  • A Probe Method for Microwave Diagnostics of Pulsed Plasma
    • Abstract: —An original method for microwave diagnostics of pulsed plasma is proposed and tested. The object of the diagnostics is a shock-compressed plasma layer that is formed when a high-speed plasma jet created by a magnetic-plasma compressor is decelerated by a barrier. The essence of this method consists in placing a small resonant cavity on the plasma-jet path. This cavity is simultaneously a barrier and a diagnostic tool. The plasma parameters (the electron concentration and the electron-collision frequency) are calculated from the measured values of the probing microwave signal power transmitted through the resonant cavity and reflected from it.

The proposed technology makes it possible to advance the search for an optimal filter design to meet the quality requirements for radiation therapy. The results of calculations are presented in comparison with the experimental data obtained at the linear proton accelerator of the INR at beam energies of 160 and 209 MeV.

  • Generation of High-Power High-Voltage Nanosecond Rectangular Pulses by
           Summing Quasi-Harmonic Currents
    • Abstract: An approach to designing generators of high-power rectangular high-voltage pulses of nanosecond duration based on a Fourier representation of these pulses is considered. The design of a gigawatt-power-level generator that consists of partial-current formers, a switch, and a charging device is described. The partial-current formers are based on the use of segments of coaxial lines, the switch is manufactured in the form of a multigap gas-filled spark gap, and the charging device is a Tesla transformer that is built into one of the coaxial lines. The results of the generator tests that demonstrate the capabilities of the considered approach are presented.

  • A Radio Interferometric Correlator Based on Graphics-Processing Units
    • Abstract: — A correlator capable of processing data streams at a maximum rate of 16 Gb/s from each station in quasi-real time mode has been developed to process observations on new RT-13 radio telescopes of the Quasar VLBI network. The total data stream at the correlator input is as large as 96 Gb/s. The correlator is software-controlled and implements the FX processing algorithm. Graphical processing units manufactured by NVIDIA are used to perform the most laborious operations: fast Fourier transform, spectrum multiplication and addition, and extraction of phase calibration signals. The correlator, which was produced in 2014, has been processing observations of the Badary and Zelenchukskaya Observatories of the Quasar VLBI network for more than 2 years and a number of UT1-UTC World Time estimates have been obtained.

  • A Function Generator for Calibration of Electromagnetic-Field Recorders
    • Abstract: A low-frequency function generator for calibrating measuring channels of electromagnetic-field recorders in the frequency range from one hertz to tens of kilohertz is described. One feature of the device is the stability and high-precision phase synchronization of the output signal with a coordinated universal time provided by a GPS/GLONASS receiver. The application of the developed device made it possible to increase the accuracy of calibration of the measuring channels of receivers in a very low frequency range and, as a consequence, the accuracy of measuring the phase velocities of artificial and natural electromagnetic signals of ultralow- and very-low-frequency bands.

  • An Automated System for Measuring the Current Density of a
           Pulse–Periodic Electron Beam with a Large Cross Section
    • Abstract: —In an electron source with a mesh plasma cathode on the basis of a low-pressure arc discharge, studies of the spatiotemporal stability of a pulse–periodic beam with a large cross section (750 × 150 mm2), which was extracted into the atmosphere through an output foil window, were performed. The automated system that was used in the studies allowed real-time measurements with the ability to visualize the data on a computer. This system provides an accuracy of measurements of no worse than ±2%; it differs from the known analogues in the compactness, reliability, and simplicity of its design and allows studies of the current-density distribution over the beam cross section in a wide range of beam parameters, such as the beam energy, beam current, and beam-current pulse duration. A satisfactory coincidence of the previously obtained data and the present experimental data is shown with the possibility of substantially increasing the accuracy of setting up a scientific experiment and, consequently, the speed of debugging and the reproducibility of the technological process.

  • Reconstruction of TOF Spectrometer Experimental Data Using the
           Step-by-Step Shift Method
    • Abstract: — A method for mathematical treatment is considered for experimental data from pulsed time-of-flight spectrometers, whose response to measurement-initiating pulses is represented by their convolution with the pulse response of the system. The proposed method of step-by-step shifting and its modifications are intended to correct the system response when the initiating pulse is distorted and also to reconstruct the response from a shorter pulse. Within certain physical constraints, this method is an alternative for technical methods associated with difficult scientific and technical problems that require considerable material costs. The inaccuracies of the reconstruction are estimated. An example of the reconstruction of experimental data from the neutron time-of-flight spectrometer at the INR is considered. The method is applicable to reconstruction of output data from any systems that are linear with respect to the input signals and are invariant to time shifts.

  • A Scanning SXR Spectrometer Used in Experiments on ECR Plasma Heating at
           the L-2M Stellarator
    • Abstract: —A diagnostic complex that is based on a scanning soft X-ray spectrometer has been developed at the Prokhorov General Physics Institute. The diagnostic complex is intended to measure the radial profiles of the plasma electron temperature in the L-2M stellarator. The maximum counting rate of the spectrometer is 2.0 × 105 pulses/s. It allows measuring of SXR spectra in the energy range of γ-photons of 1–80 keV. The spectral resolution of the spectrometer measured using a source of radioactive radiation with energy of E = 5.89 keV (55Fe) was ΔE = 320 eV (FWHM). The scanning system makes it possible to measure SXR spectra along the chords lying in the angular range from –13.5° to +26.5°. Negative and positive angles correspond to chords below and above the equatorial plane of the facility, respectively. The radial resolution of the spectrometer at the plasma axis is ~1.7 cm. The first results of spectral measurements in experiments at electron cyclotron resonance plasma heating at the L-2M stellarator are presented.

  • Determination of the 14 C Concentration in a Liquid Scintillator for a
           Neutrino Detector
    • Abstract: A setup has been developed for studying ultralow 14C concentrations in liquid scintillator samples for a large neutrino detector. The setup is located at the low-background underground laboratory of the Baksan Neutrino Observatory (Institute for Nuclear Research, Russian Academy of Sciences) at a depth of 4900 m of water equivalent. The 14C concentrations in a liquid scintillator based on linear alkyl benzene, the background counting rates, and the spectra of particle energies deposited in the technological scintillator sample have been measured. The ratio 14C/12C = (1.41 ± 0.12) × 10–16 has been obtained. A model of the γ-ray background has been developed, with which it is possible to extract the energy spectrum of 14C and reduce the systematic uncertainty of measurements.
