NMR stabilization of the magnetic field by a III1-1 magnetic inductometer in the frequency modulation modeSpringer Science and Business Media LLC - Tập 52 - Trang 613-614 - 2009
A. V. Anisimov
As applied to the problem of stabilizing the magnetic field of the NMR relaxometer-diffusiometer by a III1-1 magnetic inductometer, we propose a simple method for changing the III1-1 magnetic inductometer to the frequency modulation mode to exclude the field modulation arising from modulating coils of the III1-1 sensor at the studied sample location.
A system for measuring the electromagnetic characteristics of the KTM tokamakSpringer Science and Business Media LLC - Tập 51 - Trang 799-804 - 2008

A system for measuring electromagnetic characteristics of the KTM tokamak physical setup with the magnetic thermal insulation of plasmas includes primary signal-processing modules, interface converters, and data recording unit. When the input signal varies from −300 to +300 V in a 0-to 500-kHz frequency band, the reduced error of channels measuring signals from sensors is 1.5%. The system uses a c...... hiện toàn bộ

The design features of the electron accelerator with a large-area 200-keV beam and results of its investigation are described. The accelerator is based on a set of discrete longitudinal filament cathodes and operates in the continuous mode. The cross section of the beam extracted into the atmosphere is 40 × 50 cm2, and the maximal current density of the extracted electron beam is up to 100 μA/cm2....... hiện toàn bộ
A Study of the Collective Beam Instabilities in the Damping Ring of the VEPP-5 Injection ComplexSpringer Science and Business Media LLC - Tập 65 - Trang 878-886 - 2022
V. V. Balakin, D. E. Berkaev, F. A. Emanov
The collective beam instabilities in the damping ring of the VEPP-5 injection complex have been investigated. Wakefields created by the charged-particle beam distort the potential well of the accelerating RF system, which leads to beam lengthening and to distortion of the shape of its longitudinal distribution. The longitudinal beam profile has been measured by a dissector and a streak camera, and...... hiện toàn bộ
A low-voltage ionization chamber for the ITERSpringer Science and Business Media LLC - Tập 52 - Trang 260-264 - 2009
Yu. V. Gott, M. M. Stepanenko
An ionization chamber with an operating supply voltage of 10 V has been designed for use at the ITER. The sensitivity of the chamber filled with air at atmospheric pressure is 100–200 times higher than the sensitivity of the chamber pumped down to a pressure of 10−3–10−4 Torr. It is shown that application of the supply voltage modulation technique allows the pickup noise to be substantially reduce...... hiện toàn bộ
Production of probes with carbon nanotubesSpringer Science and Business Media LLC - Tập 53 - Trang 903-905 - 2010
S. V. Antonenko, O. S. Malinovskaya
A method for producing carbon nanotubes by magnetron sputtering of a carbon target is proposed. It allows modification of traditional probes for probe microscopy using carbon nanotubes, thus substantially improving their characteristics. Probes with nanotubes with a tip radius of rounding of several nanometers can be used for precise scanning, quality control of samples, and nanolithography.
