounds, the production of nanopowders and reactive deposition of protective coatings, where there is increased gas evolution and contamination in the technological chamber, and also to produce electron-beam welding in hard-to-reach places.
The criteria and method for the exhibition of a magnetic mirror are given.
The measurements of the beam profile show:

  • the displacement relative to the plane of antisymmetry of the magnetic mirror leads to an insignificant increase in the cross section of the beam at the crossover point of the beam;
  • the beam dimensions before and after the rotation coincide;
  • the prototype beam is suitable for electron beam welding.

The paper describes the foundations of the developed calibration-free magnetic method for NDT of the level of residual mechanical stresses in constructions made of low-carbon steels. The new mobile magnetic measurement system is described, which does not require the procedure of preliminary calibration on standard samples. The key elements of the measurement system are the primary converter of the original design, as well as the principle of calculating mechanical stresses over magnetic parameters. The work of measurement system is tested on samples of low-carbon steel with 0.2 % C under the action of compressive loads in the elastic deformation region.

In work the device for measurement of dielectric characteristics of a reservoir fluid is presented. This device is designed to work in a well with a depth of up to 5 km. Measurements of dielectric characteristics are made by the capacitive divider method, and both amplitude and phase changes of high frequency oscillations passing through two measuring capacitor cells filled with the investigated fluid are taken into account. Measuring cells differ in the length of the central electrode and are designed to work in different parts of the oil-water concentration range. Based on the results of the tests, the optimal range of operating frequencies of the device is determined, depending on the design of the cells used.

Design options for a tablet-type magnetic field scanner are described. Scanners differ in the number of sensors and the way data is recorded. All sensors are fixed and scanning is performed by moving the source of magnetic field. The transition from the moving sensor to the moving source allows circumventing the number of principal problems and creating an exceptionally simple, compact and reliable design.


Fig. 1. Layout view of a magnetic field scanner.
The black rectangle 1 in the center is a Hall sensor, on the right 2 is a holder with a cylindrical magnet installed in it. To simplify the figure, the millimeter divisions on the scales are not shown. In the position of the magnet shown in the figure, the coordinates of the Hall sensor are relative to the center of the magnet: x = - 4.6 mm; y = 0 mm. The size of the scan area at the selected scanner size is 10 × 10 cm. The vertical dashed line shows the location of the array of 16 Hall sensors in the scanner of the second type, the horizontal dashed lines indicate the vertical size of this scanner

A new method for express testing of multicomponent liquid, consist principally of hydrocarbons (90% and more), is described. The new method is an alternative type of technical implementation for "electronic tongue" idea. It is based on a brand new process that provides an opportunity to identify analyzed multicomponent liquid with standard sample (etalon) and to perform liquid express analysis, avoiding its detailed composition test. In addition, standard sample (etalon) equivalence makes it possible to match full identity/concordance of analyzed liquid in technology of liquid creation, not only in elemental composition.

Analysis of exhaled air is one of the important areas of non-invasive medicine. As an example of the use of this method in scientific instrumentation, mathematical processing of mass spectra obtained on a quadrupole mass spectrometer MC7-200 is considered. The methods of data processing described on the basis of linear and quadratic discriminant analysis allow us to divide processed mass spectra of exhaled gases into two groups: mass spectra of exhaled gases of healthy people and mass spectra of exhaled gases of people with possible pathologies.

The conical achromatic prism (CAP) has a record angular dispersion equal to about 50 radians per 100% of mass variation. In CAP, electric and magnetic fields are realized whose potentials in a spherical coordinate system depend only on angular variables. The particles of a homogeneous planar parallel ion beam move in the middle plane of the CAP along similar trajectories and maintain parallelism at the exit from the CAP. The CAP also focuses on energy, and the parallelism of the volume beam is maintained due to its telescoping in the vertical direction. CAP can be used in a prismatic mass spectrometer, which in its scheme is similar to a prism light-optical spectrometer equipped with a collimating and focusing lens. The linear dispersion of the prism spectrometer is equal to the angular dispersion of the CAP multiplied by the focal length of the focusing lens. A prismatic device is designed in which three-electrode transaxial lenses are used as a collimating and focusing lens. Due to the large mass dispersion by using a positional detector located in the focal plane of the focusing lens, a mass spectrograph can also be implemented in such a device.

The paper analyzes some logical errors which exist in new theory of the quadrupole excitations for rf quadrupole mass filters which was suggested by M. Yu. Sudakov and E. V. Mamontov using the analysis of the envelopes for the stroboscopic samples of coordinates and velocities of ions in the rf quadrupole field. The paper also shows that by direct using of the equations produced by the perturbation theory it is possible to produce a clear model describing the main properties of quadrupole excitation, for which stroboscopic samplings are not required.

Keywords: quadrupole rf fields, pseudo potential of electric rf field, quadrupole excitation of ion oscillations, monodromy matrix, instability bands

A closed system of electrohydrodynamic (EHD) equations for such a specific subsection of electrohydrodynamics as electroosmotic phenomena is obtained. The EHD system does not contain the diffusion equation for the search for the field of ion concentrations. In the paper they are calculated more simply in the Debye-Hückel approximation. This makes it possible to simplify the calculation of electroosmotic potentials and ion charge densities. Correction of other equations of the EHD-system was carried out taking into account the features of electroosmotic processes. The presence of a heat conduction equation in the system makes it possible to calculate the temperature field in a liquid, which is extremely necessary for maintaining the necessary temperature regime when a new type of radiator is realized in practice.

Keywords: electrohydrodynamics, electroosmotic process, electrohydrodynamic system of equations,

For ideal focusing traps electrostatic fields having charged particle motion separated in elliptic coordinates the ion motion stability conditions are updated. Analytical exact and approximate expressions are found for fields with zero and close to zero field parameter μ values. These expressions connect initial data and field parameters to guarantee the ion motion finiteness.
